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 NB4037HD50 ( 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. The NB4037 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.

CH-1xxx series chargers are recommended for these batteries. NB 4037 smart liIon batteries can be customized to meet unique specifications. SHA-1 secure handshake, custom label, custom firmware and additional performance options are available for OEM applications.

Creating custom-hybrids of standard batteries is a part of Inspired Energy’s established expertise.
