Happy without builtin full bars and voltage on battery because bought before noticing no BT.
Thanks for the Great Deal!
Charging with Aims Power 12/24 75A
BMSs shut-them-down this morning.
No charging possible, so used my old 15A Schumacher SC1360 to bring them up to 60% and then a 20A lifepo4 charger. I kept the Schumacher connected until I saw Red-led on 20A charger. About then the Aims Power 75A got connected(bc the ac came on then).
