2026 Minimum Spec: STARVIS 2 & HDR & Low Power Parking Mode
VIOFO BP100 Dash Cam Battery Pack, and EP100 Extension Pack are finally here.
All items sent by Viofo for test & review, thank you very much.

October 2022 @BlackboxMyCar sent the PowerCell 8, (EGEN of Korea) for test & review, (released in 2021); BBMC POWERCELL 8 TEST & REVIEW
I consider the PC8 my “gold standard” for comparison with all other dash cam battery packs.

December 2022 BlackVue sent the B-130X (EGEN Korea) for test & review; BLACKVUE B-130X TEST & REVIEW
I found the B-130X’s BMS to be slightly more advanced in regard to cold weather charge protection.
However, I much prefer the PC8’s HIGH / LOW switch to control “HIGH” 9 Amp Hardwire Charging, and “LOW” 6 Amp Cigarette Lighter Plug Charging.

September 2023 Thinkware sent the U3000 for test & review, (no HDR).
Night time image quality was incredibly unacceptable, I sent it right back.
Unfortunately I missed the opportunity to test & review the BAB-95 Battery Pack, (EGEN Korea).
I was looking forward to testing BAB-95 because it was the first EGEN Korean made battery pack with 3-Wire input charging, and voice notifications through connected dash cam to announce things like; “battery life percentage”.

September 2024 70mai sent the BL96NNX for test & review; 70mai BL96NNX TEST & REVIEW
The 70mai dash cam battery pack was a big deal for a few reasons;
1.) Previous “mainstream” dash cam battery packs were made by EGEN Korea.
The 70mai unit was the first “mainstream” Chinese made dash cam battery pack.
2.) At the time EGEN Korean made dash cam battery packs were around $400.
The 70mai unit was released around $150.
This made auxiliary battery parking mode accessible / affordable to customers who previously could not justify $400 price of admission.
3.) 8 Cell configuration, instead of 20 Cell, (EGEN Korea).
4.) 10 Second delay “soft-start”
5.) 3-Wire Input Charging configuration, (ACC / ignition trigger)

November 2025 enter VIOFO BP100 & EP100.
It seems like each new dash cam battery pack is standing on the shoulders of the previous “generation” with improvements.
I’ve been testing / using BP100 a few months, so far I like it.
However it does have a few "convenience features” I think are missing, that if added would turn BP100 into "heavenly perfection".

BP100 Q&A

Q: Does BP100 only work with Viofo Dash Cams, or will it work with any dash cam?
A: BP100 is “universal” and works with any dash cam.
However, just like BlackVue B-130A, and Thinkware BAB-95 the VIOFO BP100 has some neat baked-in features that only Viofo dash cams utilize.

Q: Why buy BP100 (98Wh) for $280, when I can get a Power Bank (96Wh) for $20?
A:
More Safe = LiFePO4 (lithium iron phosphate)
Less Safe = Li-ion (lithium-ion) & Li-Po (lithium polymer)


Q: Why buy BP100 (98Wh) for $280, when I can get a LiFePO4 Power Sation (245Wh) for $180, (2.5x more capacity & $100 less)?
A: Convenience, (3-wire ACC / ignition trigger for parking mode)

Q: Why separate APP for BP100 (VIOFO Battery)?
https://apps.apple.com/us/app/viofo-battery/id6740014533
Why can’t the all-new VIOFO记录仪 APP be used with BP100?
https://apps.apple.com/us/app/viofo记录仪/id6738685801
Using / maintaining two separate APPs, (one for camera, one for battery) is confusing, and not user friendly.
Why can’t we have one single APP to control both camera & battery?
A: TBA

Q: Can BP100 18 Month warranty be extended to 24 Months with product registration just like Viofo cameras?
A: TBA

Q: Why are all these Dash Cam Battery Packs under 100Wh capacity?
98Wh = Viofo BP100
96Wh = BBMC PowerCell 8
96Wh = 70mai BL96NNX
96Wh = BlackVue B-130A
96Wh = Thinkware BAB-95
I want the 153Wh capacity of the massive beast IROAD Powerpack Pro 12, or larger; IROAD POWER PACK PRO 12
A:
Due to transportation / shipping regulations by;
FAA Federal Aviation Administration
DOT Department of Transportation
USPS, UPS, FedEx, DHL, etc.
All "lithium type batteries” over 100Wh capacity are subject to stricter safety regulations.
"Lithium type batteries” under 100Wh capacity are faster, easier, cheaper to transport to the customer, as well as return shipping to the manufacturer / retailer for warranty claims.
This is the difference of being allowed on cargo / passenger aircraft, or ground transportation, (truck).
Also, 10 other reasons, but that’s the big one.

