I’m a programmer with a few spare arduino nano. I haven’t worked on circuits in a few years, and this seems like a good exercise.
Since LTO cells have specs that I like, I want to experiment with lto cells and bms design for my next ebike battery.
Could sampling cell voltages be as simple as using a pair of analog mux, a capacitor, and a few relays to disconnect the capacitor from the cell when connected to the board?
Is it worthwhile to find a more precise circuit for use with new cells?
