Take your RC racing performance to the next level with the ProTek RC Spencer Rivkin Edition 2S 150C Low IR SG3 HV ULCG Shorty LiPo Battery (PTK-5143-26). Developed in collaboration with two-time IFMAR World Champion Spencer Rivkin, this premium high-voltage battery is engineered for competitive RC racers who demand consistent power delivery, low internal resistance, improved efficiency, and precise chassis handling.

Featuring advanced third-generation Silicon Graphene (SG3) cell technology, a 150C peak discharge rating, and an ultra-low center of gravity (ULCG) design, this 4900mAh shorty LiPo battery delivers powerful performance in a lightweight, compact package.

Advanced SG3 Silicon Graphene Technology

The ProTek RC Spencer Rivkin Edition battery features advanced SG3 Silicon Graphene cell technology designed to deliver low internal resistance, consistent voltage, and efficient power delivery.

Its high-voltage 7.6V configuration provides additional voltage potential compared to conventional 7.4V LiPo batteries, while its 150C peak discharge capability delivers the power needed for demanding competitive racing applications.

The low internal resistance design also helps reduce heat buildup and maintain consistent performance throughout your race.

Ultra-Low Center of Gravity Design

Designed with an ultra-low center of gravity (ULCG) shorty configuration, this battery helps improve chassis balance, weight distribution, and overall handling.

The compact shorty design provides flexibility when positioning electronics and adjusting vehicle balance. Its specially designed recessed pocket on the underside accommodates optional ProTek RC battery weights, allowing racers to fine-tune chassis balance and lower the center of gravity even further.

Compatible optional battery weight sets:

• ProTek RC PTK-5077 (10g, 20g & 30g).
• ProTek RC PTK-5078 (25g, 35g & 45g).

Battery weights are sold separately.
