Thanks High. That explains it since in theory if the multiple batteries were in parallel they would have to be basically at the same potential and would not trigger the heat circuit Makes sense now..
I am trying to figure out how it works when you have self heating batteries in parallel. The way I understand it is that a self heating battery will only use incoming "charging current" to heat the battery if it is below the safe temperature to charge. So lets say you have 2 of these batteries...
In Will's latest video he suggests using a 48volt rack mount battery combined with a 48 volt all in one inverter for RV use. This pretty much checks every box for me except how do I charge via alternator while driving ?
