My rxgen3 dual is draining one of the batteries while off. Kills cell 2 overnite. Normal issue. Firmware fix?

I had this same problem a while back with an Ijoy Captain PD270 mod.
The batteries were only 2 weeks old so i thought it was the mod.
It happened every 2 days , one of the batteries was dead.
Turns out it was the battery itself. I swapped to another set and problem solved.
Maybe not your case but that's what happened to me.
