To John or Fizzyo or anyone in the know I have a question about connecting batteries in Series. I connected (2) 7.4 2s 2200 mah fully charged batteries in series using an EC3 series harness to achieve 14.8 volts. I was able to get 514 wp on the volt meter with 34.04 ap and 14.64 vm which seems like enough power for the aprox. 7-8# Super Cub but wanted to get a little more watts to be closer to 100 watts per lb. I then tried a 11.1 V 2200 mah battery and (1) 7.4v 2200 mah battery. I was only able to pull 386wp, 28.11 ap 13.57 vm. There was also a noticible decrease in power. I know that I should be able to connect different volt batteries as long as the mah is the same according to instructions that I had from Tower Hobbies on the Matt Chapman that I had previously built. I am not sure what is wrong. The 11.1v 3s battery is older and a different brand name. any suggestions. I have a 5s battery on order but wanted to try this in the meantime. Thanks Terry
