Seems like a good charger well made heavy and the hardware was nice. It charged up 1 gel and 1 led acid all the way up and I liked the green lights on it that show progress of the charge. Smaller than the minn Kota it replaced after 15plus years of use. Price I think is reasonable so if it lasts half as long it will be a good buy.

This one is ok so far. The first one I got went down after 3 or 4 months. Same unit difference name. Though I was getting a different brand to try, got fooled. Misleading for sure.

This is a very good all in one charger to keep two batteries charged at the same time. I use it for my vehicle batteries charged which are not in use It’s pretty durable and easy to operate The SAE adapter included in the kit makes life easy for charging. multiple selection for different 12v battery types

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 an edited review. The first charger I bought was junk. Didn’t work at all. This company contacted me after my review and asked for a second chance. I gave them one. They shipped me a new unit free of charge. The new unit is working great. No issues and is working as expected. I’m giving 3 stars bc I’ve only used it twice. But so far, the replacement is working as advertised. Customer survive with this company is pretty great.

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.
