The product quality is excellent. Compared with other similar energy storage batteries, it is affordable. Moreover, its energy storage effect is a pleasant surprise to me. I bought two, and the stored electricity is sufficient for my family to use normally during peak electricity consumption periods and power outages. Appliances like refrigerators, TVs, and air conditioners can all operate simultaneously, and the battery can supply power stably without any power outages or voltage instability. Also, its safety makes me very at ease. It has perfect overcharge, over - discharge, and over - temperature protection, so I don't have to worry about safety issues with the battery.
If you have troubles with home energy storage and other aspects, I highly recommend you to buy Dyness.

Cheaper than an AGM lead acid, comparable price to an LiFePO4, and half the price of many other vendors. Good deal!

Working as intended so far with no issues. Running 4 in P on a 3600w inverter.custoker support and after sales support has been fantastic and oddly dare I say the best ive ever seen so kudos to dyness for that and I expect in the event of a failure they will be easy and on hand which is a nice after sale point. Installation was easy and straight forward with charging first then installing in your setup. For the price if building a 24v system these are worth a hard look in my opinion. I cant speak for longevity but if anything happens ill update this review so as is right now, great batteries for many applications from a 24v rv/camping setup to a backup inverter or even a whole house inverter system. Go 48v and you get up to 20kwh without issue or worry, almost cant got wrong!

It is smaller than the lead-acid battery of the same capacity, saving storage space in the RV. It is said to have a lifespan of 10 years, which is much more durable than the 3-5 years of lead-acid batteries. It can save money in the long run. It also charges quickly with the matching charger.

The battery life is much longer than the lead-acid battery I used before, and it is easy to install. It does not get hot when charging, and there is no pungent odor. The manual says that it has overcharge and over-discharge protection, and it is very reliable to use.

Great batteries! The BMS from Dyness is far superior to other systems I’ve used. I can easily check the battery status anytime from my phone, and the Bluetooth range is excellent. This is already my second order from this company — highly reliable and worth every penny.

After years of relying on standard lead-acid batteries for my 12V trolling motor, I decided it was time for an upgrade. I had looked at the big-name lithium brands, but their prices didn’t feel worth it. Then I discovered Dyness, and after comparing specs and value, the choice was easy.

I purchased the 12V 100Ah Group 24, and it arrived just two days after ordering. The first thing I noticed was how incredibly lightweight it was compared to lead-acid/AGM batteries. On its first run, I powered my trolling motor for 6 hours in steady wind and current on the river—using only 7% of the battery’s capacity.

I’m beyond impressed and would recommend Dyness to anyone looking for a reliable marine or multipurpose lithium battery. I’ll definitely be buying more in the future.

Awesome batteries—well-packaged for shipping and impressively lightweight. Truly the best value for the money, performing on par with big-name brands that cost three times more.

One of my favorite things about the Dyness Mini 12V 100Ah battery is its sleek design—kudos to the team behind it.

Was so happy to get an equivalent battery for my sump pump. Old 7 year old AGM 120AH lead acid battery that weighs 80 lbs, would have cost $600 dollars for an exact replacement, is out. This battery weighs nothing and if I wanted to, i can use it with an inverter on the go or as backup power. I hope it lasts just as long or as longer. The Paperwork it came with is detailed with a storage baggie.

These batteries arrived on time and came pre-charged which was a nice touch. I ran into some issues early on wasn’t sure if it was the solar gear (turns out it was) or the batteries themselves. Their support team was super helpful and easy to deal with though. They walked me through fixes for the solar equipment and I didn’t have to hassle with the batteries at all. Highly recommend Dyness definitely buying from them again.

Great batteries. I tested the 100ah one and it actually came in slightly over 100ah, which is a nice touch. Also really appreciate that they arrived already charged—no waiting around to start using them. Right now I’ve got two set up in parallel, and they’re doing a solid job powering my whole living room. I’m charging them with a Victron 100/50 and 700w of solar, and it’s been smooth.

Their customer support is awesome too—they’ll help you work through any questions you have. Not a big deal, but I even love the graphics on the battery. Overall a great experience, and I’ll definitely be buying more.

I bought four batteries two months ago. They look great and are supper light weight. Low temp charging disconnect with a great low price. I think I'll recommend my friends to buy them.

The quality is great, and the shipping is fast.my wife took the delivery for me, and when I opened it up, I found everything I needed included. I’d say this brand is the best bang for your buck. The instructions are especially well written and easy to follow. Highly recommend!
