Hi,

of course I know that the Ulta Duo Plus II is a Schulze charger. But the Ultra Duo was there before the 330d. And the little Schulze ia a little bit more complex. It can charge from 1-30 cells, the Graupner only 4-30 cells.
Just for interest, the new Ultra Duo Plus 30 is not a Schulze as usual.
@Juan:
For what kind of use do you want it? Big flightpacks or the absolutely control over all your batteries? Á very important point is the charging performance measured in W(att). The higher it is the higher is the current with higher numbers of cells.


MfG,
