41AQ529
The 41AQ529 is well-suited for low-temperature applications, thanks to its low internal impedance—this feature allows the cells to maintain good capacity output and stable discharge current even in cold environments.
The 41AQ529 can operate reliably at temperatures as low as -30°C. A key note: for low-temperature use cases, we strongly recommend conducting performance testing in your specific application scenario to ensure it meets your needs. Additionally, with its 10A discharge capability, the 41AQ529 works perfectly as a small “hot-swap” battery; it can keep the device running for a short period while the main battery is being charged.
