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

The KFFKFF is a 2-bank onboard marine charger that puts 5A into each 12V bank. It handles lithium (LFP and NCM) and lead-acid batteries and can start charging a bank that has been drained to 0V. A sealed metal case with IP68 rating and a -4°F to 185°F operating range sets it apart from open-frame chargers that need a dry locker. It suits boat owners who leave the charger wired in and want a set-and-forget unit for two banks, though at 5A per bank it is a maintainer rather than a fast bulk charger.

Questions and answers

Will it charge lithium and lead-acid batteries?
Yes. It supports LFP, NCM and lead-acid batteries, so one charger can serve a lithium house bank and a lead-acid start battery.
Can it revive a fully drained battery?
It is built to charge from 0V, so a bank that has been run flat can be brought back rather than replaced.
How fast does it charge?
Each of the two banks gets 5A. That is fine for maintaining and topping up, but a large deeply discharged bank will take many hours.
Is it safe in a wet bilge or engine compartment?
The sealed metal housing is rated IP68 for water, dust and salt exposure, and it is rated to run from -4°F to 185°F.
Does it protect against overheating?
Yes. It has safeguards against overheating, severe weather and vibration, and its multi-stage charging holds current and voltage steady.
