Is $197 a good price for this battery?

It is well below what 200Ah LiFePO4 batteries usually cost, and it is the best new price among the two stores listing it as of November 5, 2026. Check that the eBay listing is new stock with the Renogy warranty before buying.

Can I use it to start my engine?

No. It has no CCA rating and is built for deep-cycle house power, not cranking. Keep a separate starting battery for engines.

Will it work with my existing charger?

Only with a charger that has a lithium LiFePO4 profile. A lead-acid charger will not fully charge it and may shorten its life.

How many batteries do I need for a 12V system?

One battery gives 12V and 200Ah, about 2,560Wh. For 24V or 48V systems, wire two or four in series, and use identical batteries bought together.

What comes in the box?

One 12V 200Ah LiFePO4 battery, two long terminal bolts, terminal bolts and a user manual. A shunt for remote monitoring is sold separately.

Prices on this battery move with sales events and stock. The $197 eBay price as of November 5, 2026 is the low point seen recently, so compare against the other listing before waiting.
