BMS with low/high temp protection

[MrNatural22]

Trying to get recommendations for 100amp common or separate port BMSs with both high and low protection. Can’t seem to find any.

Humm must be unheard of or non existent.

What about Tiny BMS with external contactor(s)?

Never seen one . Use a temperature sensor board $3 to drive a 100 Amp capable relay which is in the battery negative line after the BMS maybe . Some of them you can set high and low cutoffs but maybe you will need two separate. I'd go for Mosfets rather than relays on the temp board.

Maybe a latching relay would suite best. Normally on but switched off by a pulse when temp below 0 C back on when temp comes up . I use one of them to control my inverter fan and it works great.
