(The laser also ignore this awful picture)



Making it work with only 2 batteries
1. Buy Aluminum foil then put it on It's back after the 2nd battery (Until It's the same width as the battery or full)
2. Close it with the cover.
3. Magic (Though It's kinda weak, It's OP).

Adding 0.5x power
Just add little aluminum foil after the 3rd battery.
