Since 4:30 AM last night, I have once again been experiencing an issue with my Venus 3 where the battery briefly jumps to 0 during both charging and discharging. Does anyone have any ideas? My Venus V2 is running completely normally. LOG: 10:39:18 @ffunes Do you think its a Firmware issue of V3 (148) ?
