Buy these...

Wow. If you're looking for no nonsense, never fuss, safe, heavy duty solar batteries, stop looking. You found them right here. I have two separate battery banks getting their energy from separate panels. Both systems are the same except for the batteries. One system has 14 marine deep cycle batteries from Wally World and the other these VMAX. No need to check the levels and adding distilled water or checking specific gravity. These guys are sealed. I charged them to 100% before wiring them together in parallel. I'm running a 10,000 watt pure sine wave inverter on each system to keep my refrigeration refrigerated and anything else I need to or want to run off of these two systems. Just ordered another 8 to replace those 14 marine dc batteries. There is absolutely no comparison. Set these guys up and you can rest easy for the next 10-12 years. If you're into solar or getting into it, buy these. It's a chunk of money but well worth it. You are getting what you are paying for.

So far, so good on an off-grid workshop and dojo..

I bought 8 of these batteries for my off-grid workshop and dojo. I am running a 2700 Watt solar farm to feed them, managed by a Magnum Power charge controller and inverter. My system has been in operation nearly a year. So far, so good. I run a mini fridge 24/7 and in the winter I ran one ceiling fan to circulate the heat from a ventless LP heater. All lighting is LED. For cooling in the summer I have screened windows and ceiling fans with open, screened doors-hey, this system just wont support A/C. But it runs all my 120vAC shop tools with no problems. Most woodworking is waiting for glue to set or for the finish to dry so I don't press these batteries too hard. I never discharge them below about 70%. When I am training in the dojo, at my age, I don't run the lights and fans more than about 3 hours. I am planning on many years of service before replacement.

Lots of power for camping

I can absolutely recommend this product for RVs. This ran our entire motorhome for two days, reasonable use, including 1500 watt inverter, and barely touched it. Did not even have to connect the solar panel, never ran the generator.

Used for solar

With a capacity of 155ah the battery is a good choice for my solar system.

One simple phone call to VMAX...

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.

Dependable value for the money

I have been using these batteries for 9 years. I wanted to retire the first 4 I bought and expand my system. Those first 4 still work but discharge a bit faster than they use to. Not bad for 9 years in constant service. Now I have 16 of these in my system and during a grid down situation, I live like a Prince!
