LIPO receiver pack

[SteveK]

I currently have an unused TP2Sx2100 pack (blue stripe) and would like to add another TP2Sx2100 pack to make a 2S2P receiver pack for my Raptor.

The question I have is, would there be a problem using one blue stripe pack and one yellow stripe pack together or should they both be the same.

If the current per pack is below the max current of the least powerful pack, I don't see why you wouldn't be able to do it (if you haven't done it already).

You can even mix different capacity packs IN PARALLEL. The lager pack will give more current as it will drop less in voltage. As the packs are hooked up in parallel the voltage HAS to be the same. The packs will drain in the same ratio, not in the same current. Never, ever hook up different size packs in series!!!
