Hi,

My battery is connected to a 3 pole led switch. From that, i want to power accessories, for e.g. a light.
But the BMS is going on sleep mode after some time of inactivity, so i have 0 voltage on the terminals, even if i turn on the switch.
How do you wake up the bms for a battery power usage ? I'm not talking about charging, it will automattically wake up.

Thank you.
 
BMS should wake up with a load on the battery or a charge on the battery. There are also a couple pins on the BMS you can short to wake it up as well.

I tried with a led or a heating resistance. The BMS doesn't want to wake up.
It indicate 0.04v on the P- and positive.
 
You might post this in the BMS section. Likely someone has seen it before.
 
Bridge these terminals
