Frequently Asked Questions

What is the difference between an 18650 and 21700 battery pack?

21700 cells are physically larger than 18650 cells and may support a different capacity or output target. The suitable format depends on the required voltage, runtime, peak load, pack dimensions and cell availability for the project.

Can ASOL customize voltage and capacity for a cylindrical battery pack?

Yes. Series and parallel configuration can be evaluated around the required voltage, capacity, current and available space, subject to the final battery specification and project review.

Which BMS, connector and wiring options are available?

Protection limits, temperature sensing, wire gauge, connector type, harness layout, labels and selected communication needs are reviewed with the device and charger requirements.

What applications use custom cylindrical lithium battery packs?

Common applications include robotics, cleaning equipment, portable instruments, smart devices, lighting, power tools and industrial equipment. Each application requires its own load, charging and mechanical review.

What information is needed for an OEM battery pack quotation?

Please send the existing battery label or drawing, voltage, capacity or runtime target, normal and peak current, charger details, maximum size, connector, operating environment and estimated quantity.
