vv box mod planning okr t/10

well planning my buck converter box mod came across a boost converter the ptn0405c and the idea i had was to use this board along with a 1 amp 5v mirco usb charger because that way i could boost the voltage cause my batteries would be in series and i could get the right voltage to my batteries think this might work plus i got 3 ptn0405c and a couple other free samples on the way so i think its worth a shot
