Our take on the DJLBERMPW 12V 200Ah LiFePO4 Lithium RV Deep Cycle Battery 2560Wh

A 12.8V 200Ah lithium iron phosphate deep-cycle battery rated at 2560Wh, aimed at RV house banks, off-grid solar and trolling motors. LiFePO4 gives you roughly twice the usable capacity of a lead-acid battery of the same rating and far more charge cycles. At $197 at eBay as of November 5, 2026, it sits well below what mainstream 200Ah LiFePO4 batteries usually cost, so the price is the main draw. The catch is a low-profile brand with little independent testing behind it.

Questions and answers

Is $197 a good price for a 200Ah LiFePO4 battery?
Yes. Most name-brand 200Ah LiFePO4 batteries sell for well over $400. At $197 at eBay as of November 5, 2026, this is near the bottom of the market, which reflects the unknown brand.
Can I use it to replace a lead-acid RV battery?
Usually yes. It is a 12.8V drop-in for a 12V deep-cycle bank, and it weighs much less. Check that your charger has a lithium profile, since lead-acid charging profiles can stop short of a full charge.
Can I connect several in series or parallel?
Most 12V LiFePO4 batteries allow up to four in series for 48V or several in parallel for more capacity. Confirm the limit with the seller before wiring a bank, because the BMS rating matters.
How many charge cycles does it last?
LiFePO4 cells are typically rated for 3,000 to 5,000 cycles to 80% capacity. This brand does not publish a tested figure, so treat the claim with caution.
Does it have low-temperature charging protection?
That is not confirmed for this model. Charging LiFePO4 below freezing damages it, so if you camp in cold weather, verify the BMS has a low-temp cutoff or disconnect the charger.
What comes in the box?
Expect the battery alone, with top-post terminals. A charger and mounting hardware are generally not included.
Where is the DJLBERMPW 12V 200Ah LiFePO4 Lithium RV Deep Cycle Battery 2560Wh cheapest?
At Amazon, for $299.99, as of our latest check.
Where can I buy the DJLBERMPW 12V 200Ah LiFePO4 Lithium RV Deep Cycle Battery 2560Wh?
