PTK-5131-22 ProTek RC 4S 130C Low IR Si-Graphene+ HV Shorty LiPo Battery (15.2V/6400mAh) w/5mm Connector (ROAR Approved)

ProTek RC 4S Shorty 15.2V 6400mAh 130C Graphene+ High-Voltage LiPo Battery

Compact Size. Massive Output. Built for 1/8 Scale Racing.

The ProTek RC 4S 6400mAh 130C Graphene+ HV Shorty LiPo Battery is designed for racers who need big power in a compact footprint. Weighing just 440g, this battery delivers more capacity than standard 4S packs in a shorter and lighter form factor—making it ideal for weight-conscious 1/8 scale builds.

Built using Silicon Graphene technology, this pack offers lower internal resistance, improved efficiency, reduced heat, and a flatter discharge curve. That means more consistent voltage and punch from start to finish—plus an extended cycle life when properly maintained.

⚙️ Key Features:

• Shorty-size 4S configuration – compact and lighter than traditional 4S packs
• 6400mAh capacity with 130C burst rating for extended runtime and aggressive throttle response
• Silicon Graphene cells – improved efficiency, longer lifespan, and lower heat buildup
• Lighter weight (440g) for optimized weight distribution and chassis tuning
• ROAR approved – ready for competitive racing
• Compatible with standard LiPo chargers (can also be charged to LiHV specs for full performance)
