PTK513322 2S 130C Low IR Si-Graphene + HV LiPo Battery (7.6V/9600mAh) w/5mm Connectors

ProTek RC PTK‑5133‑22 2S 130C HV LiPo Battery is likely what you’re referring to by PTK513322. It’s a high‑performance 2‑cell (2S) lithium‑polymer (LiPo) battery designed for radio‑controlled (RC) vehicles. This pack delivers 7.6 V nominal voltage and a large 9600 mAh capacity with a 130C discharge rating, meaning it can provide strong, consistent power and sustained voltage throughout a run — ideal for competitive racing or high‑load RC applications like 1/10 scale cars and trucks. The battery uses Silicon Graphene + High Voltage (HV) cell technology for improved efficiency, lower internal resistance, and cooler operation compared with standard LiPo cells, and comes with 5 mm bullet connectors for easy plug‑in use in compatible ESCs. 

Features:

• Lighter than a hardcase 2S LiPo pack of equal capacity
• More runtime, with a dramatic increase in voltage and punch
• Silicone Graphene can handle more abuse and deliver more current than a standard LiPo battery
• Improved efficiency, lower operating temperatures, and lower internal resistance!
• 10C max charge rates - 1C charge rate recommended for longest life
• Perfect for stock class racers looking to shave grams
