C/n (where n is a number) charging indicates the charging rate used. C represent's the pack's total capacity. Recommended normal charging is at a rate of 1/10th the pack's capacity. For example, a 600mAh pack would be charged at a 60mAh for 10 hours for a full charge (theoretically). However, chargers are not 100% efficient, so we leave it for an extra 3-6 hours.

Maximum charge rate of the pack is dependant on the type of cells in it. Some are designed to withstand faster charge rates, but typically it is not recommended to exceed C/1 charging unless you know your batteries are comprised of "Fast Charge" cells.

I am by no means an expert, merely someone who spent alot of time reading before purchasing a cycler myself. If you don't need fast charging, I would recommend the Einstein XL from FMA. It can do 2 packs at once, both NiCd & NiMH. https://www.fmadirect.com/site/Detai...1136&section=3
