Default Re: Detachable BMS; should it work?

PStechPaul,
cells are cool, no heat at all. We are charging at modest rates, 6 amps for 60ah cells.
We are thinking about upgrading the wires. Right now we use thick wires for + & -, and thin wires for each individual cell conected to the BMS. I don't have the size number here, unfortunately. Lenght is about 2 feet (maybe a bit more) from cell to BMS conection.

I don't have much info on the BMS, we bought it at evassemble. There a few specs there:

major,
yes, this one or a clone. We bought it from Ali-express.
Connection is very unreliable, we are going to solder a new one on it soon.

skooler,
hi Mike, yep the project is moving fast this summer, thanks.
The Sinopolys are behaving well (granted, we are not pushing them hard yet) and the old motor seems to cope well with the load, but the little Kelly KIM we bought is probably too weak for it.
Well, that's life. As I told you, our budget was small
I should post a video soon, on AEVA.

What you say about the wiring sounds right, so I guess we will have to do some re-wiring there. However, there is still a lot of work to do on the rest of the vehicle so I guess we will check the BMS later. I should have calculated the voltage fall looking at amsp anf the wire sizes before connecting all the mess!