Q: How do I fully charge BP100 if I don’t drive long, or often enough?
My commute is only 5 minutes long.
I only drive 1-2 times per week.
A: One option is to purchase a “home charger” AC/DC Cigarette Lighter Power Adapter.

Q: Why should I buy an expensive / specialized home charger?
BP100 has a USB Type-C port.
Why can’t I charge BP100 with 65W-100W USB Type-C Laptop charger I already own?
Just like the @Energywell EnergyWell P6 Dash Cam Battery Pack as demonstrated by our friend Pavel from; https://www.youtube.com/@SklepHADRON Channel


A: TBA

Q: Why doesn’t BP100 have an auxiliary charging input for a solar panel to keep it at 100% during daylight hours, so the battery is only discharged during night?
Just like the EnergyWell P6
A: TBA

Q: How do I check the current firmware version installed in BP100, (not shown in VIOFO BATTERY APP)?
Q: How come the current firmware version for BP100 is not listed on the official Viofo website?
A: TBA

Are all the dash cam batteries you tested designed to work with dash cams from a specific manufacturer,
or can they be used with all dash cams on the market?

@Chuck McCoy Can you provide a bit more details about the features only available to Viofo dashcams?
 
If you have both the BP100 and EP100, will both charge at the same time, causing the charge current to double or will it stay the same as with one unit and just take a longer time?
 
Does the USB-C output cut off at the same instant as the 12V output?

Can the USB-C output transmit an ACC signal to a connected dashcam via a USB-C to USB-C cable?

If I wanted to run 2 dashcams from the battery, what is the best way to connect them? Multiple 12V-to-5V adapters spliced to the 12V output, or connect them to a single power adapter?
 
Are all the dash cam batteries you tested designed to work with dash cams from a specific manufacturer,

Short Answer: “All” dash cam battery packs are “universal” and can be used with “any” dash cam.
Long Answer: TBA
Can you provide a bit more details about the features only available to Viofo dashcams?
I spoke to soon, we have to wait for official implementation.
If you have both the BP100 and EP100, will both charge at the same time, causing the charge current to double or will it stay the same as with one unit and just take a longer time?
I’ve often asked myself this question late at night, lying in bed, unable to sleep.
So I filmed BP100 + EP100 charge cycle to observe current / amperage draw, and document how long it takes to fully charge to 100%.


Now I sleep like a baby log.
To answer your question the MAX charging current / amperage is fixed / set, so charging time is increased.
If your next question is; “How long is charging time increased when adding (one) EP100?”
I also have filmed this to get the answer.
But now that we have retail version with official public firmware I want to perform another charge cycle to give you an accurate answer.
Does the USB-C output cut off at the same instant as the 12V output?
I thought I tested this, but I failed.
I will test for you.


Can the USB-C output transmit an ACC signal to a connected dashcam via a USB-C to USB-C cable?
You always ask the best questions, I will test for you.
If I wanted to run 2 dashcams from the battery, what is the best way to connect them? Multiple 12V-to-5V adapters spliced to the 12V output, or connect them to a single power adapter?
I currently have (2) A329S 3CH units running off a single BP100 in my car using two separate HK6 Hardwire Cables.
I’m not sure what you mean by “single power adapter” can you rephrase so I can understand?
As far as “best way to connect 2 cameras to BP100” I’m not sure.

I assumed you could use a pair of HK6 (or an HK6 and the BP100's power converter) connected to the 12V output of the BP100, and it sounds like that is what you are doing.

I wondered if you could connect two dashcams to the 5V output from the BP100's power converter?
 
Hi!
I ordered the BP100 and E100 to replace a B-130A. The hardwire power cable as shown in the BP100 is different from the B-130A. I wanted to know if the B-130A hardwire XT60 will work for the BP100. Or I have to use the 3pin power that comes with the BP100 when it arrived. Thanks a lot.

When you say; "Power Converter" do you mean Hardwire Output Cable?
See attached screenshots.
If so, I don't think that will work due to power starvation.

