Can the SOK 206Ah run in cold weather?

Yes. The built-in heater pad lets it operate down to -4°F, and the BMS blocks charging until cells are warm enough.

Can I wire several together for 48V?

Yes. Units can be connected in series up to 48V systems and in parallel for more capacity, within the BMS limits.

Can the BMS or cells be replaced?

Yes. The detachable cover gives access to the BMS and cells, so either can be swapped out.

What charger should I use?

Use a LiFePO4-compatible charger set to the battery's charge profile; the BMS handles cell balancing and cutoff.

Is it good for an RV house battery?

It suits RV house power well thanks to the capacity and heater, but check compartment space and weight before buying.
