Looking at ordering some EnerG 7 cell stick pack style configuration, what does matched and unmatched mean, and how important is it?

Thanks again!

Cheers, thanks. Do you think they are worthwhile? It sounds as if purely in terms of longevity the concept makes a lot of sense..

i've got a 8 cell ener-g form pro match, and i must say its awesome. get a matched pack, they will have better performance becuase the cells ar ethe higest capactiy/discharge rates ones they've got.

ive got an energ 7 cell unmatched and it works great but if i did it over again id go with matched.

Not all cells are created equal. Some preform better than others. The best performing ones are picked out of the bunch and paired with other cells that perform in a similar manner. These are "matched" cells because they all fall close in range of run time, internal resistance, and average voltage. Unmatched cells are the left overs from the matching process that couldn't be paired closely with the other higher performing cells. But they're still good.

Matched cell packs require a good deal of maintenance to keep them performing at their peak. Over time the cells will get out of balance, meaning that some will start to charge/discharge faster than others, or will have slightly different voltage at full capacity. When that happens its no better than an unmatched pack as far as performance goes. To keep matched packs at their best you want a balance tray and a 30 amp discharger to condition the cells. If you don't have and use that equipment, the extra cost of matched cells is really a waste because in a month of use they'll likely be no better than unmatched.
