Simple electric load controlled by MOSFETs. I am currently building this to discharge Li-Ion 18650. A microcontroller will measure the voltage of the cell(s) and stop the discharging once a desired voltage is reached. This will prevent over-discharging. Also will there be a current sensor to ensure that the current never surpasses save usage of the cells. This shall also be controlled via the microcontroller, which will off course controll all the MOSFETs.
The reason for the weird resistor values is, that I got a bucket full of 0.1Ohm/25W resistors I wanna give purpose to. If I wanted to spend money on this project, I‘d off course have used properly weighed resistors.
