ProTek RC PTK-5161 2S LiPo Receiver Battery 7.4V 2600mAh – Kyosho/Tekno

The 2600mAh capacity provides excellent runtime, while LiPo technology maintains a higher voltage under load compared with conventional NiMH receiver batteries. This is particularly useful with powerful steering and throttle servos, helping maintain consistent servo speed and performance throughout the run.

The battery cells are protected by a Lexan shell covered with heat shrink for additional protection inside the vehicle. Power is delivered through a JR-style connector with heavy-duty 20AWG silicone wire, while an XH-style balance connector allows the cells to be properly balance charged.

Important LiPo Receiver Battery Information

A fully charged 2S LiPo battery reaches 8.4V. Your receiver and servos must be compatible with this voltage. If the electronics are not designed for direct 2S LiPo operation, a suitable voltage regulator must be used.

Always charge the battery using a LiPo-compatible charger with balance charging enabled. Do not overcharge or over-discharge LiPo batteries.

The ProTek RC PTK-5161 is an excellent choice for racers and hobby drivers looking for a compact, lightweight and high-capacity receiver battery for a 1:8 nitro model. Its 2600mAh capacity, protective construction and Kyosho/Tekno-compatible form factor make it a practical upgrade from a traditional NiMH receiver pack.
