I'm using a lipo to power the wireless router and ethernet board on my robot. I'd like to use a hard cutoff to save the lipo from over discharge. Most of what I see is for RC applications and are soft cutoff and work in conjunction with the ESC to lower or pulse the output. Not a good idea for the electronics. Is there a way to modify it for a hard cutoff or is there an equivalent circuit that's not too involved? I could probably use an arduino for this but that's overkill.
Thanks,
Dave
