how do i learn at how many amps to charge and discharge each pack/
is there a mathmatical equation.
Charge at 6 amps, with 12-18mv delta peak for the entire pack, thats .02-.03, use the lower setting for hotter ambient temperatures.
Discharge at 30 amps to 5.4 volts for the pack (6cell).
Generally I believe you can get away with a 2-3C charge rate. Meaning, you can charge at a rate that is 2-3 times the capacity of the cell. That is how the 2000's were at least.
So, you should be able to charge a 3300 at 6.6-9.9 amps. I frequently charge at rates up to 10 amps if I am late to make a race. I NEVER let the pack reach a peak at that amperage rate. You are safest at 5-6 amps charge, and I think your packs will probably last longer too.
