Okay folks, I am getting to the last stages in my build and will post pictures soon. I am still waiting on a few small things to come in. But on that note I am about to order my batteries for my Jeti CB 200. I have a mix of JR 8911HVs MKS 777HVs and one MKS 1220HV for the nose wheel. Input Voltage on the Control box is: 3.5-15V. The MKS servos are rated for 7.4V to 8.4V and the JR looks to be rated at only 7.4V. I need help figuring out what is the best or recommended batteries to use. I will being using two on the CB. Please help I am trying to order them this week. I have read other post and I am just a little confused. I like the Life packs but they don't come in 7.4V or does that really matter with life packs? I have also looked at the Lipo packs. This is my first time with all HV and its been a while since I bought any batteries. Thanks everyone.
