View Full Version : Can you combine 2 Rx packs without problems?

I have 2 600mA packs that I want to wire up in parallel to a single
connector and use it as a 1200mA Rx pack. Will this cause problems?
Will the cells discharge into eachother, or something else weird?

Anyone try this?

No problem. Many larger batteries on the market are just smaller ones placed
in parallel. Placing them in parallel merely increases the effective surface
area of the individual cells thus reducing internal resistance thus
increasing their possible current output. On initial connection, cell
"discharge" may occur slightly but this is usual and of no consequence.

Let me know if I can be of further help or if the above explanation needs
elaborating.

I'm not an expert, but I suspect you should ensure both packs are in a
similar state of charge when you initially connect them. Otherwise you're in
danger of making a circuit through the weaker pack and reversing a current
through it, which could cause damage. (I think.)
