NXE 450mAh 3S 11.1V 30C Soft Case LiPo Battery with JST – 450SC303SJST

The NXE 450mAh 3S 11.1V 30C Soft Case LiPo Battery is a compact and lightweight power pack designed for small RC aircraft and other electric models where battery size and weight are critical.

Featuring a 450mAh capacity, 30C discharge rating and factory-fitted JST connector, this battery provides 3S performance in a very small package. It is particularly useful for lightweight models that require the extra voltage of a 3S battery without the size and weight of a larger-capacity pack.

Compact 3S Power

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

Its 450mAh capacity keeps the battery compact and lightweight, while the 30C continuous discharge rating provides suitable current delivery for compatible small electric power systems.

Published NXE specifications also list a 60C burst discharge rating, allowing additional short-duration current delivery when required.

Lightweight Soft Case Design

The soft-case construction keeps weight to a minimum, making this battery particularly suitable for small RC aircraft where even a few grams can affect balance and flight performance.

NXE distributor information lists the battery at approximately 56 × 30 × 15mm and 42g. Some Australian retailers list slightly different measurements of 47 × 30 × 14mm and 46g, so minor variations may exist between production batches or measurement methods.

For the website, I would use the distributor specification of 56 × 30 × 15mm and approx. 42g.

JST Connector

The 450SC303SJST comes factory fitted with a JST main power connector, a compact connector commonly used on smaller RC aircraft and electric models.

A JST-XH balance connector is also fitted, allowing all three cells to be individually monitored and balanced when charging with a compatible LiPo balance charger.

Please Note

This is a standard 3S 11.1V LiPo battery, not a LiHV battery. A suitable LiPo balance charger capable of charging 3S batteries is required.

Always confirm that your model's ESC and motor are rated for 3S / 11.1V LiPo operation. Also check the JST connector type and battery compartment dimensions before installation.
