Our take on the Marine Battery Charger, 2-Bank 5A 12V Onboard

This is a two-bank onboard charger that puts up to 5A and about 90W into each of two 12V batteries at once, using three-stage charging. It handles lead-acid, LiFePO4 and NCM packs, so it suits boats, RVs and trailers that mix battery types. The aluminum housing is rated IP68 and works from -4°F to 185°F, which is tougher sealing than most open-frame onboard chargers offer. Long 5.74 ft AC and DC cables ease mounting away from the batteries.

Questions and answers

Can it charge lithium and lead-acid batteries at the same time?
Yes. Each bank charges independently, and the three-stage profile supports lead-acid, LiFePO4 and NCM. Check that each battery's chemistry matches what the charger is set for.
Is 5A per bank enough for a large boat battery?
It will charge, but slowly. A 100Ah bank drained halfway needs many hours at 5A. For big house banks, a higher-amp charger is a better fit.
Can it stay installed on the boat permanently?
Yes, it is built as an onboard charger with an IP68 aluminum housing. Mount it securely and keep the cable connections dry.
What comes in the box?
The charger with its 5.74 ft AC and DC cables. Mounting hardware and battery clamps or ring terminals are not specified, so confirm before installing.
Does it work in freezing or very hot conditions?
The rated range is -4°F to 185°F. Charging a frozen lead-acid battery is still a bad idea, so let it warm up first.
