TrakPower Century packs are named for their 100C discharge rate, which offer competitors a huge edge in response time and acceleration. All are approved for ROAR-sanctioned 1:8- and 1:10-scale racing events, and balanced for longer life and maximum voltage.
Century packs offer a distinct weight advantage, as well. Since battery weight is directly linked to capacity, the capacities of Century packs have been carefully trimmed to provide winning results with less weight. What’s more, the new high-density materials used to manufacture Century packs help control heat, and the result are light packs that reduce swelling even in high amp/heat situations.
Hard-case Century packs are available with high-efficiency bullet plugs or with a factory-installed Star Plug and JST XH balancing connector. In addition to 11 Century packs, TrakPower has also added five 50C packs to its line-up.
