12V 330Ah Small LiFePO4 Lithium Battery with APP, 200A BMS,10000+ Deep Cycle Lithium Iron Phosphate Battery Great for Winter Power Shortage, RV, Marine and Off Grid Applications

Great battery's, paid $333 each on prime day, i run 2 in parallel, running a 3000w inverter in a skoolie and it powers everything, the Bluetooth can be finicky (i use the Chinese battery app called BAT from the play store) but they seem to be close in in quality, only regret is not buying 2 more at the time, they have a 200amp bms but i usually charge them at around 100amps, takes around the expected 3 hours to charge each one at that rate (would be 1 1/2 hours at 200amps), when im running them in parallel it does take the expected 6 hours to charge 2 of them at 100amps, but again would take half that with the 200amps they max at charging. have been running them 2 months so far daily use, will see how they hold up compared to my chins battery's over time.

So far, it’s everything I had hoped for given the cost. The app is a bit clunky but the data I need is there (usage, voltage, historical while you are connected) it doesn’t give you much control over the battery itself and I have to force close the app every time to get it to connect to the battery again. But this was significantly cheaper than others and the power output has been phenomenal so far. We replaced 4 x 6v golf cart batteries and gained nearly 100 AHs. If it goes well for a few weeks I’ll probably buy another one to help boost our boondocking capacity.

I have had nothing but problems with this battery. It arrived 8/17/25. It is brand new and it appears the BMS system is not communicating with the app. I know the battery is full but is registers 0% on the app. It worked one full charge during the troubleshooting phase but is now back to not responding. Customer service is by email only and has not been helpful. “If it says 0% then it is empty” they told me. I had just charged it at 40amps so I know it was full. We leave tomorrow to dry camp and I have a flawed battery that is no good to me when I can’t monitor it’s use or charging condition on the app. 😡 They thought it was my charger. Wrong. I believe it is the BMS system and the manufacturer is not helping to remedy this problem with this BRAND NEW BATTERY.

I bought the Newtipower 24V 100Ah battery to upgrade my RV battery. I put it in parallel with my 120Ah battery. I first tested the Newtipower battery by itself, and I found it has 95Ah actual capacity, could easily charge or discharge at 50 amps. It's the real deal. It shuts down at 20.8 volts and comes alive as soon as you connect a charger. I got this particular battery, because of the shorter length, to fit in a small space. Even though it's smaller than other 200Ah batteries, it still weighs 44 lbs and is packed with power. It has a handy display to show state of charge, but I don't use it, as my battery is hidden away. Recommended.

Great price for a great battery. Have two others and so far so good.

Very impressed with these. I ditched genterators, and swapped to battery power to power my business, and I LOVE it, these batteries get the job done with plenty to spare. Customer service was great when I had a couple of questions, and responded fast as well.

I have been using for two years with no issues. I fish bass tournaments and run all my electronics on it. 2 graphs, lights and aerators. Usually fish 8 to 10 hours with no voltage loss. Highly recommend.

Biggest regret purchase here. One cell was undercharging and another was overcharging. Vdiff around 0.4V. No one to talk to - only chatting. Response was,"It's fine. Let us know, if it gets worse." It's not fine. Product power output is not as advertised. I continued to try and exercise it, but it was not improving. I sent another message, and the response was more of the same. I requested a return. Eventually approved with the help of Amazon. They refused to pay for shipping. I completed the process per their steps. Refunded eventually after a week.
