The product specs for the CALB CA series cells specificially allows charging between 0C and 45C and discharging between -20C and 55C. I couldn't find a spec sheet for the SE series cells but I don't imagine it would be much different. -20C is -4F btw.
Because it gets below 0C fairly often here I put mine in heated insulated battery boxes. --Rick On 01/06/2014 07:20 AM, Mark Hanson wrote: > Hi, I have 36ea CALB 130ah LiFePO4 in my www.evalbum.com/4346 Ghia > and was curious if it's bad for the batteries (I read) to charge/use > below freezing.
