High capacity and low center of gravity for 1/10 offroad and touring cars

With the new 2026 specification of the MC4 series, Intellect once again raises the bar for shorty competition packs. The BL2S5000MC4 low center of gravity shorty was developed for racers who want maximum grip, a very stable voltage curve and a low center of gravity in a compact 2S format.

With a capacity of 5000mAh, this LiHV shorty pack offers extended runtime without adding unnecessary weight. The 120C discharge rating provides strong punch on throttle and keeps the voltage up throughout the whole run, even on high grip tracks and demanding layouts.

Thanks to state of the art silicon graphene cell technology, the pack features very low internal resistance, reduced heat build up and improved cycle life. As a LiHV pack it can be charged up to 4.35V per cell with a nominal voltage of 7.6 V, which results in a noticeable performance boost at the beginning of the race and consistent power delivery to the finish line.

Main features

• High capacity: 5000mAh for longer runtime 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: Updated 2026 spec chemistry with reduced internal resistance and improved temperature behavior.
• 120C discharge rate: Delivers very high current and instant throttle response.
• LCG shorty design: Reduced overall height and lower center of gravity for more stable handling.
• 5mm tubes: Robust high current 5mm gold plated tubes for low loss power transfer.
• Race legal: Approved for EFRA, BRCA, ROAR and IFMAR competition.

Technical data

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:

• RUDDOG 30mm Aluminium HV High Speed Cooling Fan
• RUDDOG 40mm Aluminium HV High Speed Cooling Fan

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.
