12V 320Ah Built in 200A Bluetooth BMS LiFePO4 Battery

One of my main concerns was running Starlink off-grid, and this battery handles it without any problem. I’m getting roughly 20+ hours of Starlink runtime if that’s the main load.

In real use (Starlink + fridge + charging devices), I usually get around 1.5 to 2 days before recharging.

I’m using a 2000W inverter and everything runs smoothly. No unexpected shutdowns so far.

Installed this in my travel trailer and paired it with a 40A DC-DC charger from my truck alternator. Charging has been stable and no overheating issues so far.

I’m running a fridge, lights, water pump, and occasionally Starlink. On a normal day, I can go about 2–3 days without needing to recharge, depending on usage.

Big improvement over lead-acid — especially not having to worry about voltage drop. Just make sure you’re using a proper lithium-compatible charger.

Installed this in my RV and it’s been working great so far. Running my fridge, lights, and Starlink without any issues. Huge upgrade from my old lead-acid batteries.

Running this with a 3000W inverter in my van build. I mainly use it for a fridge, laptop charging, lights, and occasionally small appliances.

The battery handles continuous load well. I haven’t pushed it to the absolute limit, but under normal usage it stays stable and doesn’t heat up much.

Definitely recommend pairing it with a good inverter and proper wiring.

Installed this in my van build and took it on a 3-day off-grid trip. Powered everything I needed including charging gear and running fans overnight. Very reliable so far.

So far so good, I have installed them in my van, took a full charge, and are working as intended. Seems like a solid deal thus far. Time will tell, but currently I am happy with this purchase!

I bought this to replace my lead acid battery in my Jayco RV. It was a pretty easy swap out due to the fact that my converter has a auto detect for battery type charging. The solar charge controller had to be set to lithium and other than that it was a easy switch! I love the fact that it has an app so that you can monitor performance and functions. So far, so good! Capacity is high, price was good and delivery was fast!

Been using this in my small off-grid setup for about two months now. No issues so far and the Bluetooth monitoring is actually really helpful.

Awesome way to expand my backup power setup. I was using a 100ah battery to expand my power station setup for the last year. After a day and a half long power outage depleted my system in about 10-11 hours I decided to expand it. I found this massive 320ah lifepo4 for a great price and tested it last week. I got over 4100 watt hours out of the first test and worked it into the expansion box. It’s almost the size of a group 31 battery, maybe 1/2” or so taller, but made the box work. I like having the app to monitor because it’s easier and cheaper than adding a shunt and screen than having to calibrate it all and whatnot. It’s crazy to think it’s basically the size of the old battery but is 3x the capacity. Super happy with the purchase and glad to be prepared for the next long term outage.

This battery (320ah) fits perfectly in my 2019 Navion view (sprinter chassis). Had to remove the rub rail and the inline fuse to make it fit.

excelente

Working great once you fully charge them.

The two batteries in parallel have been working perfectly since replacing the three old 100ah’s. One week ago. Very happy with there performance. Brian

These batteries are awesome! Although difficult to find and set up initally, the software program has the information needed and am finding after 3 days in service, the cells in both of two batteries (in series for a 24V system) are within 2 millivolts of each other, so they balance extremely well. Replaced 4 - Vmaxtanks 155AH Solar Batteries (great batteries too, but...) with two of these 320AH ones and work so much better it is amazing.

I have a 2025 Flagstaff travel trailer and it came from the dealer with a lead acid battery and I was able to just take the old battery out and put this new one in and so far it works great and I really appreciate having the app so I can see what's going on with the battery. It's too new to really tell how long it will last but the installation and the delivery was perfect.

Replaced two lead-acid batteries with this and the difference is huge. Much lighter and I get way more usable power. Charging is faster too.

Éstas son unas baterías súper eficiente, la pueden comprar sin ningún tipo de problema

Did a lot of research before buying and this one stood out for the price. Performance has been better than expected and capacity seems accurate.

Excelente

Excelente calidad y precio

So far battery works great love the app

ok

Great product for the price, this is my 3rd battery. It is as good as what the RV dealer sold me for two times the cost!!!

Used one season so far, much better than the two 6vt batteries I had. Removing the two cleared some room and dropped some weight from my rig. App interface is great. I use the trailer factory charging system, gets it to 80%, then I plug is an aftermarket one made for these batteries to finish it to 100%. Usually charges from morning till I leave in the late afternoon and everything is 100%.

I had some issues initially with keeping it charged, but that was more based on my use and the lack of sun. The battery itself is working beautifully now and as a human, I've become slightly more functional as well. I'll likely add another at some point, but it's a great battery.

This battery and a 3000w sine wave inverter will power your van or camper fully. Add solar and go for days!

I have two 12 volt 320 AH batteries and will buy 2 more. I run my two chest freezers, refrigerator, and all other off grid items with no issue. I have them in a steady temperature, and I also did the math on their capacity and what I am using prior to purchase. They are great batteries so far and have been performing for 8 months solid. I have never brought them below 50 percent by design.

Great Battery for my RV replaces flooded deep cycle batteries in my Motorhome. They make it usable for boondocking but be aware you need to replace your RV voltage converter to one that is compatible with LiFePO4 batteries but well worth the price. If you only use 1 get the 200A BMS if you want to use it to start your Generator. Make sure it will fit in your battery box I had to modify mine but it was not to difficult to do.

These batteries are awesome for my bass boat trolling motor. Easy charging and longer lasting than lead acid batteries.

So far I am very impressed with this little battery. The size is smaller and lighter than the car battery that came in my used rv. It is hooked into my solar supported system, time will tell how it holds up. BTW, it arrived 13.1 volts, fully charged which made me happy

I bought these batteries for my travel trailer for the time I just want a fan, lights and my TV. When no other power source is available. So far, they are working as they are suppose to.
