The ProTek RC 7.6V 2600mAh HV LiPo Hump Receiver Battery is a high-voltage receiver pack designed to provide dependable power for compatible RC receivers and high-voltage servos. Its compact hump-style configuration is specifically suited for applications with limited battery-box space, including compatible Kyosho and Tekno 1/8 scale nitro vehicles.
Featuring a 2S2P LiHV configuration, 2600mAh capacity, and an 8C continuous discharge rating, the PTK-5502 can deliver up to 20.8A of continuous current. This makes it well suited for modern high-performance servo systems where strong current delivery and consistent voltage are important.
The PTK-5502 uses high-voltage LiPo chemistry with a nominal voltage of 7.6V.
When paired with compatible high-voltage receiver electronics and servos, the increased voltage allows HV servos to take advantage of their higher-voltage speed and torque capabilities.
A 2600mAh capacity provides substantial runtime for receiver and servo electronics while maintaining the compact dimensions needed for nitro RC applications.
This makes the pack suitable for racing, practice sessions, and other applications where reliable receiver power is essential.
The battery features an 8C continuous discharge rating, providing up to approximately 20.8 amps of continuous current.
This current capability helps support high-performance steering and throttle servos, particularly during situations where both servos may place significant demand on the receiver battery.
The battery cells are surrounded by a Lexan plastic shell and then covered with heat shrink.
This protective construction helps shield the cells from impacts and other stresses encountered inside an RC vehicle while maintaining a relatively lightweight package.
Because there is a small air space between the cells and protective Lexan shell, the outside of the pack may feel slightly soft when pressed. This is normal for this battery's construction.
Measuring approximately 54 x 32 x 31mm, the battery uses a compact hump-style layout designed to fit compatible battery compartments.
It is particularly suited for Kyosho and Tekno 1/8 scale battery boxes, while its size also makes it useful for other compatible nitro vehicles and receiver-powered applications.
The main power lead uses a JR-style connector with 20AWG silicone wire for connection to compatible receiver electronics.
An XH-style balance connector is also included for proper balance charging with a compatible LiHV/LiPo charger.

NOTE: This is a high-voltage LiPo receiver battery. Verify that your receiver and servos can safely operate at the battery's voltage before use. A suitable voltage regulator is required when powering electronics that are not rated for the battery's maximum voltage.
LiPo SAFETY: Always use a compatible LiPo/LiHV balance charger and charge the battery in a LiPo-safe charging bag. Never leave the battery unattended while charging, and do not charge the battery while it is installed in the vehicle.
