About this part
NC4040QE50 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 NC4040QE50 (3S1P) 10.8V 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. The NC4040 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). Designed for use in compact and handheld devices, this battery is IEC, UL, CSA 62133-2, & BIS approved to meet the highest industry standards for safety and performance. 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. NC4040QE50 Smart Li-ion battery customization options: • SHA-1 secure handshake • Custom label • Custom Firmware • Additional performance options for OEM applications N-series chargers are recommended for these batteries.
