Hello, I just decided to take apart my brand new BlackVue B-124 and post some internal pictures as I couldn't find any. I found out a few things from doing this. On the picture of the circuit board the board name is NEO6 REV-G.
I didn't separate the batteries from the upper part of the case as it used some strong adhesive tape and I didn't want to ruin it. With it being attached, it helps a bit in thermal conduction. Building and 3D printing an extension would only require a 4s BMS, some decent gauge wire and a female XT60 connector. You can add whatever fuses that you want to make things more safe is you wish. Make sure that you get the batteries in groups of 4.
To open the device, the labels on both sides should be carefully removed. Doing this will expose four Phillips head screws on each side. This also reveals a hidden micro USB port. ( I didn't connect anything to it.)
Removing all screws on both sides will allow the 2-piece aluminum case to separate from the plastic side panels.
Here are the seperated case pieces
The B-124 uses sixteen IFR18650EC LiFePO4 3.2v 1.5Ah batteries in a 4s4p configuration. Four in series ( for the 12.8 volt rating) multiplied by four in parallel (for the 6,000mAh rating) Since power = Voltage x Current you get the rating of 76.8Wh
Notice that the boards name is NEO6 REV-G. The solder points located to the top labeled B+1 and B-1 are the positive and main positive and negative points which connect to the beginning and end of the battery series. The points to the bottom labeled BM1 and BM2 are balance and monitor the difference in voltage between the four series of batteries. Batteries balance themselves out in parallel but with sensitive lithium types, it is strongly recommended to have some type of Battery Management System.
Just a random picture of the micro USB port.