Welcome to the club.
B-130A hardwire charge cable is 3-PIN XT60 connector.
BP100 hardwire charge cable is 3-PIN MR60 connector.
See attached screenshots.

Since B-130A hardwire charge cable is not compatible, I would make your own "heavy duty" MR60 hardwire charge cable out of 100% OFC pure copper 12AWG wire.
The included hardwire charge cable with BP100 is only 14AWG, (thicker is better).
You only need 12AWG wire for power & ground.
The 3rd wire (ACC / ignition trigger) can be 18AWG-22AWG since it carries no amperage / current.

Thank you for the information and doing the work!
Exactly what I wanted to know. I appreciate it.
I kinda hoped for the current to increase. It would have allowed for short drives with very long recording times.
But on the other hand, both batteries will need to be discharged, which I doubt it will happen if the car is driven at least two times a day to and from work.

Looking forward to your charging time test.
 
I kinda hoped for the current to increase.
"All" dash cam battery packs are pretty much limited to 9 Amp - 11 Amp current draw because of the "unknown" wiring thickness (gauge) behind vehicle's fuse boxes.
RCG530 documented an "early" version of a BBMC PC8 spiking around 13.8 Amps but I think that was fixed with a firmware update.


The included hardwire charging cable for BBMC PC8 is only 16AWG.
The included hardwire charging cable for B-130A is only 14AWG.
If dash cam battery pack manufacturers ever wanted to make a "fast charging" battery pack running around 50 Amps, I think they would need to use 4AWG power wire.
This of course would not be able to run off a piggy back fuse, and would need to go directly to the starter battery just like a traditional car stereo amplifier.
50 Amps would drop the charge time of 70 minutes down to 14 minutes.

Besides the unknown wire gauge behind the fuse box, there's another limitation for all these batteries.
The recommended maximum charging current for standard LFP batteries should not exceed 1C under ideal conditions.
Therefore, a battery with a capacity of about 7.5Ah (7500mAh) should not be charged at more than 7.5A.
In reality, all of them violate the 1C limitation, reaching 9A, which is about 1.2C, and this is under less-than-ideal vehicle conditions, impacting battery longevity.
If @viofo had chosen four 15Ah, 32140 cells (instead of eight 8Ah, 26700 cells), they could have added a third setting for charging directly from the alternator at 15A.
This battery with double the capacity (192 Wh) would have fit in roughly the same case, only 6 mm taller and 24 mm longer.
LFP cells are very inexpensive and account for only a small fraction of the overall battery's cost.

So, imagine a battery of roughly the same size, with a double capacity at 192Wh, capable of charging at 15A, for roughly the same price!

It's a unfortunate that Viofo, despite knowing all the shortcomings of existing batteries, simply produced another clone of the EGEN battery.

And I reject the air transport restrictions excuse – the market is full of high-capacity batteries and power stations.

Yo GPak, I was hoping you’d stop by.
A dash cam battery pack with 192Wh capacity, and 15A max charge rate sounds awesome, I would like that.
1.) How long would that take to charge from 0% to 100%?
2.) How much bigger will the heat sink need to be to dissipate all the extra heat?
The IROAD Power Pack Pro 12 is 160mm x 254mm x 43 mm and "only" 153Wh.
3.) What size AWG (gauge) power & ground wire would that require?
Like 8AWG?
It's a unfortunate that Viofo, despite knowing all the shortcomings of existing batteries, simply produced another clone of the EGEN battery.
At least they didn't use (20) 18650 cells like the EGEN packs, and used only (8) cells. lol
And we got 3-Wire charging input, (built-in relay) with 10 second "soft start".
And I reject the air transport restrictions excuse – the market is full of high-capacity batteries and power stations.
I don’t like the 100Wh limit regulation either, but it’s the reason the IROAD Power Pack Pro 12 (153Wh) has not been "readily available” for sale in USA without “getting creative”.
 
..... A dash cam battery pack with 192Wh capacity, and 15A max charge rate sounds awesome, I would like that.
1.) How long would that take to charge from 0% to 100%?
Short answer:
Charging a 192Wh, 15Ah battery at 15A corresponds to a 1C current, meaning it will charge from 0 to 100% in 1 hour.
In reality, at approximately ±90% charge, the charging current should begin to gradually decrease, so the last ±10% may take a little longer (this time can be adjusted/shortened, but longer is better for the battery's health).

