I would give them less than one star if that was possible. Their customer support absolutely sucks sucks sucks sucks! You will never speak to a person there may not even be a person there it may be AI you just get to send in a case and email back-and-forth. My knowledge of lithium batteries was that they lasted a long time sitting on the shelf. So that’s where mine sat for about a year because I only wanted it to back up power for my CPAP. Then after a year and a half, I put it on the trolling motor one day and it got super hot and I think it burned up the circuit board on the battery management system. The cell still read that they’re fully charged. But I can’t wake the battery up, and I can’t use it. They would do nothing to help me. They told me I had left it idle in storage too long. If this is the way this battery behaves it has to be dealt with. It’s a typical from everything else out there, and there should be giant red labels on the battery on all sides describing the techniques that must be used to satisfy their warranty procedures. Now I have a $500 Brick that could be useful but I don’t know how to make it work. I should’ve bought a Dakota. yes I could pay a little more but at least I could talk to somebody about it so if you’re looking for a lithium battery, go buy a Dakota or maybe one of the Bass Pro Shop brands but certainly do not buy from this company. They suck outrageously!
