End Stage Battery Setup (1200 watt hours, 20 minute quick charge)

[halomstr]

So I thought I'd in brief share my hardwire setup:
-Orion TR smart 12-12-30
-6 Awg pure copper wire
-Everything 100 amp fused with midi fuses
-Everything hammer crimped with copper lugs
-LiTime 100Ah self-heating lifepo4 smart battery
-Custom 3d printed terminal protector / orion holder / fan support

The Orion has a common ground so you can use the acc power on signal to the camera without a relay.

The battery is automatically self heating so it maintains temperature in cold weather and charges instantly.

With the added cooling, the Orion consistently puts out 35 amps / 460 ish watts into the battery.

An AudioControl a800.1 amplifier for my subwoofer is connected to prevent additional strain on the alternator. A separate 120 mm fan with fan speed controller provides adjustable cooling that is wired to acc power.

This is all connected to a hardwired viofo a229 pro with an upgraded ultra wide interior camera.

All said, it should record about 7 days in warm weather and a little less in cold. It should also charge to full in about 20 minutes after 24 hours of camera use.

I also have an additional hardwired car outlet connected to the battery for an always on extra power socket that supports up to 200 watts (it is 14 awg wiring).

It was expensive, but I don't think you could get better for auxiliary power.

Very impressive setup!
High-quality components and first-class workmanship.
The Self-heating is must for LFP battery to operate year-round in regions with cold winters.

Of course, in absolute terms it is a bit expensive - at current prices, the cost is likely around $550.
However, if you compare the price per watt-hour, this solution is actually six (6) times !!! cheaper than the average dedicated dashcam battery.

For your battery:
$550 / 1280 Wh = $0.43 per Wh

For the average specialized battery:
$250 / 96 Wh = $2.60 per Wh

The setup has honestly been perfect. Lasts forever, accessory power, doesn't care about the temperature. It is also definitely smaller than 5x 96wh batteries and I am pretty sure those aren't self heating.

Correct - none of the dedicated batteries are self heating.
And more than 13 dedicated batteries with a capacity of 96 Wh each will be required to achieve a total capacity of 1280 Wh. 🙂

For this reason I have built couple of LTO (Lithium Titanate) dedicated batteries, which can be charged at high C-rate even in deep freezing conditions.
(You can find the corresponding thread dedicated to LTO right here on DCT).
