This is a NEW Hobbico Accu+Cycle Plus complete battery cycler. It will Charge, Discharge, and check the condition of any battery. The instructions have been misplaced but really not needed in order to use it as all services needed are listed right on the Cycler. This is a VERY nice tool for R/C System Batteries. If you don't have one, this is your chance to get one at a VERY REASONABLE price. I am asking $33.00 Plus the actual shipping costs to be determined at closing. If you have any questions please email me. Thanks for viewing my AD.
