Do you have BMS for these CATL 280Ah LiFePO4 Prismatic cells?

These cells do not contain BMS, but they contain free bus bars and bolts. If you need the BMS, you can browse our BMS products page

I will be housing these in my current battery compartment under my RV stairs. this is an open-air area. what do you recommend for housing these cells?

Be sure they are mounted in an area where the temperature will be between 32℉ and 100 ℉.

Can these LiFePO4 Prismatic batteries be charged in a series or does each cell need to be regulated at 3.65?

Hello, you can charge in series, but you’d better use a lithium iron phosphate special charger.

The charging temperature is shown in the specs as -20℃ to +60℃. Can these cells actually be charged when below freezing without damage?

No. They can be used (ie discharged) below freezing, but not charged. A good DMS (highly recommended) should prevent this.

Are these LiFePO4 Prismatic batteries stable enough that you could put them into a wood case the same as you would in an already plastic-housed battery?

Hello, they are stable, we protect the items with thick bubble wrap, and the product will arrive at your address in perfect condition.
