About this part
NB4037QE50 Smart Lithium-Ion Battery: The Inspired Energy 40xx range of rechargeable smart Li-Ion battery packs utilize 21700 cells and are designed for applications where size and runtime may be a consideration. The NB4037QE50 ( 2S1P ) 7.2V smart lithium ion battery incorporates the standard features that designers and engineers have come to rely on for safety and function, such as SMbus , a pull tab for easy removal and on-pack LED display for relative SOC indication. This battery is IEC, UL, CSA61233-2, and TUV certified compliant. The NB4037QE50 battery pack can perform at -20°C for low temperature applications, as the low internal impedance enable the cells to deliver good capacity and discharge current. (Note, in low temperature applications, we recommend testing the device at temperature to validate performance). The compact design makes it ideal for use in compact and handheld devices. Features: • SMbus • Pull tab for easy removal • On-pack LCD Display for Relative SOC Indication Our expertise lies in creating customized battery hybrids that seamlessly integrate standard components to deliver optimal performance.
