After completing the dynamic balancing on both fans using an old iPhone 3G with Vibration and following a very handy guide on RCGroups I’ve done a test run using the new packs (65C 2250mah – 146.2 amps continuous) with both motors running a mix of full throttle and half throttle:
Before dynamic balancing (on 2200 45C pack):
Running around 65amps / 650watts.
Peaking 70amps / 670 watts.
After balancing (on 2250 65C pack):
Running around 61amps / 630-640watt.
Peaking 63amps / 650watts.
