Motorola GP2000 HT battery

I have unloaded this HT battery and I modified the battery and the charging system using a 5volt dc micro usb module that can be stepped up in voltages and other supporting modules.
Material: BMS module 2S 3ampere
MT3608 micro usb step up module
18650 battery
Adequate cable
