I bought three lithium 100ah batteries to power my bass boat trolling motor. When they arrived one of them was bloated and physically unlike the other two, just under the plastic case . Once notified the manufacturer replaced the battery immediately and asked me to dispose the questionable battery. I'm wondering if Will would like to dissect this battery?

I'm designing my 12Kw 48v system. It needs to do 4500w into 240v split phase both off-grid and grid tie. Have looked at all of Will's reviews and am undecided on what inverter-controller would be a good choice. Needs to be UL for grid tie. Interested in the Growatt line, but unclear which units are hybrid and can work on and off grid. Am also considering IQ8+ microinverters from Enphase.
