Some battery makers are now building self heating LiFeO4 batteries.
No they don’t use their own amp hours to heat. The batteries can deliver energy down to -20C battery temp.
They use energy from the charging source to warm the cells. Then they begin to charge.
Lithium batteries can accept charge at very high rates.
This is why a small generator or engine alternator charging is probably step one in a lithium system then do the solar spend to round out the system, especially if you camp in winter, forest, shade, or rainy lands.
