I have assembled my first battery and connected it with the balancer cables. Now I just wanted to charge the battery.
How do I know, if my bms is working on a preloaded battery. I preloaded every cell before point welding, thats why my 10s battery is preloaded.
my setup: 10s4p samsung 30q battery
bms: 10s 20A bms for charge only
On my bms is no signal LED or comparable.
Are there any voltages that I can measure during charging that tell me BMS is doing its job correctly?
And secondly, do i connected the BMS correctly for charge-only?
The wires are only for testing. Later i will be using for battery connections 8-10 awg but for charge port you don’t need such big wires if the voltage drop is lower than 3%.
This diagram would be correct for a BMS for discharging, too where C- = charge and discharge (same port). But in your case that’s a wrong sketch, give me some minutes to correct it.
