I bought this charger to charge some 18.5 volt 5 cell lithium ion battery packs I made. The price was great the shipping time was very good and the charger works great. The fact that it came with a 3 pin connector and also a female tamiya connector and alligator clips is also a plus. I give the product and the comany an A+ Thanks Lew
