I'm building a 4S 12 Volt battery with EVE 280 AHr cells. I plan to heat, and possibly cool them inside a Group 27 Marine Battery Case. I'll be replacing 4 6-volt, 150 AHr AGM batteries. While I was considering options for temp sensing for the heating pads in the bottom of the battery case, I...

Understood. I am not looking for temp compensation charging, I am looking to turn off all charging below a specified temp.

I plan on using that BMS, but I want to stop charging before the BMS has to do it. The way I look at it, if the BMS has to shut down on over voltage, under voltage, low temp, high current, your design was poor, or a component in the design failed. To me, the BMS is a last lifeline before...

I believe, after further study, that ONLY MPPT controller can shut down on low temperatures. It appears that Victron as specifically addressed this issue, and has prohibited (in software) that function in MultiPlus type devices, believing that should only be handled at the cell level. Curious...

I must not have been clear. I want to use the Victron temp sensor to control the Victron units. I have 180 Amp charging capacity (between the MultiPlus and 2) 100/50 MPPT Controllers. It's my understanding that Victron uses battery temp as an input to maximize charging. I will have separate...
