I have two chargers. One is 4A and the other is 7A. I have a freshly made 12s3p 40T pack with a bypassed 13s daly BMS with the last pins shorted. The BMS is rated at 8A.
The 4A charger will charge my board every time no problem. idk the brand,I borrowed it from @Brently
The 7A charger will not charge my board. This one I have 4 of them and all of them behave the same. See the video below.
Also, I remade the xt60 to barrel adapter I had; just to be sure it wasn’t something I fucked up.
This is the BMS I used.
TIA for the help guys
