SPIDER Automation | Bonka 3S 4200mAh Hardcase LiPo Battery – 11.1V, 45C | High-Discharge Power for RC Systems
Product Overview & Hardcase Battery Design
The Bonka 11.1V 4200mAh 45C 3S Hardcase Lithium Polymer Battery Pack is designed for compatible radio-controlled vehicles and electronic power systems that require a rechargeable battery with a high discharge rating. Its three-cell series configuration provides a nominal voltage of 11.1V, while the 4200mAh capacity supplies stored energy for equipment designed around these battery specifications.
With a specified 45C discharge rating, this battery is intended for applications that demand high-rate power delivery. Its hardcase construction features a rigid outer enclosure around the battery pack, making it suitable for installations where a housed battery format is required. Actual operating performance depends on the connected equipment, current consumption, battery condition and operating environment.
The battery is equipped with a T-Connector discharge plug for the main power connection and a JST-XH balance connector for cell balancing during charging. These connectors provide separate interfaces for power delivery and balance charging with compatible equipment.
Measuring 135 × 45 × 35mm, the pack can be evaluated for RC vehicle battery compartments and other installations with sufficient clearance. Verify the available space, voltage requirements, connector polarity and discharge requirements of the intended equipment before use.
