Good to know. I thought they had to be "like" packs as far as voltage and mAh, but I guess that makes sense. Unfortunately I will have to keep them paired up in 2's as they have different balance plugs. The 5000's are Turnigy with XH plugs, and the 2200's are Hyperion's.

I'm looking at the parallel cables HERE & HERE as I don't see any of the "Paraboards" with the TRX plugs I use. Will they work just as well?

Thanks,
Ryan
