Semi-Solid State Drone Battery Pack

Unlike high-density liquid LiPo batteries that suffer from severe voltage sag under load, YIHANG factory’s Semi-Solid State Drone Battery Pack maintains exceptionally flat discharge curves during high-throttle maneuvers.

Semi-Gel Electrolyte Matrix: Reduces internal resistance (Ri) and eliminates free liquid, mitigating thermal runaway and swelling risks under continuous high-current discharge.

Sustained Power Output: Prevents voltage drop at high SOC/load transitions, ensuring stable motor thrust from launch to landing.

Ruggedized Structural Housing: Encased in an aluminum alloy enclosure to maximize impact resistance and heat dissipation without adding redundant dead weight.

Integrated Smart BMS: Continuously monitors per-cell voltage, current, internal resistance, and multi-point temperatures via real-time CAN Bus or RS485 communication.

Why Choose YIHANG for Your Semi-Solid Battery

Semi-Solid Battery Development YIHANG focuses on semi-solid battery pack development for industrial UAV applications requiring higher energy density and controlled high-current output.

Smart BMS Integration BMS hardware, firmware configuration, balancing, protection, and CAN/RS485 communication can be adapted to the target UAV system.

Flexible Engineering Voltage, capacity, dimensions, C-rate, connectors, and communication parameters can be configured around the aircraft rather than a fixed battery format.

Reference Configurations Existing 6S–28S configurations provide starting points for UAV evaluation and application development.

Application-Based Validation Battery specifications and BMS functions can be checked against the agreed electrical, mechanical, and communication requirements.

FAQ

What is a Semi-Solid State Drone Battery Pack?

It is a UAV battery pack using a semi-solid electrolyte cell structure together with an integrated BMS. The configuration is intended for applications requiring a combination of energy density, high-rate output, and battery management.

What voltage configurations are available?

The listed configurations cover 6S to 28S, including 12S, 14S, 16S, 18S, 24S, and 28S reference models.

What capacity range is available?

Reference models range from 4000mAh to 50000mAh, while customized capacities from 4000mAh to 60000mAh can be evaluated according to the battery configuration.

Does the battery support CAN and RS485?

Yes. CAN and RS485 communication are available for compatible UAV flight-control, ground-station, and monitoring systems.

How many cycles can the battery achieve?

The stated reference is 1000 cycles to 80% initial capacity under the specified test conditions: 25°C ±2°C, 1C charge, 2C discharge, and 100% depth of discharge. Actual cycle life depends on operating and charging conditions.
