The simple project is built around an ATmega8 that utilizes PWM and ADC to control the charging current of NiMH battery cells.
The project is a single PCB where 3 LiPo battery chargers are combined with an output voltage of 4.2V for each charger.
The project was designed to produce a balancer for LiPo cells in order to prevent an excessive difference between stored charges.
A simple battery powered power amplifier with adjustable gain control which is built around LM386 low voltage audio power amplifier IC.
The project is intended for typical rechargeable batteries used by R/C devices, various consumer product batteries, and electronics hobbyists.
The device utilizes a large 50W resistor to be used for discharging NiCad battery pack.
