41AQ533 Smart Li-ion Battery
The 40xx Series rechargeable smart Li-ion battery packs are designed for applications requiring a balance of compact size and long runtime.
The 41AQ533 (5S1P) 18V smart battery integrates the safety and functionality features engineers rely on, including:
• SMBus communication
• Convenient pull tab for easy removal
• On-pack LED display for relative State of Charge (SOC) indication
The 41AQ533 pack operates reliably in low-temperature environments down to −20°C.
Its low internal resistance ensures strong capacity retention and discharge performance even in cold conditions.
(Note: For low-temperature applications, performance validation at the actual operating temperature is recommended.)
Well-suited for handheld devices, portable instruments, and systems with limited space.
