NXE 4200mAh 3S 11.1V 40C Soft Case LiPo Battery with Deans – 4200SC403SDEAN

The NXE 4200mAh 3S 11.1V 40C Soft Case LiPo Battery is a versatile high-capacity battery designed for RC models requiring reliable 3S LiPo power. With its combination of 4200mAh capacity, 40C discharge rating and factory-fitted Deans / T-Plug connector, it offers a strong balance of runtime, power delivery and manageable size.

The soft-case construction helps keep weight down compared with an equivalent hard-case battery, making it suitable for RC aircraft and other compatible electric RC applications where battery weight and space are important considerations.

4200mAh 3S Performance

The 4200SC403SDEAN uses a standard 3S LiPo configuration, providing 11.1V nominal voltage and reaching 12.6V when fully charged.

Its larger 4200mAh capacity provides increased potential runtime compared with the smaller 3300mAh NXE packs, making it a good choice where additional operating time is desired and the model can accommodate the extra battery size and weight.

With a 40C discharge rating, the pack has a theoretical continuous current capability of approximately 168A (4.2Ah × 40C), providing strong power delivery for compatible electric power systems.

Lightweight Soft Case Construction

The battery uses a soft-case construction, helping minimise unnecessary weight and bulk while providing a substantial 4200mAh capacity.

Published dimensions vary slightly between current Australian suppliers. One listing specifies 138 × 42 × 24mm and 332g, while another lists 135 × 43 × 24mm and 315g.

For the website, I would list the dimensions as approximately 138 × 43 × 24mm and the weight as approximately 315–332g, rather than giving an overly precise figure where supplier data differs.

Deans / T-Plug Connector

The 4200SC403SDEAN comes factory fitted with a Deans / T-Plug main power connector, making it ready to connect directly to compatible ESCs without needing to change the connector.

A JST-XH balance connector is also fitted, allowing the individual cells to be correctly monitored and balanced when using 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 LiPo batteries is required.

Always check that your model's ESC and motor are rated for 3S LiPo operation. Also confirm that the battery dimensions, weight and Deans/T-Plug connector are suitable for your model before installation.
