Hi guys. i have cellpro powerlab 8 v2. i am going to charge my x3 P3 batts at a time using Pl8 charger. i have heard Lead charging mode, but in this mode, i could not adjust voltage to 17.4V ( as original P3's charger). Adjusting Amps is only thing i can do. any suggest to charge many P3's batts at a time ( using powerlab 8) ?
