Thanks a lot for that wiring diagramm !

Answers all my questions ;-)

Ok

So , i have 2 unprotected 3,6v 14500 900mah ultrafire and want to have an 7,2 v pack .

Does it only work with the 7,2v protection PCB or could i take only 2 protected 3,6v cells, build in...

When i have 2 unprotected 14500 3,6v ultrafire cells soldered in series do i have to use the PCB or can i charge them without the protection with the tenegy charger...
