Ratings and reviews

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.

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!!

Best Lifepo4 battery I have bought for my boats trolling motor. I have had 2 other brand TM lithium batteries die within 2 years because moisture intrusion. So far about 6 months since buying them I haven't had that issue because I believe they are sealed better with a rating of IP67. I would have gave them 5 stars but the Bluetooth app is giving me problems. It has a hard time connecting to the batteries. They MUST fix that bug.
