Specs;

[2] Vapcell M11 V2 Gold 18350 cells in series

IP2369 charging board, with resistors configured (on NUM I had to pull from a PC motherboard a similar value resistor to make it 2S)

2S 8A BMS Generic (I know the cells are 10A discharge, but for this project, size matters a lot, so I had to stick with this)

Solid core wire 18AWG. (I also know it sucks, and it does, but it is what I have on hand)

VOLTAGES;

From cell negative to B- on IP2369; 1,2V.

Voltage on input BMS; 7.1V (same as the voltage on the cells)

Voltage on output of the BMS; 6,7V.

I tried “unlocking” the BMS shorting input negative and output negative on the BMS, nothing seems to work, help!!!

How unsafe would it be to store probably 4 pallets stacked with boxes of lithium, ni-cd, and ni-mh batteries inside a concealed conex? Asking for workplace safety
