Application notes

From the current catalog

The NC2040 10.8V 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).

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.

NC2040QE34 Smart Li-ion battery customization options:

  • Custom label
  • Custom Firmware
  • Additional performance options for OEM applications N-series chargers are recommended for these batteries.
