I can’t believe this is what sun gold power puts out to their customers to monitor their expensive 24 V batteries. Does not work properly with iPhone? Really it’s 2026 more than half of the people Apple products. I wish I’d never bought this system. They were shady from the get-go. Now they don’t answer when I ask for support for the app. ### 5/5 — Works for me *2025-07-19* App works the way it should. Would like to see an update for a better visual app ### 1/5 — Don’t download *2024-07-27* Using 1.1.22 app version and for whatever reason this app being on your phone makes it to where you can’t connect to servers for internet on your phone. Not a good app, removed it from phone and everything’s works fine like normal. App definitely has a lot of issues and bugs. It is unfortunate that this is the only way to monitor the BMS on the sungold batteries. Knowing this was the out come would have bought different batteries. ### 1/5 — Best I can do is.. It works.. Kinda *2023-08-12* It's pretty rough around the edges. Wish there was a way to secure access so not just anyone could mess with the battery. ### 1/5 — What the heck *2023-06-16* Apparently having your software on your phone updated is not a good thing because the app does not work if you have the latest software on your devices! ### 1/5 — Completely Broken! *2023-05-21* So I bought three LiFePo4 batteries for over $2,000. One of the selling points compared to other batteries was the “built-in Bluetooth BMS,” so I tried connecting. Stuck on “Bluetooth connecting - please later” for over an hour; the cancel button on-screen doesn’t work either. First of all, what kind of grammar is that? Second of all, it doesn’t work - whatsoever. Will return the products for the same reason. ### 1/5 — Doesn’t Work Whatsoever *2023-05-21* Bought a few new lithium batteries with the built-in Bluetooth BMS. Tried to connect as soon as we received the batteries and stuck on “Bluetooth pairing.. please later..” Garbage - don’t buy batteries for this capability. ## Frequently asked questions about LL BMS MONITOR ### What is LL BMS MONITOR?
