Default Receiver Battery Pack Questions

I have a Venom 1200mah (older, needs to have a wire fixed) and Duratrax 1600mah (just bought today) hump pack nimh. I have a Duratrax Piranha digital peak charger and am wondering how I should be charging them. I've been out of the hobby for a while.

I have been charging the Venom 1200mah @ 1 amp, 8mV/C

Is this correct? I don't really know what the 8mV/C means or how it effects the charge. I'd like to have a normal charge when I have time and a quick charge when I'm bashing.

Thanks

What about the peak rate? Duratrax recommends 8mV/C for NiMh batteries.

+1 on 1 amp and 5mv. At 8mv you would overcharge the pack. I charge my packs at .9 amp charge and discharge cycle and 1.2 charge only at the track to top them off.

The detection V is exactly that.When those batts peak they have a large fast change in voltage. The mV you set is how much change the charger looks for to determine the pack is peaked. The higher the # the more the charger will charge before it shuts off.When packs are new they are more reliable/precice in that characteritic & the charger will be able to propperly peak them a t a lower mV setting. The older & more dissimiler the cells get the harder it is for the charger to sence their true paek & you have to raise the mV# up to get the pack to not false peak. If you have to go above .8mV per cell toss the pack & get a new one. If one cell of the 5 is really bad it wont have the same V change as the others & its a per cell # your setting on the dial only the charger actualy looks at it as a combined V & like I said that 1 cell not responding propperly will cause the charger to over charge the others looking for that Voltage change & that will cause 1 or more cells to vent & if your in a hurry for your next race you may notice untill you put your car down on the track & pull trigger.So after all that just know lower# is better if your batt is good.
