Tell us about yourself!
ahh. so you need the BMS board. Otherwise, it'll over charge and bad things may happen. As for the battery indicator, would you know what the max voltage it supports up to? I'm trying to use 12v amplifier for a project.
Nice job. I've always wanted to build a battery indicator. How do you know that the battery is fully charged after being plugged in the outlet? My concern is leaving it plugged in the wall too long and the batteries may "explode".
Question about the 3PDT switch. It doesn't have any polarity right? All you have to have is the same polarity for each side? Like the all the left pins are left channel, middle is ground and right is right channel?
