Our take on the Dumfume 12V 100Ah Mini Max Deep Cycle Rechargeable LiFePO4 Battery

The Dumfume 12V 100Ah Mini Max is a lithium iron phosphate deep cycle battery built for RVs, camping and off-grid solar. Its compact case packs the same 100Ah capacity as standard-size 12V LiFePO4 batteries, so it fits tighter battery boxes and compartments. LiFePO4 chemistry gives it a longer cycle life and lighter weight than a comparable lead-acid battery. It suits owners replacing group-size lead-acid batteries or adding a second house battery, though buyers should confirm the charge profile of their existing charger or solar controller supports lithium.

Questions and answers

Is this battery a drop-in replacement for a lead-acid battery?
It fits many group-size battery boxes and uses the same 12V nominal output, but it needs a charger or solar controller with a lithium charge profile. Lead-acid chargers can undercharge it or push it too hard.
Can it be used in an RV or camper?
Yes. The deep cycle design is aimed at RV house power, camping and off-grid solar. Check that your converter and solar controller have a LiFePO4 setting before installing.
How does it compare with a standard-size 100Ah LiFePO4 battery?
The Mini Max case is smaller, which helps in tight compartments. Capacity and chemistry are the same class as common 100Ah LiFePO4 batteries, so runtime is comparable.
Can I charge it below freezing?
LiFePO4 batteries generally should not be charged below freezing. Confirm the battery's temperature limits before charging in cold conditions, and look for a heated model if you camp in winter.
Can I wire two of these in parallel?
Parallel connection of same-model 12V batteries is common for adding capacity, but follow the manufacturer's wiring and charging limits. Series connection for 24V or 48V should only be done if the maker supports it.
What is in the box?
The battery itself. Terminals, mounting hardware and chargers are usually sold separately, so check what your setup needs before ordering.
Where is the Dumfume 12V 100Ah Mini Max Deep Cycle Rechargeable LiFePO4 Battery cheapest?
