>Dear Peter, > >I you do hear about anything, please let me know. I am trying to use 4 NiMH >batteries in a pack and need a battery charger. Thanks. Brian. If you specifically used only NiMH batteries, then your life is much easier. Charge termination method: i. dT/dt - monitor the rate of change in temperature, normally you would terminate at 0.8C/min ii. -deltaV - monitor the drop in battery terminal voltage during charging. Normally -8mV/cell. 1 cell = 1.2V iii. Max V, Max T and timer cutoff thrown in for good measure. In your case of 4 battery packs, is it in series or parallel? Regards, Peter
