Charging - Two batteries and two switches
I just purchased some of the A123 2300 mah packs. On my 33% planes I have two of the battery packs, each to it's own switch, plugging into the reciever in different slots. Do I need to disconnect one of the batteries while charging the other? (I'm using a CellPro Multi4.) I read somewhere about a common ground causing a problem.
Thanks.
Thanks.

RE: Charging - Two batteries and two switches
That can get complicated. Using the Cell Pro 4 if you charge one using the balancing lead (you really have no choice) and both swithes in in a position(s) wher both batteries are connected power leads wise both will charge. One through the balancing leads and the other thrugh the power leads. You could use a Y-harness and charge both in paralle through the balancing leads at thre same time. To charge in parallel (either way ) they need to be close to the same voltage which they will be if they were both switched on during the flight.

He is using the CellPro Multi 4. You don't need to use the balancing port if balancing is not wanted. That gives the option of charge with balance or just charge.

RE: Charging - Two batteries and two switches
Interesting, I never realized this would be an issue. (I am charging through the balance plug.) I guess the easiest way is to unplug one of the batteries from one of the switches during charging to keep this from ocurring?
Thanks.
Thanks.
