Is $197 a good price for this battery?

At $197 at eBay as of November 5, 2026, it is low for a 200Ah LiFePO4 battery. Confirm the listing is the 200Ah model before you buy.

How long will it last?

ExpertPower rates it at 4000 to 7000 cycles, which is years of daily use in most setups. Real life depends on depth of discharge and temperature.

Can I use it as an RV house battery?

Yes. It is a 12V deep-cycle battery suited to RV house banks, solar storage and trolling motors.

What charger do I need?

Use a charger with a LiFePO4 profile. A lead-acid charger can leave it undercharged or overcharge it.

Can it be charged in freezing weather?

Only if the model has low-temperature charge protection. Otherwise, do not charge it below freezing.

Typically just the battery. Check the listing for terminal hardware and a charger, which are usually sold separately.

Our take on the ExpertPower EP12200 PRO 12V 200Ah LiFePO4 Battery

The ExpertPower EP12200 PRO is a 12V 200Ah lithium iron phosphate (LiFePO4) deep-cycle battery built for solar storage, RV house banks, trolling motors and backup power. LiFePO4 gives it a long rated cycle life and much less weight than a comparable lead-acid bank. The best new price is $197 at eBay as of November 5, 2026, with 2 stores listing it new. That is low for a 200Ah LiFePO4 battery, so confirm the listing is the 200Ah model and not a smaller EP12200 variant before buying.
