E-Bike Battery Compatible With Panasonic Motor Systems - Long Range Replacement

The **GEB-PAN-E25.2B** is a premium third-party replacement battery designed specifically for Panasonic e-bike systems running on 25.2V. Engineered with high-quality **Li-ion 18650 2600mAh cells**, this pack offers an impressive nominal capacity of **20.8Ah**, providing extended range for daily commuting or touring.

It features the classic silver casing design with a robust carrying handle and a clear LED remaining power indicator, ensuring seamless integration and ease of use comparable to the original battery.

Safety and reliability are ensured through a combination of an advanced Battery Management System (BMS) and robust hardware protection. The inclusion of a **40A slow-blow fuse** provides ultimate fail-safe protection against short circuits.

Precise BMS Monitoring Points:

• Over-Voltage Protection: Cell cut-off at 4.3V.
• Under-Voltage Protection: Cell cut-off at 2.3V, with a pack discharge termination at 17.5V.
• High-Load Management: Over-current protection set at 33A ±3A with a 3000ms delay, allowing for temporary high-torque demands without nuisance tripping.
• Comprehensive Thermal Safety:
  • MOSFET Over-temperature: 100°C (3s delay).
  • Charge Over-temperature: 50°C (3s delay).
  • Discharge Over-temperature: 60°C (3s delay).

Reliable Power Output:
With a low internal resistance of ≤100mΩ, the battery delivers a standard continuous discharge current of 12A, capable of sustaining a maximum continuous load of 20A.

Charging Recommendations (CC/CV Mode):
To maximize service life, we recommend a slow charge rate of 1.8A. For quicker turnaround, fast charging up to 2.5A is supported, with a maximum permissible input of 5A.

Operating Conditions:
Designed for diverse climates, the battery can discharge safely in temperatures ranging from -20°C to +40°C. Charging should occur between 0°C and +40°C. Maximum humidity should not exceed 85%.

Produced by General Electronics Technology Co., LTD., this replacement battery undergoes rigorous testing to ensure capacity consistency and BMS functionality. We offer B2B wholesale pricing and can provide customized solutions for distributors requiring specific branding or configurations.
