I have batteries of several voltages, and I want a way to discharge them to 40% (3.8V per cell) when I'm not using them (other than draining them in the devices they power). Is there a circuit I can use to discharge them to that voltage automatically? Right now, I'm using a voltage booster/regulator to charge them up to 3.8V per cell, but I also want to be able to also discharge them to that voltage. I don't mind buying/making one for each battery voltage. It'd be nice if there was a circuit like the regulator that I can buy that can serve this function.
If someone has a circuit idea, I'd love to hear about that as well. I just need something to open the circuit when a preset voltage has been reached.
