I'm starting to look for batteries for my F550 build. I found several 5000 mah batteries, with discharge rates of 20c, 25c, 30c, 40c, 45c, and 60c I also found a 5800 mah with a discharge rate of 30c and an 8000 mah battery that has a discharge rate of 30c My build uses E300 motors, DJI ESCs and a Pixhawk flight controller. NO additional weight right now, but will quickly add a GoPro and eventually an FPV system. MAYBE a 200 gram gimbal later Could someone please tell me which battery would be best, or better yet, explain how to figure what discharge rate is needed? Thank you very much!
