Performance Highlights
High capacity in a 6S format. The 66Ah nominal capacity provides about 1.56 kWh nominal energy, making this 23.7V lithium battery pack suitable for longer runtime and high-energy UAV/robotics platforms.
Strong discharge capability. The pack supports 3C continuous discharge (198A) and a 6C maximum discharge (396A). This makes it a candidate for high-power takeoff, climbing, acceleration, or short burst loads. System designers should confirm the 6C duration and thermal design with us.
Semi-solid lithium chemistry. The semi-solid lithium battery platform is specified for this model, with a nominal 6S voltage of 23.7V. Use a charger and BMS configured for the datasheet limits: 26.7V max charge and 16.5V minimum discharge.
Practical integration hardware. The pack is supplied with a QS8-S2 discharge connector and 6AWG discharge cables, plus an XH2.54-7PIN connector for signal/control wiring. The product image shows the compact black pack format and labeled model.
Recommended Applications
- UAV and drone battery packs
- Robotics and AGV power systems
- Portable high-current DC power
- Industrial battery packs requiring 6S 66Ah capacity
- Semi-solid lithium battery evaluation and prototyping
For flight applications, the datasheet notes that the aircraft should reserve sufficient voltage for return. Always size the pack, charger, and BMS with appropriate margin.
