25.9V 14.5Ah Lithium ion 18650 Mobility Battery Pack for Mobility Vehicles
To make battery pack systems that work well in mobility-powered cars, engineers have to be very careful. The batteries must be small, have stable high-current discharge, be resistant to vibration, and have a consistent runtime. Many makers have trouble finding the right balance between safety, durability, and energy density when they are working with limited mechanical space.
This case showcases how CMB developed a custom 25.9V 14.5Ah 7S5P lithium-ion battery pack tailored for mobility applications, ensuring stable power delivery and long-term performance.
Key features：
- 7S5P design using 35 high-quality 2900mAh 18650 cells
- 15A continuous, 25A peak discharge BMS
- Strong vibration resistance for mobility applications
- Compact dimensions optimized for restricted compartments
- Anderson connector for plug-and-play integration
- Long cycle life and stable energy output
