BC6 Input Voltage Reading vs. Sum of the Individual Cell Voltages.

[Lad]

Here is an interesting problem / observation.

When I connect my 2 cell Lipo to the BC6 for charging (and start the charge) the input voltage display immediately goes straight to 8.4V.

When I look at the individual cell voltages they are typical around 3.9v per / cell (as I would expect on a battery needing a charge).

So, why doesn’t the input voltage display on the main screens show the sum of the individual cells…?

As addition piece of information, the unit still seems to charge until the individual cells read 4.2V.

Thanks in anticipation………!

This is normal. The total voltage is reading the pack voltage through the main discharge leads.

The individual cells are being read by the balancer with the 300 mah load on them for balancing so the voltage will be different. As the pack becomes closer to fully charged the voltages will become closer. Even fully charged there could be a slight variance because of rounding. You could have the 2 cells showing 4.19V per cell fully charged, but the main display will show 8.4V. The 4.19 is really 4.194 or 4.196 for example.
