The Graupner is a good charger but the Schlutze charger is better. Although Schulze makes the Graupner, the Graupner has outdated software. The Schulze ISL 330 will charge all of the battery types that you specified including BOTH types of lithium ion. The Schulze is the same price as the Graupner. Additionally, you can spend an additional $40 and upgrade the Schulze charger with an RS 232 interface with software to chart and graph your batteries on your PC!!! The software will enable you to see if the specs on your particular pack have changed. I don't know of any other charger that will enable you to do that. Oh, this charger can accomodate up to 30 cells!!! Chris Huhn also has one and maybe he can add to anything that I may have left out. Kevin

P.S.----The text on the Schulze is in english.
