@RussellLite I agree with @wr420 .. my board came out of the box the same as you describe.. you need to turn the board off and on a few times, then plug in charger while the board is turned on.. charge for 48 hours to balance all cells as the app only reads one cell which could be charging first, but all other cells are flat.. this info was given my FM support and sorted the board.. I do an overnight charge once a week to keep it running good and batteries balanced..
