Ok, so this thing is nasty! Comes with small and large connector adapters, tells you pretty much anything you could possibly need to know about what's going on with the battery during the charge. It charges my 9.6v 2000mah batteries roughly 10 min/battery. Discharge takes a little bit longer, but not by much. I have only had one issue with the fuse vibrating causing an intermittent open so the battery would stop charging, a thin piece of duct tape over the fuse to hold it in place took care of that issue right away. If you want to spend this kind of money on a battery charger/discharger, this is the one you want.
Fast charge/discharge time
Fuzzy Logic Option!!
Small and Large type connectors
Multiple data readouts
Price??? Well worth it though
Fuse vibration issue rather quickly(thin strip of duct tape over fuse solved)
