Smart bms cl 12/100 with non Victron lithium batteries

  • I've connected my Smart BMS Cl 12/100 into my system with my non Victron lithiums, my non Victron bms is connected to the remote switch to stop overvoltage.

The starter battery is above the voltage needed but I'm still not getting any charge into the battery. I'm getting an alert saying that undervoltage protection is activated even though its registering the Lithiums and starter above the cut off limits?

Is this because I'm using a none victron battery and the 2 bms cable aren't connected?

If so is there a workaround?

I would have used the bms 12-200 but my alternators neg goes through the engine.

All Victron BMS are only designed to work with Victron batteries.
I don't think you can get it to work without a battery connected to the BMS connectors.

I believe the bms 12/200 does as its used to regulate the output of the alternator.

What feed does the bms need from the victron battery to make it work? Is there a work around?
