Qty 4 VMAX V6-225: 6.2kWh 24V AGM Solar Battery Bank for Home, RV, or Industrial (4) 6V 225Ah AGM Deep Cycle Batteries 6 Volt Maintenance Free

Working great

Was good while it lasted, but total junk in the end. I had to write this review to inform everybody to NOT buy these. I installed 4 of them in a brand new high end system in March 2019 (small off grid cabin. A few 12v lights and an inverter to run a small water pump). Exactly 6 years later (March 2025) they’re dead. They show a full charge but will go to nothing when a load is applied. Obviously, 6 year lifespan is a ripped off. Save your money and buy good batteries designed for solar systems.

Purchased a 4 pack of these batteries for my RV solar project back in December of 2017. We’ve gone camping many times in the last almost 6 years and these batteries have not disappointed.However, I say this and wrote a review now to give real world experience with 5 years and 7 months of extreme usage on these batteries and they JUST NOW are showing signs of a diminishing charge being held.With that said, I will be replacing them after the summer with a brand new set because they are no longer taking a full charge and seem to drain down a lot quicker. So just shy of 6 years isn’t bad in my opinion.

Just installed these, but seem to be fine. Others have ordered these and been very happy. Went from the flooded batts to the AGM and I am sure I will not regret that decision. Just make sure you have everything disconnected when hooking up these or any battery. Great shipping as well. Arrived faster than expected and well boxed. Be prepared, they are heavy!

Perfect size replacement and it was an upgrade on the amp hours compared to the old batteries! Being that they are sealed and maintenance Free makes it so nice just to be able to plug in and let charge overnight!

I have 16 of them and are 4 years old on a 48 volt system and will not hold a charge. Yes we use a lot of power but we have 2800 watts of solar panels and a 8.5 KW generator for backup that runs now at least once a day. Last year it didn’t hardly run at all. I have to get new batteries

Well since I have had these batteries for less than a month I cannot comment on durability. We are on our first little camping trip since I put these batteries in my Class A. I have 4 6 volt batteries combined in parallel and series to give me 12 volts at 450 A Hrs. They have worked good so far. They provide electricity for my wife’s CPAP machine, along with a extra Norcold ref/fre we have in a basement compartment and I. An brew my coffee the next morning so life is good. I would expect no less from these batteries, they are costly. But if I never have to do maintenance on them it will be well worth the money.

Something is not right with these batteries. They charge three times as fast as they should and drain three times as fast as they should.I have had a solar set up for many years and this isn’t right.
