Morning Blackwidow,
Batt needs to be over 70% charge at all times. Deff charge or replace with new and code appropriately. That is not issue popping fuse though. I had similar issue with bank 2 fuel pump Regulator shorted out popping same fuse once b4. On a separate issue, in trunk rt side fuse panel one day I decided to install a fuse in a open spot because why the hell not I thought. After I installed said fuse in trunk panel she kept blowing 15a under hood. I removed fuse in trunk that I randomly installed and all issues have since cleared over 2yr now…
Hope it helps steer u in proper direction, GoodLuck
