First Battery Set Up

I finished putting together, at least in a temporary setup, last night. I plugged in the charger this morning to give the batteries their first charge and after about an hour, the Volt Blochers have started shunting, just like they are supposed to. Take a look:


  1. So the shunts act as some sort of controlled current path between the batteries? Meaning that they are connected in series?

  2. The Volt Blocher is installed across the terminals of the battery. When it is charging, current will flow into the battery until the battery voltage reaches ~3.6V. Then the current starts to be shunted to the 10W ceramic resistor, allowing the batteries that have less charge to continue to charge. Granted that I haven't stressed the pack at all but during testing, it only took me 3 cycles until all the batteries in the pack are reaching the 3.6V cut off at about the same time, indicating that they are all balanced.

    Sorry it took so long to respond to the comment.

  3. No worries. Thanks for the info.

    Glad to see you are back at it.
