this charger is AWSOME! its less a charger and more an absoloute management system, 0.1-9.9 A charge, 0-30 cells, variable peak, 0.1-20A discharge and you can set the cutoff votage to whatever, motor run in, vis charge, cycles function, seperate radio charger (charge your radio and car at the same time), you can program the sx9, optional temp probe and computer linkage !!!
and no problems here EVER.
