The question is related to quadcopters and else. So my quadcopter (brushless dc motors and electronic speed controllers powere by 3cell lithium battery 2700mah 25C) has thin wires on the main power port, Im trying to figure out if it could affect current flow, I know that when gauge is too small it can overheat, burn or melt, but can it just restrict current flow without fires?
I having hard time to figure it out because once I tried to jump start a truck with cables that were too thin and the starter motor just weren't crancking the engine, wires weren't getting hot or anything... connecting another pair of wires in parallel resulted in successful start of the engine, and it was matter of seconds, not like the battery had time to recharge.
Can some one please explain this to me.
