But I really hope one day they add the ability to actually see each cell’s voltage. Right now you just have to trust the app when it says they are “well-balanced” but I’d rather know for sure. Also my 12v 125ah will only charge to 99% no matter how long it’s on the charger. I don’t know if it normal cause it’s the first battery I ever bought for my kayak. ### 4/5 — Bien correct. *2026-04-08, version 1.2.1* Ça fait la job ### 2/5 — Beaucoup de bug *2025-12-16, version 1.2.1* Beaucoup de latence, à quand une version Apple CarPlay ?? ### 2/5 — App works OK with 12.8V/100Ah-4p1s *2025-08-30* Update: After running close to 20 discharge/charge cycles on my 12.8V100Ah group 24 smart batteries, I’m downgrading my review from 5 stars to 2 stars. Some features in this app are helpful; others are buggy. For example, in the App Store the picture shows 2 of 3 batteries live as the yellow toggles indicate. I can only link 1 battery at a time to observe realtime status. Why can’t more than 1 battery be linked at a time? I have other Bluetooth devices that can run simultaneously. I’m running 4 batteries in parallel (4p1s) and when my system showed to be about 50% SOC, I had 3 batteries that appeared to be at 30-32% yet 1 remained at 100%. That can’t be right. I don’t know if it’s the BMS or the app, but hopefully future updates will fix the problems. That said, I’m still glad I bought the smart batteries for the few extra bucks. Some info is better than none. OP: I can’t speak for others who have experienced problems, but v1.1.8 of this app works just fine on my iPhone 15 running iOS 18.1 and BMS firmware 1.4.0. Setting up a bank of Low temp/Bluetooth 12.8V/100Ah batteries was simple and straightforward. I was impressed enough with the original 2p1s setup that I ordered 2 more of the same batteries for additional storage. Creating a 4p1s system was as simple as deleting the previous configuration and adding a new one to reflect the change. All batteries can be shifted around in the configuration diagram according to their relative position within the bank. Each battery can be viewed individually or the entire system can be monitored as a whole. IMHO, the Bluetooth option is worth the extra few $. **Developer response:** Thank you for your feedback! We will continue to strive to provide quality products and services. We wish you a pleasant day! ### 3/5 — iPad landscape mode and dark mode please! *2025-07-10* Please implement iPad landscape mode! My iPad stays in a mount in landscape with power almost all the time. Removing or turning it just to use the app is a pain. Please fix! Also when using in a dark room all that white screen is so bright! Please also implement dark mode! Thank you! ### 2/5 — Verbesserungsfähig *2025-07-03, version 1.1.9* Grundsätzlich ist die App gut, das BMS der einzelnen Akkus kann jederzeit via Bluetooth verbunden werden und liefert zuverlässige Echtzeit-Daten. Sobald aber ein Batteriesystem erstellt wurde, verliert die App dieses System immer mal wieder. Das nervt tatsächlich, da ich im Wohnmobil gerne jederzeit die Gesamtkapazität (2 140Ah Akkus parallel)sehen möchte. Irgendwann, nach 1-2 Tagen erscheint das erstellte Batteriesystem dann plötzlich wieder. Support wurde bereits informiert, passiert ist nichts. Von einer XiaoXiang App ist diese leider weit entfernt. Ein wenig mehr Entwicklung würde ich mir wünschen. ### 4/5 — Bien *2025-06-09, version 1.1.8* Fait le job sans décorum mais bien pratique au quotidien. ### 1/5 — Signs out repeatedly *2025-06-08* Could be easier if the app wouldn’t repeatedly sign you out every 5 minutes. ### 1/5 — This app is useless. *2025-06-03* “Bluetooth device not found” Hmmm……..i paid for one. ### 1/5 — Garbage *2025-05-24, version 1.1.8* The mere fact that I need to register the app at a web site is like "what the … heck". Also it requires like a second factor in the UI which worked at the 3rd try . The app itself is sometimes working and sometimes it just doesn’t want to connect to the BMS. I can’t really recommend the app and as a consequence the battery . ### 3/5 — App works OK with 12.8V/100Ah-4p1s *2025-05-20* Update: After running close to 20 discharge/charge cycles on my 12.8V100Ah group 24 smart batteries, I’m downgrading my review from 5 stars to 3 stars.

