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 three battery setup on my fishing boat and this does a really solid job charging them all up. It was very easy to set up with all of them and it allows me to quickly plug it in before heading to bed and the batteries are full for me in the morning.

Does not come with a way to permanently secure leads to battery posts. Only comes with spring clamps. You have to create your own way to connect to batteries in boat

Everything about this charger Is on 10...I chose this on board because I switched to Lithium batteries and the charger o had, of course want rated for lithium so.....But, I needed a 3 bank charger that could charge every battery type.(My cranking battery is lead acid)...so, it fit what I needed...I looked at the other expensive one but, I didn't want to pay that much so, I have this one a shot...it's everything I expected...Works charges, maintains my batteries very well

These came in and look great. Have not had a chance to use but wires and battery box look sturdy. Does not look like a cheap charger. Looking forward to using.
