hi, mr team wave,
i bought a Lightning2 discharger today at my local race meeting instead of the Novak smart tray SE, when i got home i plugged it in and put a set of 4 cells on it to start discharging, but i got a very high pitch squeal as soon as all 4 cells where in place, please advise what the problem is, when i disconnect one of the cells it stops!!!
cheers
steve
