Compact power and consistent performance 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 BL2S4600MC4 has been developed for demanding racers who want maximum performance and a stable voltage curve in an ultra light, compact form factor.

With a capacity of 4600mAh, this LiHV shorty pack offers the ideal balance between runtime, weight and power delivery. The 120C discharge rating ensures instant punch out of the corners, while the voltage remains high and consistent over the whole run. This makes the pack an excellent choice for high grip 2WD and 4WD applications.

Thanks to state of the art silicon graphene cell technology, the pack features a very low internal resistance, reduced heat build up and improved cycle life. As a LiHV (High Voltage) pack it can be charged up to 4.35V per cell, which results in a clearly noticeable performance boost at the start of a race and strong power delivery throughout the run.

Main features

• High capacity: 4600mAh for an optimal compromise between weight and runtime.
• 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.
• LP shorty design: Low profile case for flexible weight distribution and chassis balance.
• 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).
