I recently purchased the Bank Marine Battery Charger, a 12V 30A smart waterproof onboard charger compatible with SLA, AGM, Lithium (LiFePO4), calcium, and deep-cycle batteries. Its versatility and waterproof design make it ideal for marine use. The installation process was straightforward, and the user-friendly interface offers multiple charging modes that optimize performance based on battery type. However, it may not effectively revive older batteries that have significantly degraded. I really like this charger; I truly needed something like this. When I needed a quick solution, it was incredibly helpful. Its smart technology also includes a maintenance mode to prolong battery life by preventing overcharging.

I have a mix of two lithium batteries wired in series to my trolling motor and a lead acid cranking battery. I needed a new 3 bank charger that could support LiFePO4 lithium batteries and a lead battery independently. The first time I charged the batteries with this charger I got a little nervous because I left them connected long after the charge was complete and the LEDs on the charger were red. Later I realized the cause was a breaker was reset in the electrical panel. The power disruption caused the red LEDs ( my boat fully charged and the batteries and charger were fine). Since then I moved the charging cord to a clean circuit to avoid power disruptions and no more issues — a fully charged battery always produces green LEDs. I don’t know if this is a problem, but it seems strange that when I remove power from the charger after the batteries are completely charged, the bank responsible for charging my lead acid cranking battery doesn’t turn off. It seems like the battery is back feeding power to that bank at least enough to keep the green LEDs lit for days. The quality of the charger has been great after about 15 charges.

This is really sturdy unit. I installed it on my 19' aluminum fishing boat to charge 3 12v lithium batteries. The charger works fast and delivers 10amps to each battery. It does not have a percentage readout but it has 5 lights that represent 20% each and they flash between the 2 so 60-80% would flash between 3rd and 4th light etc. This unit is larger than the picture shows but the written description is accurate. All in all it's a great unit and pleased with its performance.

Revised review. Seller graciously reached out to me and replaced the failed unit. So far it is performing well. Didn't give 5 stars because the unit charges 7 amps below the stated amperage. Does a very good job for the price.

Our father in law is always complaining about his batteries on his boat going dead! This has solved all of his issues! Its easy to use, is compact and takes up very little space, and seems to be of good quality. I was able to catch this on sale as well so its a great value for the price.
