ESC help
 

New to the scene, new to the site. I tried a search before posting and didnt come up with anything. If I missed it sorry. Please point me in the right direction. So I am deployed to Afghanistan and bought a RC18B off ebay. Came with everything I need but instructions and a charger. It also came with 6 batteries. I plugged them in to see if any had juice and maybe make sure the thing worked. All but one one had no power. I noticed though that when plugged in the ESC would beep and/or give me a red light. The one that had a little power left I think beeped but the light was green. Is there an instruction guide on ESCs and how they work and what to do and what it is trying to tell me?? The ESC is a Hobbywing Brushless Ezrun 18A and the batteries I got are all different. They are all 6 cell. 2 are Tenergy 1400 mah, 1 is AE RC18T Sport Pack 1100 mah, 1 is Reedy 1600 series and the last is Hi energy 1600 mah. I dont recall which one gave me the green light and worked for a min. It was either the AE or the Hi energy. Anyhow, thanks for lookin hope someone can offer their wisdom. Im off to browse some more of the site. Thanks again!!
