So again assuming your batteries are 2S, 8.4V is fully charged. You are using very little of your capacity. Hard to believe really but that is consistent with you saying you can run for an hour. 25C seems a bit low but your average current must also be very low based on how little you run your batteries down. You could go to a lower capacity but only if you wanted to lower the full-up weight. That would improve acceleration but might reduce traction. Nothing is simple and everything is trade-offs. Always look up the weight of a battery when considering choices. The higher C batteries do tend to be heavier.



The problem with DIY discharger is that they have no safety features like stopping at a certain voltage or doing any balancing. Just something for the OP to keep in mind. You definitely do not want to ever discharge a lipo below 3V/cell as that can really damage a battery.
