I'm for someone to build a battery management system based on the TI BQ77PL900 IC. The batteries are 20 lithium (LiFePO4) batteries connected in series. Additionally, you will have to make a microcontroller front end, that will display pack properties on an LCD, the microcontroller will also store data periodically on a SD card. Once a prototype is built, I'll need a PCB designed so they can be mass produced.
Thank you for looking.
A few more details:
The BMS is for an electric scooter.
the microcontroller should also have an input from a 5V hall pass sensor, so it can display speed.
