These are better than the others in similar price range due to build quality. Main gripe is the app refused to work on my obsolete android 7 phone. This is because they were demanding GPS location information and even though I turned it on - it still wouldn't work. However, I found a workaround. Install a free app called Fake GPS. It spoofs your location and allows the app to run. This would get five stars if they had a better app. Support tried to help me but could not. I ended up figuring that Fake GPS thing out myself. The battery is good enough that I just ordered a second one before a scoundrel dictator decides to force more tariffs and causes the price to jump higher.

First off, the batteries themselves are fantastic so far. Have had two in use for over three months and just picked up two more. Not an issue to speak of other than the following.The reasoning for three stars is the app or apps not working at all. The main, original app to connect to and monitor the batteries was BMS Meta. I am using the Android based app and it no longer functions since the latest update. It is unable to get past the new permissions setup process, which by the way appears to need access to virtually everything you do on your phone. The BMS Meta app was functioning in an acceptable manner in the previous versions. It was very simplistic and basically a status display screen for your batteries, which for my use case was just fine. Better than not working at all.Watt Cycle themselves appear to have started or progressed development on their own in-house battery management app and it is available as "WattCycle by ShenZhen Wattcycle Power Co., Ltd" It actually works pretty well with finding any batteries within Bluetooth range and having far more settings available to configure and adjust. I am unable to comment as to whether all the settings function properly when being used due to not being able to properly test. The one big issue is the individual batteries are very random whether they will connect with the app or not. This Watt Cycle branded app seems to still be in development, so I am hopeful it will improve drastically in the coming months. At least becoming a bit more stable and consistent would be a plus. When either one of the apps functions properly, the overall battery and app combination gets five stars all day. Without a functioning app, you are left with a dumb battery and no way to monitor power levels and other stats unless you buy an additional shunt or battery monitor. So please be aware you may not always be able to access power level info readily at this point.Thanks for reading and best wishes with your power storage journey.Update: WattCycle reached out unsolicited and offered an acceptable solution to the matter. Fast and unexpected resolution was very much appreciated. Good on WattCycle for taking care of their customers. Five stars for the physical batteries and product support.

We've all been seeing the reviews on YouTube. Well, they are correct, the battery is everything it's cracked up to be. I have purchased 3 Minis so far. I had a question about one and got a response back in less than 24 hours.This battery is a great product at an unbelievable price. The Bluetooth model is well worth the money.Thanks for the great customer service.

I have been waiting for years to pull the trigger and switch from AGM to LifePo4. I finally did it after reading reviews about WattCycle, particularly from YouTube Will Prowse who highly commended this battery's quality and build. The added benefit of the cost pushed me to try this battery. My battery arrived and it was not working and only had about 3 volts when I tested it with my multimeter. I was concerned that I just ordered a brick and this will end up costing me much more in the end. I contacted WattCycle customer support and they responded right away. After a couple emails and pictures of my problem they told me they will send out a new battery to replace the one I originally bought at no cost to me. The new battery arrived and everything worked as it should have. This company not only builds a quality product, but stands behind it also. I'm very impressed with their customer service and desire to take care of their customers. These batteries do what they say and have all the features you want and need from Bluetooth capabilities and even low temperature cut off which many budget batteries don't have or don't work. I highly recommend WattCycle batteries, you won't be disappointed.

I bought this battery for my 2022 Cougar 22RBS camper. I have wanted to switch over to a LiFePO4 battery, and this one seems to fit the bill. Works great, compact size, complete with BMS bluetooth app for monitoring the state of charge of the battery. The app lets you know the current in and out of the battery and any warnings. The BMS does have an automatic balancing function when the battery is fully charged. This will keep the battery cells balanced and ensure maximum capacity with the battery over time. I would buy this battery again in the future.
