Pictutes are below my other post provided by another member ( Two cellphone
mod ) and overcharge protection is built in my usb cable because I did not have enough room in my mod, plus it will protect my other mods so I dont have to protect every mod. Its fairly simple protection
device useing silicon diodes, but it depends on starting voltage. You can buy silicon diodes at Rat Shack but I got mine from a old transformer. When I can post pictures I will show my remote over charge protection
device.
