Intellect MC4 6600mAh 120C 7.6V Long Runtime Graphene Shorty Pack LiHV
Long runtime and consistent power for 1/10 offroad and touring cars
With the 2026 specification of the MC4 series, Intellect expands its competition range with a dedicated long runtime shorty. The BT2S6600MC4 shorty long runtime pack is designed for racers who need maximum runtime, a very stable voltage curve and reliable performance in a compact 2S format.
With a capacity of 6600mAh this LiHV shorty pack offers extended runtime for longer finals or demanding track layouts without adding unnecessary complexity to the chassis. The 120C discharge rating provides strong punch on throttle and keeps the voltage high throughout the whole run which makes the pack suitable for both stock and modified classes.
Thanks to state of the art silicon graphene cell technology the pack features very low internal resistance, reduced heat build up and a solid cycle life. As a LiHV pack it can be charged up to 4.35V per cell at a nominal voltage of 7.6 V which results in a noticeable performance boost at the start of the race and consistent power delivery to the finish line.
Main features
- Long runtime: 6600mAh capacity for extended runs in 1/10 competition cars.
- High Voltage (LiHV): Charge end voltage up to 4.35V per cell for increased RPM and torque.
- Silicon graphene technology: 2026 spec chemistry with reduced internal resistance and improved temperature behavior.
- 120C discharge rate: High current capability and strong punch on throttle.
- Shorty long runtime design: Increased energy content in a standard shorty footprint for more flexibility in racing classes.
- 5mm tubes: Robust high current 5mm gold plated tubes for low loss power transfer.
- Race legal: Approved for EFRA, BRCA, ROAR and IFMAR competition.

Charging and storage information
Never store the pack fully charged or fully discharged. For best service life we recommend a storage voltage of about 3.80V to 3.85V per cell. Avoid heat and direct sunlight during storage. A cool, dry place is ideal. A hot car trunk is not a suitable place to store LiPo packs.
For maximum life we recommend charging at 1C. Higher charge currents can noticeably reduce the life and performance of the cells and may worsen cell balance over time.
Safety note: Always use a suitable LiPo safety bag while charging, for example the RUDDOG HD LiPo Charging Bag (180x80x80mm).
Installation recommendations
Make sure the pack does not sit directly against hot components such as the motor to avoid unnecessary heat transfer. To keep motor and pack cool we recommend using an additional fan, for example:
If the connectors show heavy wear we recommend replacing the plugs on the speed controller in time to avoid unnecessary resistance. Matching replacement connectors can be found in the RUDDOG Distribution product range.
Warranty
All packs are covered by the statutory warranty period. Please note that improper use, wrong storage or mechanical damage can lead to loss of warranty claims.
