Grateful

I purchased 2 of these batteries and was looking forward to their arrival. As I was waiting on them a friend asked me if my onboard charger would support lithium batteries. I hadn't given that a thought. Sure enough, it would not. Unfortunately, I had to return them. The company was tremendous to work with and I am very grateful and satisfied with their customer service.

Great light weight battery

This battery is a great replacement for the original deep cycle battery that came in my camper. We were recently on a month long road trip and boon docked several times. We always had plenty of power to spare. The only problem I had was that nobody makes a battery box for this large of battery so I had to custom fabricate one. I truly love how light weight this battery is. I have recommended this battery to several of my camping friends.
