Hey, I want to build mod my idea is a 3.7 mod with passthru, I've found a box with usb connection at the back here:
$7.08 2*18650 Battery Holder Case with Dual USB Ports (5V/1.5A Output) - charges iPhone/Android / emergency power pack / 1S2P at FastTech - Worldwide Free Shipping
so my idea is to pull out the batterie spring on the left side and then drill a hole put a 510 connection and next to it a button and solder a wire to the gold part near the circuit board so my question is: will it work? try to talk simple I don't really know electronics
