I'm new to the RC quadcopter hobby. Building a BetaFPV 75s micro which is basically plug and play. In attempting to charge the new battery, a 4.35v 50c/100c 1s LiHV 550 mAh on my ISDT SC-620 charger, I have the battery plug into charging board. The SC-620 read actual voltage at 3.92v. In the SC-620 set up screen I choose LiHv for battery type, cell voltage at:4.35v, cell count: 1s and current setting at .50a. When I start charge I get a warning that; Current Operation is not Supported. Confirm. I have gotten pass this point. You help is appreciated.
