    16" Folding Bike Sliding Friction Drive

    Using a mosfet as a switch?

    The topic of a proper power switch comes up again and again and the options so far are quite limited (high amp car hifi breaker, connector loop, 60€ aps switch which is very out of stock). Now I asked a friend about it and he told me we could basically use a mosfet for switching. As far as I...

    Main Switch in + or -? On board charging.

    I am going to wire a 9 pin plug to my next board for onboard charging and balancing. Does it matter if I break the + or - with my ec5 loop to disconnect the esc? Does it matter on which one my antispark is? From what I read so far, not really. But better safe than sorry :)

When I charge, I set the charging to stop at 5Ah input, but when it reaches the capacity stop, it never reaches 4.2v per...
