UN4RACING, I'm glad to hear you like our packs.......as for who makes them........well we do...in house....It's by far the best solution.....you order your pack, the order goes to production..........they make your pack with matched cells only and the connector and tap of your choice. It's win win and super fresh packs are out to you in little as 24 hours.

As for charts there are some posted over at RC Groups in the Batteries and Chargers section. But I'm not sure if they list the new copper tab cells.

The rest is all factory secrets that I don't know nor do I want to.
