The batteries were packed very nice! I purchased 4 and have only had them a few months and so far they seem to be of very good quality, i am very happy with these batteries in my 41'4 Gulfstream coach rather then the lead acid constant monitoring. The AGM style is the perfect choice for me as I am not spending millions on lithium batteries and I have never had a problem with my 20 yr old coach. Time will tell of course but I feel I have done my homework and made a very good choice.

Purchased two of these 6v AGM heavy duty batteries, wired in series to produce 12 vDC. The power from these batteries connected to an Recreational Vehicle(RV) Charger Inverter to provide power to the Living Quarters(LQ) in the absence of a 30 amp 120 vAC landline. These were to replace my previous AGM 6 vDC batteries of the same Brand that lasted 7 years before their output voltage was too low. Great battery, each one does weigh over 70 lbs.

These very heavy batteries work perfectly wired in series to provide a very deep, strong 12 volt for my living quarters of my Itasca Spirit motorhome. They have good depth and work better than others I have had.

Early delivery was spot on. Delivered at 90% charge so easy to fully charge. Worked right away. Check a lot of prices and these were the best. Kind of heavy at 78 lbs each.

The packaging was robust. Being AGM (better than gel or wet cell), there was no damage or spillage. In fact, you can actually use them on their sides if you need to. I used to remove and bring the batteries from my motorhome inside my house for the winter, which is getting much harder not I am in my 60's. I spent more than I ever have on these batteries but have been able to leave them outside in below freezing weather with only a monthly check. They hold a charge pretty well during non-use in below freezing weather. I would buy them again.

Put them on a charger / maintainer and it didn’t take long to reach “ float “….As someone else said they are Heavy… Going in our Arctic Fox Truck Camper with Solar on the roof … I will update this review IF any issues develop but the batteries appear well made….

Vmaxtanks, charge tanks quality exceeds mil spec requirements. With the thickness of the plates and the technology, these two strings just added to my personal solar generator system will outlast any other AGM technology on the market today. FYI, A solar flare or an EMP will take out a lithium BMS. There’s nothing you can do about it, don’t waste your money on lithium.

I didn’t know what to expect ordering almost 600 lbs of batteries. Also changing brands from my usual. But I went out on a limb and I’m glad I did. It arrived in three days, coordinated delivery, and came on a pallet. I tested all 6 batteries and each of them were good. Topped them all off and swapped out my 10 year old AGMs (all but one of those tested good). Everything worked well on the rig. Now if they last as long as my precious batteries I’ll be very happy. Batteries are made in Vietnam but they came perfectly packaged with covers screws and all the extras. Very happy assuming they hold up as promised.

Batteries showed up in a timely manner. Have them installed in my 5th wheel. Will see how they hold up.

I built a home Solar generator system with an Aims 24 V low frequency inverter. My original 2-24 V strings are Harris Battery’s.. I expanded my system with eight more 6 volt Vmaxtanks batteries to complete 2 strings of 24 V batteries with the XTR 235 amp hour mil spec battery. These batteries will last in a home back up, solar system for 15 years. I’m very confident in that. FYI, the lithium battery has a battery management system called a BMS. This BMS is susceptible to a solar flare and an EMP. The Vmax tanks batteries could be hit by 10 EMP’S and not be damaged Wera lithium battery will be toast with one hit That’s why I chose AGM batteries. As far as I’m concerned, the Vmax tanks, batteries is the best batteries made for this application.

So far so good. I have only had them for a bit over a week. The old batteries were lead acid rated at 225 ah. I hated having to check fluid levels all the time. When new I was able to keep everything running in the coach about 6 to 8 hours with an all electric refrigerator and carrying on normal activities. Quiet time at 9:00pm dry camping and the batteries go low by 3:00 to 4:00am and the fridge stops working. Made dry camping impossible. After installing and fully charging the VMAX tanks I was able to go for 12 hours and only dropped to 50% charge. We are dry camping again.

I prefer these batteries for my ham shack. Plenty of amps and better than the trojan batteries I was using. Looking forward to getting more for my home solar setup... Highly recommend these batteries.

These AGM batteries are the best I have found for RV's. I use the 6V batteries and get better runtimes and performance. I highly recommend them. I have been selling and installing them for many years. I run them in my own 5th wheel.
