Long runtime and constant performance for 1/10 off-road and touring cars

With the 2026 specification of the MC4 series, Intellect is expanding its competition programme with a dedicated Long Runtime Shorty battery. The BT2S6600MC4 Shorty Long Runtime was developed for drivers who require maximum runtime, a very stable voltage level and reliable performance in a compact 2S format.

With a capacity of 6600mAh, this LiHV Shorty battery offers extended runtime for longer final runs or demanding track layouts without unnecessarily complicating the chassis. The 120C discharge rate provides high current reserves and ensures a powerful punch when accelerating out, while the voltage remains at a high level throughout the entire run. This makes the battery suitable for both stock and modified classes.

Thanks to modern silicone graphene cell technology, the battery has a very low internal resistance, reduced heat development and solid cycle stability. As a LiHV battery, it can be charged up to 4.35 V per cell at a nominal voltage of 7.6 V. This results in a noticeable increase in performance at the start of the race and a constant power output right up to the finish line.
