M mrquacott New Member Sep 11, 2003 #1 Have you some ideas for a charging circut suitable for this pack: pack voltage 6V (no. 5 Ni-MH 1,2V - 7000mAh - "D" cell GP model 700DHC) The charge rate should be be: standard 700 mA (0.1C) x 14 hr (DV= 0-5mV/cell - Timer cutoff 105% n.i.) Fast Charge 3500mA (0.5C) x about 2.1 hr (Temp. cutoff=40-50 C degr - dT/dt=0,8 C degr/min) Thanks a lot MrQuacott
