Mini 24V 100Ah Lithium Battery, Up To 15000+ Cycles, 24V 100Ah LiFePO4 Battery, Built-in 100A Low Temperature Protection BMS, Great for RV/Camper, Trolling Motors, Solar Off-Grid, Marine/Boat

This purchase was as a replacement for another "dum" brand that was supposed to be "fine" ;-) but showed up DOA. It arrived 6 days after I ordered it. It was packed well and arrived in excellent condition. Just like the other battery, this one weighs 57 pounds which is pretty amazing for the capacity. I already had an enclosure ready for the prior battery containing a battery switch, circuit breaker and shunt. A quick connection to the 8mm terminals and I was in business. I did ask my own wiring and had a 120 Amp Anderson connector ready to connect to the same that came on my 60 amp charger. One big difference between this and the other battery was it has Bluetooth capability. They supplied a card with a QR code to download an app but the webpage it sent me to was in Chinese. I figured out how to download the app but it was useless. It was also in Chinese with no obvious way to change the language. Research indicated it was an awful app anyhow. In the research, I discovered people were using the Xiaoxiang app successfully put out by the manufacturer of the BMS used in the battery and it works fine. I compared its information with the information on the Victron shunt app and there were small variations but I would believe the accuracy of the Victron app. The battery came approximately half charged. I successfully completed the charge at a sustained 60 Amps. I saw one of the four cells was a bit aggressive in the charging being ahead of other three causing a voltage limit before the others. The next day I ran a capacity test at a sustained 30 amps and the battery did a fine job with equal cell voltages down to the end. I was able to get 308 Ah out of it and I've subsequently got 310 Ah. I ran another 60 Amp charge. Once again, the cell voltages remained equal to the end and then that same cell took off again causing a cell voltage limit before the other three. Time will tell what the performance will be like. The battery came with a manual but it's really just a listing of LiFePO4 battery parameters for batteries of various capacities and not really anything specific to this battery. Being a generic alphabet soup-namedChinese battery, it has no warranty, suspect expectations of battery cycle life and no warranty. Time will tell what the performance will be like. Hopefully it will hold up well over time. A YouTube teardown video shows pretty decent construction and it was shown that another random-Chinese-company-name battery that's showing up recently on the market is just putting their label over this label already on the battery. That video also showed well placed temperature sensors and properly functioning high and low temperature cutoff.

This battery is the right chemistry (safer LiFePo), the amp/hour rating and price very competitive. I was careful in choosing this battery and I am happy to say I picked the right one among the many choices. The delivery was prompt and the packing very very good. We're using this in our R.V. and it is working out just right, our plans include days where we'll need the power and our solar charging keeps it up during the day so we can operate freely in the evening and night. It easily handles our power needs for 3 people on trips to the desert (where we NEED to run our air conditioner a lot!) We are happy with this purchase, in fact, I am about to order another one for my ham shack (amateur radio) at home so that if the big earthquake hits us in California, we can continue to operate our equipment as part of emergency services and it will run our refrigerator and lighting easily for days, even if our solar panels get little sun.

This battery was much better than I expected for the price. This battery has a 300Ah capacity with built in monitoring showing current charge level current charge rate and discharge rate. The battery also has built in BMS for charge monitoring and automatically shuts off charging when temperature drop. I highly recommend anyone looking for a battery for off grid or rv purchasing this battery.

I love this Pup Battery so much I just order 2 more!!! It's been perfect for my off grid A-frame. Couldn't be more pleased. I recently jumped into Solar and started off with 2 deep cycle 29DC Everstarts from walmart and would have to power the down system nightly (Ampinvt 80a and Jupiter 2000) just to keep the batteries from dropping below 50% which the maximum safe discharge for Lead Acid. Once I upgrade to 1 PUP lifepo4 (309ah) We were able to run that one battery all night and still have around 35% left the next morning. I also am in the process of upgrading our Solar system to a Victron system. These 300ah Rock!!!!! Im buying More

So I bought a 300AH for a 12V trolling motor.I have to say I over bought ;) after full 8 hour day and using a trolling motor for a long time the most I can use was 18% ie 82% left. One day ai tried to just use as much as I could , to test, and had 78% left.One annoying thing is that for 300ah I could not find a battery box at all, either double and then its way big or nothing.Ended up rolling my own Plano orange tackle box picked up at bass pro shop.Definitely get Bluetooth version to be able to check current , %left, and to even shut battery off with it.

I haven't had it long enough to comment on the longevity of the battery. I like the form factor of the 12v 300AH battery, but the bluetooth connection is garbage. It drops on the phone app and drops when connected to Home Assistant. No way I can rely on the sensor data for any kind of automation. The connection is just too unstable. I have another budget battery right next to this one and that bluetooth connection is rock solid. Unless things change in the near future I can see myself returning this item.UPDATE 08/20/25Seller reached out to me after I posted this review. I went around in circles with them trying to explain the issue. They asked for the bluetooth mac so they can do remote diagnostics on it. I finally gave up and went to do a return with Amazon only to find out that "This item isn't eligible for return". It looks like I'm stuck with it.One other thing I noticed was when it was shipped to me originally the box had no caution sticker for battery contents. Every other battery I've had shipped to me has always been clearly labeled on the outside of the box with a UN3481 label.
