Low temp CFET and DFET lockout

[Jim Niemann]

I have both a SBMS 120 and 100.  We are planning on storing our RV in cold temps for the 1st time and I am wondering if the low temp lockout will auto-reset when temps warm above low limit.

Jim,

Yes if the battery temperature gets back to normal temperature the charging and discharging will resume.

But if battery temperature gets very low it could take days or multiple weeks before battery can get back to normal operating temperature.

If you are just storing the RV and not using it you could disconnect everything including the SBMS and then reconnect when you need it.

Battery has no problem being below freezing if is just in storage and not used.