I created my account and can log in online. But the app is impenetrable. ### 2/5 — Power Queen *2025-04-18* The batteries and app are GREAT!!! ### 1/5 — Battery Level *2025-03-09* The App says my battery has 1% but I’m still able to use my trolling motor for for hole day. I don’t think it’s accurate when it comes to reading the percentage at all. **Developer response:** We apologize for any inconvenience caused. Please provide more details about the problem you are experiencing to our customer service department by e-mail service@ipowerqueen.com so that we can analyze it and help you resolve it. ## Most critical reviews (10 lowest-rated) ### 1/5 — Indication % *2025-11-10, version 1.1.9* Les indications en % sont parfois pas juste par ex en connection 220v la batterie perd 1% régulièrement et dès que le 220 est retire ça revient à 100%! Bug application ### 1/5 — Doesn’t see the device/battery. *2025-10-27* Doesn’t see the device/battery. Bluetooth doesn’t see the device no matter how I approach it…. ### 1/5 — Overlander *2025-10-22* Haven’t been able to get the app to work. Will not send me a code, and, yes, I have checked spam. ### 1/5 — Can’t connect Bluetooth *2025-10-14* There is no QR code. I have charged the battery with a brand new LiFePo4 charger. No email response. I guess my next step is return ### 1/5 — Does not show cell voltages *2025-09-03* App is better looking than most but why does it not have a way to see cell voltages?? ### 1/5 — Email verification is a poor idea *2025-07-24, version 1.1.9* Having a an email verification to login to see the status of your battery is an incredibly lousy idea. If you are out of cell service range, you cannot check your battery. They’ve already received this notice and have done nothing about it. I hope they consider getting rid of that email verification ### 1/5 — Utter rubbish *2025-07-16, version 1.1.9* The App that allows me to connect to a battery locally via Bluetooth requires me to not only Register and Sign in but doesn’t even properly implement Sign in with Apple and still requires a separate E-Mail address to send a verification code to. It also requires me to agree to a 3rd party “User Agreement and privacy Policy”. This is absolutely unreasonable. I should be able to use the App without any Registration at all. As a result of this kind of limitation I’m not using the batteries Bluetooth feature. ### 1/5 — Can’t Connect *2025-06-23* Does not connect to the battery even though Bluetooth is enabled. ### 1/5 — Junk *2025-06-10* Junk ### 1/5 — Plus de connexion avec le logiciel *2025-06-08, version 1.1.8* Plus possible de me connecter avec l’application, il y a une petite tête qui fait la tête et c’est marqué We’re sorry !!!!! ## Most praised reviews (10 highest-rated) ### 5/5 — Bonne application *2025-12-15, version 1.2.1* Transmet les informations nécessaires au bon suivi de la batterie. Les indications semblent fiables. Service client très réactif et très efficace. ### 5/5 — Все працює чудово ! *2025-11-20, version 1.2.0* Доволі проста в користуванні програма. Шкода тільки мені, що немає Української мови. ### 5/5 — This is good stuff! *2025-10-08* I love this app. I have the 125ah smart edition batteries. The app is intuitive and provide quality feedback. Thanks Power Queen! ### 5/5 — Perfect for my needs! *2025-07-20, version 1.1.9* My Group 27-12.8v 125Ah LiPOFe4 battery has been in use in our 33’ Grand Design Fifth Wheel RV for 60 days now and it’s perfect for on-the-road operation of our new Frigidaire 14 cu/ft residential refrigerator, giving me 14+ hrs of travel time between campgrounds. ### 5/5 — Working great *2025-05-17, version 1.1.8* Love the bluetooth , great deal ! ### 5/5 — Spitze *2025-05-03, version 1.1.8* alles völlig tadellos ### 5/5 — Great budget battery *2025-03-04, version 1.1.8* This so far is a great budget battery, holds charge and the app is easy to navigate. If I could suggest one addition to the app or would be an alarm for low charge, bypassing the need for a battery monitor! ### 5/5 — App works well with 12.8V/100Ah-4p1s *2025-03-01* I can’t speak for others who have experienced problems, but v1.1.8 of this app works just fine on my iPhone 15 running iOS 18.1 and BMS firmware 1.4.0. Setting up a bank of Low temp/Bluetooth 12.8V/100Ah batteries was simple and straightforward. I was impressed enough with the original 2p1s setup that I ordered 2 more of the same batteries for additional storage.

We wish you a pleasant day! ### 5/5 — Simple setup *2025-02-16* I can’t speak for others, but v1.1.8 of this app seems to work just fine for setting up my 2 Group 24 Low temp/Bluetooth 12.8V-100Ah Trolling batteries in a 2p1s configuration. In fact I’m so impressed with these batteries that I ordered 2 more of the same to upgrade to 4p1s for my off-grid FEMA trailer. Even though 200Ah would likely be adequate for my current needs, pun intended, I’m trying to get ahead of Trump’s tariffs as I suspect prices will increase soon enough. **Developer response:** Thank you for your feedback! We will continue to strive to provide quality products and services. We wish you a pleasant day! ### 5/5 — Extra *2024-12-11, version 1.1.6* Bonne application,intuitive et en français.
