I do wonder if these self heated batteries only allow external power for heating.
The ones I've found online draw from the battery, and have no provision for an external energy source.
PT, this a typical blurb for a "cold weather" drop-in LFP:
"In cold temperatures, the BMS ( battery management system) disconnects from the cells to protect your battery. Prior to charging, the built-in heating systems draw power from the charger in order to heat up the battery."
Time2roll would set his BMS to allow charging at X temp, and also set his heat pad Tstat relay temp to keep them above that BMS set charging temp.
No idea where his charging rate setting might be for cooler temps, if he even does that. Once set up and camping proven after any adjustments, it should be easy after that to just go camping no worries.
