I've used one of these batteries for my trolling motor for a few years and it has worked flawlessly. I have a larger motor now and bought two more batteries. I'm having an issue getting the app to work with the new batteries. The App says 0% power, the cells read full, the charger says full. I'm not sure what's going on. I imagine the app needs an update.
Bought 4 100 AH batteries to replace the lead acid batteries my mower came with. Have used for over a year with excellent results. Did have to buy a charger made for LifePo4 batteries. Also hooked up a 48 volt dc to 120 volt ac inverter to the same batteries and ran a window ac with no problem.
Seems flawless. BMS works well and protects battery from overcharge, low temp, etc. Whenever I have had questions, I get an email back from a human that takes the time to explain. Wish the self-heating version had been available when I bought. Next time I will pick up two of those. Really good product and exceptional pricing.
