Product Description
ProTek RC 2S 150C Low IR SG3 HV LiPo Battery (7.6V/10000mAh) w/5mm Connectors (ROAR Approved) (PTK-5133-26)
The ProTek RC 2S 150C Low IR SG3 HV LiPo Battery is engineered for dependable, high-output performance in demanding RC applications. With a massive 10,000mAh capacity, it is an excellent choice for endurance-focused formats such as dirt oval racing, where long run times and consistent voltage delivery are essential. Its Silicon Graphene Third generation (SG3) cell technology represents ProTek's evolution in high-voltage chemistry, offering improved efficiency and stability throughout each run.
High-Capacity Power & Reliability 
Built to deliver strong punch and smooth throttle response, this pack features low internal resistance (IR) for efficient power transfer under load. The extended cycle life ensures durability through repeated charge cycles and tough race conditions, making it a reliable option for racers who demand both performance and longevity. Whether you're chasing endurance, consistency, or overall power delivery, this SG3 battery provides the output and resilience needed to stay competitive.
NOTE: When using high energy Li-Polymer Batteries, please do not over-discharge or over-charge batteries as this will result in overheated batteries. Discharging capacity can't exceed 80% of the max capacity of the pack after full charging to ensure a good cycle performance. It is recommended to fully charge a brand new battery before using and only discharge the battery 50% for the first 5 cycles. Always monitor race time and/or set a low voltage warning on ESC (End voltage cannot be lower than 3.2v per cell). Do not use a battery that has too low a voltage. Do not expose batteries to sunshine or store/charge batteries at temperatures above 35°C or in a closed car. The high-temperature environment could cause damage to the pack or make it burst. If the battery becomes hot while fast charging, high current discharging, or racing, do not charge it until it has cooled completely. Wait about 20 mins, then inspect prior to recharging.
