One simple phone call to VMAX ended up being one of the best customer experiences I have ever had. Caleb and the team were quick answer some of my technical questions regarding my choice for the second set of VMAX charge tanks and even quicker to ship them out. my first set of VMAX chare tanks were the agm extreme 12v 155AH, they were installed in my motor home as the house bank back in 2017. this bank has held a quality charge for the last 7 years of use. for charging and maintaining and inverting we utilize a 3000w pure sign wave inverter charger set for the proper charge/float voltage. we also use it to invert from 12v to 120v. also we run a 40amp mppt charge controller to harness 400w of solar to help the off grid charging. we have input 300kw via solar charging back into our first VMAX bank. simply for the age of the first bank we decided to replace with a new set. with the simple call to Caleb at VMAX his knowledge led me to the agm SLR12-155 tanks, that would suit are application with the same reliability. VMAX usa has been nothing but great to me and my family and will continue to use their products.

These batteries have been awesome! I use them as a 24V system driving a 160lb thrust trolling motor.

I upgraded the 8 batteries in my Polaris Ranger EV to 8 of these. They have performed so well, I bought 10 more to use as part of my solar/wind battery bank. I looked for some time, but have not found a better value
