6.4V 18Ah 32700 Battery Pack FAQs
What’s the maximum discharge current? Is there a peak current rating?
The battery supports a continuous discharge current of up to 10A, and it can handle peak currents up to 15A for short durations (<10 seconds). This makes it suitable for devices requiring stable power like amplifiers and surveillance systems.
Can it be used in cold or high-temperature environments?
Yes. The standard operating temperature range is -4°F to 140°F (-20°C to 60°C).
For extreme cold environments, we also offer low-temperature versions that operate down to -22°F (-30°C), suitable for winter, forest, or high-altitude deployments.
Can I customize the pack for my device?
Yes. We support customization of wiring, connectors, casing, communication interface, and mounting structure to fit your system requirements. Contact our engineering team for OEM/ODM collaboration.
