Ratings and reviews

I've had to reset the 'charge gauge' on two batteries after manually balancing cells that the internal BMS didn't seem to be able to balance. 11/30/25 Got two new replacement batteries for ones that have been locking up. Much better cell balance. 12/18/24 Update. Dropped a star because... Would you guys PLEASE SAVE THE BATTERY NAMING INFO so when an upgrade happens, I don't have to go through AND RE-NAME EVERYTHING!!

Really clunky app. Overly difficult to use with multiple batteries. Bluetooth is underpowered and while everything else in the power compartment reads just fine from outside, I have to get the phone _in_ the power closet to even get a reading. About 50% of the time one or more batteries just don't show up on the app for not apparent reason. Other brands of batteries I use don't seem to have these problems.

motor home. 628ah lifepo4 battery. Hard to get strong Bluetooth connection but battery is in a steel case in metal basement. Need*** accurate explanation of what when and why I would use the charge and discharge buttons in app. App needs better realtime updates to screen. sometimes do not trust screen updates are complete. I kill app and reconnect to recheck. perhaps rotate font colors each refresh.
