NXE 850mAh 3S 11.1V 30C Soft Case LiPo Battery with JST – 850SC303SJST

The NXE 850mAh 3S 11.1V 30C Soft Case LiPo Battery is a compact and lightweight power pack designed for smaller RC models requiring the extra performance of 3S LiPo power without the size and weight of a larger battery.

Featuring an 850mAh capacity, 30C discharge rating, lightweight soft-case construction and factory-fitted JST connector, this battery is particularly well suited to small electric aircraft, EDF models and other compact RC applications. Australian NXE listings classify this pack primarily for air use.

Compact 3S LiPo Power

The battery uses a 3S LiPo configuration, providing 11.1V nominal voltage and reaching 12.6V when fully charged.

Compared with a similar-capacity 2S battery, the 3S configuration provides a higher operating voltage, making it suitable for compatible models that require the additional power and motor speed available from an 11.1V battery.

The 850mAh capacity provides a useful balance between runtime and weight, particularly in smaller aircraft where keeping overall flying weight down is important.

30C Discharge Rating

The 30C discharge rating provides reliable current delivery for compatible electric power systems while maintaining the compact dimensions required by smaller models.

This makes the battery a practical choice for small sport aircraft, EDF jets, park flyers and other lightweight RC models designed specifically for 3S operation.

Lightweight Soft Case Construction

The 850SC303SJST uses a lightweight soft-case construction, helping minimise unnecessary weight and allowing the battery to fit into relatively small battery compartments.

Published dimensions vary slightly between suppliers. NXE retailers list approximately 58–60mm long, 30mm wide and 21–23mm high, with a weight of approximately 69–73g.

JST Power Connector

The battery comes factory fitted with a JST main power connector, commonly used on smaller electric RC models.

A separate XH balance connector is provided for monitoring and balancing the individual cells during charging.

Please Note

This is a standard 3S 11.1V LiPo battery and requires a LiPo-compatible balance charger capable of correctly charging 3S batteries.

Before use, confirm that your model's ESC and motor are rated for 3S LiPo operation, that it uses a compatible JST connector, and that the battery compartment can accommodate the pack.
