Ok, so I've got an idea for a build and before I start putting the work in, wanted to ask a question. Basically I want to build a twin engine pusher and have a specific battery setup in mind to give the stability/cg characteristics I want. The desired battery setup is as follows:
One 1500mah 3s LiPo feeding each motor independently (the C rating will be adequate for the motor). Now I want to put (for CG purposes and endurance) a single 5000mah 3s Lipo elsewhere in the airplane and use it to feed each of the two 1500mah packs in parallel.
I guess what I'm asking is can you parallel two 3s Lipos with different Amp ratings and/or with different C ratings? I guess you would need to make sure that the weakest amp draw battery cannot be less than the max demand of the motor. In other works, when paralleling LiPos, is the matching of the Voltage the only requirement? Can you parallel a single high capacity pack with two smaller capacity packs at the same time?
