LOOK INSIDE 72V UPP Battery 19.2ah Triangle

I disassemble my 72v 19.2ah UnitPackPower battery that i purchased on Amazon a year ago https://amzn.to/45w8FPj , it is a 20s 4p battery with INR21700 M48A cells from LG. They are 4800mah cells with a discharge rating of 7A continuous, 17A peak. In 4p, the battery should be able to do 28A continuous, 67A peak. It has a 60A BMS. The parallel groups are in spot welded together with nickel (?) plates. The discharge wires are 12awg on the negative and 14awg on the positive. The foam inside the battery was not all placed in an effective position. If you mount this battery upside down, or with the back of the triangle facing down, you may be smushing your BMS with the weight of all the cells in the battery. I look at the solder joints on the terminals of the battery. I put the foam back in a spot that will better protect the cells.
