why i call Li fussy
Hi all, This doesn't cover all the concerns for me, but it does show at least some of them: https://youtu.be/_PgthByAYz4

Not trying to pick it apart, just not clear on the sequence. The inverter/charger has its 12v and starts charging when it gets the 120v and charger enabled. Ok. Charging amps are shunted to the heater, ok.
But now it says (when the shunting happens, same signal?) the BMS is disconnected from the cells. Or does it disconnect from seeing a certain cold temperature? Badly written blurb.
So no battery 12v to run the inverter/charger or the rig. Doug posted about that when I thought (wrongly) it worked like a converter, and could supply 12v with no battery. Nope, it needs 12v from somewhere --the battery usually--to operate before it can can supply 12v to the battery
That blurb is badly written, so maybe the BMS does not disconnect?
If that is how it works, then those with inverter/chargers would choose the heating pad method instead of getting these LFPs with built-in heaters, but those with converters would be able to use this type of heating.
