Title: Battery bad or short?
Post by: trublupsu94 on March 19, 2023, 08:15:30 PM
Not sure if anyone is still using this much. I am new to US’s and just bought a unit that has the Obsidian v4 board and uses the 18650 battery. I charge the battery to full. on my VC2 charger is says full and is at 4.2v’s on the meter. If I leave in my saber overnight, it drops nearly 50% on the display to 3.8v’s. If I go two days, the saber doesn’t turn on at all. Is this a battery issue? A board issue? Or am I missing how to fully turn off the board? Any help would be appreciated.

Usually you gotta hold the button down for like 3 or 4 seconds but I'd get a couple spare batteries too though just because
