Low Cost BMS

This is an open source BMS for your home-made electric vehicle. It includes files to help you build and program your own circuit boards. You will need to get the circuit boards made, buy the components and solder them to the boards, then program the chips on the boards.

There is one master board and multiple module boards.
The master has a screen to let you know what is going on. It also has a LED as a warning light in case a fault occurs (low cell voltage for example).
You need to make one module for each cell in the battery pack.
