SPIDER Automation | Bonka 3S 11.1V 5200mAh 45C Hardcase LiPo Battery Pack | Protective Enclosure & Responsive Power Delivery
Product Overview & Hardcase Battery Technology
The Bonka 11.1V 5200mAh 45C 3S Hardcase Lithium Polymer Battery Pack is a rechargeable power solution designed for compatible radio-controlled vehicles and electronic systems. Its three-cell series configuration provides an 11.1V nominal voltage, while its 5200mAh capacity supplies stored energy for equipment designed around this battery specification.
This battery features a hardcase outer enclosure that provides a protective housing around the internal battery cells. The enclosed construction is useful in installations where a rigid outer casing is preferred over an exposed soft-pack format. It does not eliminate the need for careful handling or protection against impact, puncture and excessive heat.
With a 45C discharge rating, the pack is intended for applications requiring a suitable high-discharge battery configuration. Its electrical connections include a T-Connector discharge plug for the main power connection and a JST-XH balance plug for cell-balancing operations using a compatible charger.
The battery measures 135 × 45 × 35mm. Confirm the available battery compartment, connector arrangement and electrical requirements of the equipment before installation.
