LiFePO4 house battery, 200Ah
Dumfume 12V 200Ah LiFePO4 Specs and Sizing
Researched from published standards and manufacturer specifications. Updated .
Quick answer
This is a specification sheet rather than a review. Every figure below comes from the manufacturer listing, and we do not test products in person. What this page adds is context: what these numbers mean for an RV system, and what else you need to buy alongside it.
Best for: A battery that lives somewhere it can get damp.

What does this component need alongside it?
A battery is only as good as what charges it. A lithium pack needs a converter, solar controller and DC-DC charger that all carry a genuine lithium profile, plus a shunt monitor to read state of charge, correct cable sizing and a fuse at the positive terminal.

Yeagulch 12V 200Ah LiFePO4
$316.59A 200A BMS is the spec that matters here, because a 2000W inverter can pull close to 200A from a 12V bank at full load.
Best for: A single-battery bank that has to run a 2000W inverter.

- What is the Dumfume 12V 200Ah LiFePO4 best for?
- A battery that lives somewhere it can get damp. Published 200A BMS and an IP65 rating on the case, which matters in an underbelly or pass-through compartment. Confirm the current specification on the listing before buying, because manufacturers revise these products without changing the model name.
- Is the Dumfume 12V 200Ah LiFePO4 suitable for a lithium system?
- Yes. This component either is a LiFePO4 battery or carries a genuine lithium charge profile, which is the specification that matters. A charger without a lithium profile will not bring a LiFePO4 pack to full charge.
- What size cable and fuse does it need?
- That depends on the current it carries and the length of the run, not on the component itself. Work out the current from its rating, then size the conductor for both ampacity and voltage drop with the wire gauge calculator, and fuse it at 125 percent of the continuous load rounded up to the next standard rating.
Lithium safety. A LiFePO4 bank needs a charger with a genuine lithium profile, and that means the converter, the solar controller and any DC-DC charger all have to be set correctly. A stock lead-acid converter will never bring a lithium pack to full. Charging a lithium battery below freezing damages the cells permanently, so the pack needs either a low temperature charge cutoff in its BMS or a self-heating design if you camp in the cold.
