Got a new battery and the Grin Satiator says 'shorted' sometimes when I plug it in to charge. It's one of those batteries with a BMS that requires a bump to get started, so when I 'force start' the charge, it charges normally and works normally otherwise. Anyone have any experience with this? The battery is an HL brand, 15Ah, 48V nominal. I've had 2 older batteries from them that also required a bump, but they never caused the satiator to say 'shorted' when plugged in.
