Why we picked this deal
Redodo self-heating 12V 100Ah battery charges in the cold, now $265.99
Two 100W heating pads switch on automatically when the battery drops below 32°F and stop at 41°F, then charging resumes. That makes this LiFePO4 battery a fit for RVs, boats and solar setups that see freezing nights.
One battery is $265.99, down from $559.99.
