Ok folks... I give...I've got a problem.
I have a KK2.1 control board a 120a power distribution board. 4-30A ESC and 4-28 motors with a 5000ma battery that is brand new and charged.
Here is the sequence of what happened.
I had a kk2.1 board that worked fine with a 2200ma battery. But I let the battery discharge too far and it wouldn't recharge. So I ordered the a new 5000ma battery. When I put the new batter in the kk2 board would light up at all. So I thought I did something to the kk2 board. I bought a new kk2 board and put it in and it too wouldn't light up. I originally had a smaller (30 amp) distribution board and thought I might have blowen that up. So I got the new 120 amp pdb. Put that in and the kk2 still wouldn't light up. So I borrowed another (new) kk2 board from a friend to try and it too wouldn't light up. I thought I might have reversed the power leads on the kk2 boards so I was extra sure that I didn't do that on my friends board.
I use the Turnigy Accucell charger and it says the battery is fully charged and working properly.
I really have run out of ideas. I've tried everything I can think of like just 1 esc connected with one motor. Nothing seems to allow the kk2 board to light up.
I hope I have described the problems sufficiently that someone can say "hey I ran into the same problem"
I have no idea what to try next.. Any ideas out there?
