One caveat:

Do not mix batteries of different ages or capacities as one poster above has done.

Make sure that they are the SAME capacity and that you charge them both at the same time and for the same duration.

You want the batteries to be equally charged?

Why?

Well the "stronger" battery will discharge itself into it's weaker pair.

This is one reason we have balance chargers for Lipos... to keep all of the cells in a pack equally charged.

With two RX batteries connected to the same common connectors, things are no different.


One bad cell on one battery will adversely affect the lifespan and output of the other good battery as well.

That is why the "big boys" use special circuitry to switch from one battery pack to another when something happens to a pack. Effectively each pack is isolated from the other...

What you are describing does not do this.
