- Which is better for an RV house battery?
- The Dynesspower, because its 200A continuous discharge and 14.4V charge profile are published and match typical RV inverter and converter setups. The DJLBERMPW may work, but confirm its BMS current limit with the seller before buying.
- Are they the same battery?
- They share the same 12.8V, 200Ah, 2560Wh ratings and the same $197.00 eBay price as of November 5, 2026. The Dynesspower publishes a full spec sheet; the DJLBERMPW does not, so treat them as similar cells with different documentation.
- Which lasts longer?
- Neither listing gives cycle life, so there is no basis to pick one on longevity. LiFePO4 packs of this class typically run 3,000–5,000 cycles, but ask each seller for a cycle count at a stated depth of discharge.
- Is one worth the extra?
- There is no extra: both are $197.00 at eBay as of November 5, 2026. At the same price the Dynesspower's published ratings make it the safer buy.
- Can I use either for a trolling motor?
- The Dynesspower's 200A continuous rating covers most 12V trolling motors. The DJLBERMPW does not state a continuous current, so verify it can handle your motor's draw before relying on it.
- Do the dimensions matter?
- Yes. The Dynesspower is about 20.9×8.1×8.5 in. The DJLBERMPW's listed 15.70×20.47×14.50 in is far too large for a 200Ah pack, so measure your bay and confirm actual size with the seller.
