Hello from California!
I am new to making banks! Ihave some NCR18650B cells, I wantto wire them up in a 3S4P configuration for my bot. They are 3.4ah @ 3.7v nominal cells. I read that if youuse one ofthese battery protection boardsyou'll be able to safely balance charge the bank, so I picked one of them up. I also have a hobby charge for the turnigy cells I was using before.
From what I understand, you have balance leads from the pack, to the charger so the chargerreadsthevoltage of the individual cells and thenappliescurrent from the 2 main leads based on the reading, then whennear full,it will stop current flow to main leads, andput current to thebalance leads to top them alloff equally.I understand parallel and series connections, when it comes down to wiring with this board, I'm a bit confused.
On a side note, could one use a desktop PSU to charge multiple packs? I'm aiming to charge many packs at once, as cheaply as possible lol.
Is this accurate?Do I have the right approach so far?Can anyone show me how to wire this all upcorrectly? Thanks!
I did my best with what I had. My solder point were very poor but I don't think it affected the battery, it feels like incorrect wiringor bad BMS.I'm sure its a trivial mistake but I failed, send help!xD
My cells were all at 3.50v, my pack at my main hot and ground read 3.5v as with all the rails on the pack... The when it was assembled the pack slowly became really hot, until it got to the point where I turned it off.
