just run a ubec or the cc bec. much less weight then adding a second batt. less maintenance too.
I agree, the esc creates a lot of heat when modulating the lipo voltage down to 5-6 volts need for flight pack. The more lipo cells you run the harder it has to work. I have been using the ubec on all my EDF from smaller to 3000 watt setups . No problems. The new Castle bec looks very good too. Much lighter than a battery. Doug