Longer answer:
The real question isn't how long it will take to charge from 0 to 100%, but how fast it is charging?
A 15Ah battery charging at 15A (1C) will charge approximately 15A/9A=1.67 times faster, meaning it will store 1.67 times more Wh of energy in the same amount of time compared to existing batteries.

For example, to store 96Wh, it will take 96Wh/(15A x 12.8V) = 0.5h or just half an hour!
(This corresponds to the full 100% capacity of existing 7.5Ah batteries which takes about 1 hour to charge).
And the cells will be subject to less stress, since we won't exceed 1C.

2.) How much bigger will the heat sink need to be to dissipate all the extra heat?
The IROAD Power Pack Pro 12 is 160mm x 254mm x 43 mm and "only" 153Wh.
If the PCB has a high-quality charge controller integrated, transferring heat to the case via thermal tape, there shouldn't be any issues with heating. The entire aluminum case acts as a "giant" heatsink.

The dimensions of my DIY 192Wh, 15Ah LFP battery using 4 x 32140 cells are 54 x 145 x 250 mm.
It is a modular design that includes individual components such as a large 30A automotive time delay relay, a 20A charge controller, a 40A BMS, a dual-input automatic transfer switch (ATS) for bypass, and Voltmeter/SOC indicator.
All connected by a network of 12 AWG and 18 AWG wires.
The components were optimized only based on what was available off-the-shelf.

A clean-sheet design allows most of these components to be combined into a single PCB, reducing the case size.

In terms of cell configuration, the 8 x 26700 cell pack measures 26 x 104 x 140 mm, while the 4 x 32140 cell pack measures 32 x 128 x 140 mm. (only 6mm taller and 24mm wider).

3.) What size AWG (gauge) power & ground wire would that require?
Like 8AWG?
Depends on wire length.
According to online calculators and assuming copper wires and "standard" 3% voltage drop:
Up to 8 ft – 14AWG
9 to 14 ft– 12AWG
15 to 23 ft – 10AWG

...I don’t like the 100Wh limit regulation either, but it’s the reason the IROAD Power Pack Pro 12 (153Wh) has not been "readily available” for sale in USA without “getting creative”.
Amazon alone has hundreds of batteries of all types and sizes, available with 2-3-day delivery.
How do they all get here? I'm guessing by sea and land; it's much cheaper.
As for service, for a market as large as the US or EU, they should have a service center right here, and as far as I know, Viofo does.

BTW, the Irod has a 76.8Wh, 6Ah battery, but it's also not sold in the US. (there must be some other reasons)
And I believe Canada and the EU have very similar restrictions on batteries and air transport.


Chuck, you make me type a lot. 🙂

Can the USB-C output transmit an ACC signal to a connected dashcam via a USB-C to USB-C cable?

In the manual, it says this about the type C port:

Port for powering a dash cam(parking mode
not supported)

So I'm guessing it doesn't pass through the ACC signal required for parking mode, but let's wait to see the testing 🙂

If @viofo had chosen four 15Ah, 32140 cells (instead of eight 8Ah, 26700 cells), they could have added a third setting for charging directly from the alternator at 15A.
This battery with double the capacity (192 Wh) would have fit in roughly the same case, only 6 mm taller and 24 mm longer.
LFP cells are very inexpensive and account for only a small fraction of the overall battery's cost.

That's interesting, I still assumed the cells were a large percentage of the cost, I guess this has changed somewhat as EV's are starting to use LFP batteries now.

In 2021, I bought a 18Ah battery with BMS for about £120, I'm seeing 100ah batteries for around the same price now. (Obviously it's not quite the same, as I am looking at full batteries with BMS, not individual cells)
 
A few questions, the "Hardware output cable" that comes with the battery, is this just a HK-6 with a connector or is it another complete new hardwire cable?

bp100.webp


Also, what is the reason for battery packs having 3 wire charging? My cellink batteries just have 2 wires as you just have ACC off/on for charging the battery.

I assume you are going to test cold weather charging (It was -2 degree C this morning which made me think about it)
 
A few questions, the "Hardware output cable" that comes with the battery, is this just a HK-6 with a connector or is it another complete new hardwire cable?

I asked this same question earlier--it is apparently just a 12v to 5v converter but without the voltage display feature of the HK6 and it has no low voltage cutoff so most of the battery capacity can be used. As someone noted, you could instead use a HK6 in its place especially if you already have one, but it would need to be the special no LVC version for the best battery experience.
