I have been running a 12v 750 size motor (around 16,000 rpm) with a 320 ESC and utilizing a 4.5a 12v gel battery.
Looking at utilizing two 7.2vx5000a nimh batteries - in series total of 12 cells. Easier to handle and a better fit. I think a little more run time as well.
It looks like this may not work due to the increased voltage. Should i stick with the gel battery and maybe upgrade to a larger capacity or should I be safe with the 320. Thanks.
