It works, but it's ugly and clunky. Give it a dark mode instead of the sickly pale blue. After Bluetooth connects, while getting battery data, don't display 0% charge and 32°F temperature, wait till you have the actual data. The bizarre animation that takes half of the home page, looks like a Star Trek transporter. It should be replaced with something simple and understandable or just eliminated. Then use the space to expand temperature and voltage readings instead of hiding them.

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.
