Battery Charging Question

Battery Charging Question
I am running venom 1200 NiMh 5 cell 6v receiver packs in my cars and have been using my traxxas quick charger that came with my REVO to charge them. After getting a new pack I saw where Venom doesn't recommend that charger to charge the batteries. recently the packs have not held a charge well and went extremely low after only one 5 min heat race. I now have a Duratrax peak charger but unsure what setting I should use as the packs only say to charge @ 1 or 2 amps but 1 is best for long battery life. My question is and I have not been able to find the answer in archives: What does the mv/c value mean? That is a value that has to be set when charging and I'm unsure what to set it at. It has a range of 1 to 20mv/c.
Any help would be appreciated so that I peak charge my batteries but not damage them.
Thanks

With mv/c (Millivolt per cell) with a NIMH you can probally use 5mv/per cell This is the point at which the charger will say the battery is fully charge. A nicad uses 10mv/c. If you use a setting lower than 5mv/c then you are under charging your battery anything over 5mv you are slightly over charging.
hope this helps
Pass you soon...

Small receiver packs on that charger I set to 6mV/C and a current up to 2A, no dead battery yet....
Regarding your 7.2V (racing?) packs, for NiCad you can go up to 2x its own capacity, with NiMh I would not go further than 1.5x its capacity.
With the 6mV/C it works fine for me with all kind of NiCad and NiMh batteries.
