Re: sBitx #sBitx PA MOD Plan #sBitx
I would add a bunch more pictures. ?I think that is the plan but here are some suggestions: * Use a pointer or screw driver to identify various resistors and capacitors. * Create very close pictures

Re: Another battery question
Don, That Lumenier is a 10 Amp-hour battery, nominally 14.8 Volts. Rated for 25C, which means a maximum current of (10 Amp-hour) * 25C = 250 Amps, where the 25C has the rather odd units of Amps per

Re: Another battery question
Very cool, Jerry!? It sounds lime you've a good handle on things there!? I agree that commercial and most DIY BMS have wimpy shunts. I expect you already know that you likely don't need to shunt
