41AQ586 (خلايا ليثيوم أيون 18650 بثلاث أقطاب وثلاثة أقطاب)
The 41AQ586 is well-suited for low-temperature applications, as it can operate at temperatures as low as -20°C. A key note: for low-temperature use cases, we strongly recommend conducting tests within your specific application to confirm it meets performance needs. Additionally, with an 8A discharge capability, this battery works perfectly as a compact “hot-swap” battery, keeping the device running for a brief period while the main battery is being charged.
