I hope I am putting this question in the correct thread/forum...

I have made several test flights with my new Electrifly PBY and have a couple questions about batteries.

I decided to go with two smaller batteries (they suggest one 3s1p 3200mAh 11.1v 20C. This is also with the recommended motor setup of two rimfire 28-30-950 motors. (Actually I think they recomend the 750, I just checked my motors and they are 950's).

With the initial recomendation of a single battery it makes sense to make a splitter cable to go to each esc. (I am using the 25a silver series esc). Under this setup (one 3200mAh 20C battery), is the 20C and the 3200mah being split between the two motors? I think I can answer this one as Yes. But, now go my my current configuration-

Two 1500mAh 20C 3S1P batterise and everything else the same. One more twist- I have connected each battery directly to one esc each. (Right battery to right esc, left battery to left esc). Do I still need 20C packs in this configration or would something like 10 of 15C work properly? I think I understand the mAh consideration as it relates to run time, but I do not understand when I might create a discharge problem for the battery and create a hazard by drawing more from the pack than it can handle?

Is there a problem running one pack to each esc/motor independently? I have made all my flights this way and do not see a downside except that I must plug in one esc at a time and leave some potential for uncontrolled motor running if I plug in the esc NOT connected to the rx first.

I think that is the end of my long question. My purpose here is to reduce the weight a bit by going to a smaller single pack or two smaller packs. My biggest questions is about the C rating. I am guessing that 20C was based on the fact that the original confiuration was a simgle battery feeding to motors, and since I am splitting the load I might be able to use "half the C rating and drop back to two 10C packs". If nothing else I might be able to save some money on the second set of batteries.

Thanks to all!
