    Canada, of course!

    Many 7.4V Li-Po batteries have 3 wires. 0V, 3.7V and 7.4V. Then a balancing charger can charge the first cell from the 0V wire to the 3.7V wire and completely separately charge the second cell from the 3.7V wire to the 7.4V wire.

    Hi, know this is a very old thread but better keep it here than start a new one for the same question.

    I would like this circuit to cut voltage for a 4s battery pack. Cut at 13.6v (3.4v*4=13.6v)
    Dont know what I need to replace thoose components.

    Seems to be hard to find products like this. Would be great with a circuit with variable voltage but if someone helps me with above I'm more than happy.

    Any help is highly appreciated!
