SPIDER Automation | Bonka 3S 11.1V 850mAh 25C Lithium Polymer Battery Pack | Compact Power Delivery for FPV & RC Systems
Product Overview & Battery Technology
The Bonka 11.1V 850mAh 25C 3S Lithium Polymer Battery Pack is a rechargeable power solution developed for compatible radio-controlled and electronic systems. Its three-cell configuration provides an 11.1V nominal output, while the 850mAh capacity offers stored energy for equipment designed around this battery specification.
With a 25C discharge rating, the battery is intended for applications that require responsive power delivery. Its compact construction, measuring 57 × 30 × 20mm, makes it suitable for equipment with limited battery installation space, provided the electrical and physical requirements of the system are met.
The pack features two dedicated connectors: a T-Connector discharge plug for the main power connection and a JST-XH balance plug for cell-balancing operations. These connectors serve different purposes and should be used with compatible equipment.
Bonka lithium polymer batteries are designed for demanding RC and FPV applications. This particular 3S battery configuration can be considered for compatible drones, RC vehicles, airplanes, helicopters, multirotors and robotics systems.
