36V 14Ah 18650 10S4P Lithium-ion Battery Pack for Mobility Devices
A mobility devices manufacturer required a compact, high-performance 36V lithium-ion battery pack to power their next-generation mobility device. Their previous supplier was unable to meet critical requirements for size, cycle life, and electrical safety. The client needed a fully customized solution—both electrically and mechanically—that could integrate seamlessly into a tightly constrained battery compartment.
CM Batteries developed a bespoke 36V 14Ah lithium-ion battery pack using high-quality Samsung 18650 35E cells.The delivered battery pack integrated perfectly into the client’s device, meeting all dimensional, performance, and safety specifications. The solution enabled the manufacturer to proceed with product launch confidently, backed by a power source that matched their innovative design and stringent quality standards.
Key features：
- Built with 40pcs Samsung 18650 35E cells, delivering a nominal 36V and 14Ah capacity while maintaining a precise custom dimension of 40 × 67 × 370 mm.
- Equipped with a 15A BMS offering full electrical safety, including over-charge, over-discharge, over-current, and short-circuit protection.
- Supports a maximum continuous charging current of 5A, ensuring efficient charging while protecting battery health.
- Reliable Cycle Life: Over 500 cycles.

10S4P 36V 14Ah 18650 Battery Pack FAQs
Can this battery pack be adapted to fit our existing mobility device enclosure?
Yes. Mobility devices usually have strict internal space limitations due to frame design and weight distribution. We can adjust pack length, width, height, cable direction, and connector type to ensure seamless integration with your device’s current mechanical structure.
What if our device requires higher peak current for motor startup or climbing inclines?
We frequently customize discharge capabilities for mobility systems with high inrush or peak torque demands. Share your motor controller’s current profile and load curves—we will match your peak and continuous current needs.
Can you provide the battery with certifications required for mobility devices?
Yes. We provide UN38.3 test reports for shipping compliance, and can also assist with IEC62133 or UL2054 certification processes based on your project needs. Certification execution is coordinated together with your final product testing.
What is the expected cycle life for a mobility-use battery, and how does usage affect it?
This cases is for 500+ cycles to 80% capacity under standard conditions. Cycle life depends heavily on load intensity, charging habits, and operating temperature.We provide usage recommendations to help understanding lithium ion battery life cycle and how to extend it.
