    • Great 3 bank charger
Needed to recharge my batteries in my bass boat. Set up easy. Right size. Worked great.

    • Exactly as promised. Elegant design and execution.
This is a very elegant, attractive piece of equipment. Installation instructions are clear and easy to follow. This is a great piece of equipment for someone tired to replacing batteries every 1 to 2 years. Reconditioning function saved two out of two batteries for me, more than covering the cost for this equipment in the first 48 hours in my boat. I added the permanent shore power electrical plug in accessory and am very pleased with the ease of use and quality of life increase it brings. Fast delivery, exactly as estimated. This is and easy install for the DIY individuals out there. Elegant and very efficient equipment. You wont be disappointed to have one of these in your boat. ... show more

    • Easy install
Works great. Hooked up to trolling motor batteries. Charged quickly and easily installed.

    • Great charger
I installed this charger so I could charge different types of batteries. I’m using a 12V AGM dual purpose for my starter battery and to run graphs. I’m using lithium batteries to run trolling motor. I like being about to charge different types of batteries at the same time using the same charger. I wired them to each set of batteries and they were all charged in very little time. The AGM battery completed charging first and went in to maintenance mode. This allowed me to keep the charger on while the lithium batteries continued to charge. This is a great feature. Prevents batteries from being damaged by being overcharged. The only complaint I have is the length of the wiring from charger to battery. I had to add about 3 feet of wire to reach my trolling motor batteries. ... show more

    • On board charger
Great product, easy to install, I had the same charger before . I went with this one cause of price and product quality and if I change to lithium batteries I don’t have to change the charger. It also has a mode for battery repair.

    • Reconditioning battery seems to have worked!
Took out an older dual bank charger so now have a spare bank if ever needed. Much smaller and lighter than older units and while have not had the boat on the water (ice) it seems to have reinvigorated one of my trolling motor batteries. I thought it was a sales gimmick! Nice unit. I'd recommend and buy another if needed. ... show more

    • Customer Service and Warranty
Bought Gen 5x3 18 months ago. Worked perfectly! Suddenly developed a problem. Contacted customer service. They responded promptly and verified my problem. Requested me to ship it back. I did as they asked and expected at best a repair and some type of fee. 17 days later I received a brand new replacement! You can’t ask for better customer service or warranty. I’ll never buy any other brand. ... show more
