SMC Racing HCL-RS 7.6V-6400mAh 120C LiHV 5mm Inboard Shorty Hardcase

The SMC Racing HCL-RS 7.6V 6400mAh 120C LiHV Shorty Hardcase is part of SMC's High Cycle Life Race Series — a line of race packs developed with an independent factory using proprietary cell recipes, not generic off-the-shelf cells with different labels. The HCL-RS formulation is optimized specifically for the demands of RC racing: better voltage hold, less sag under load, and lower internal resistance compared to generic high-C packs. The 7.6V LiHV chemistry provides a higher nominal and peak voltage than standard 7.4V LiPo, delivering more punch and speed on the track.

Key Features

• HCL-RS (High Cycle Life Race Series) — proprietary cell recipe optimized for racing
• 7.6V LiHV chemistry — higher voltage than standard 7.4V LiPo for more speed and punch
• 6400mAh capacity — true mAh ±5%
• 120C continuous discharge rating for high-demand racing applications
• Low internal resistance — better voltage hold and less sag under race loads
• 5mm inboard bullet tubes with 2mm balance tube
• Impact-resistant hardcase construction
• Shorty form factor — fits standard shorty battery compartments

Charge Rate

• 1C to 5C recommended — higher charge rates reduce mAh input and cycle life
• Requires a LiHV-compatible charger set to 4.35V/cell charge voltage
