Application notes

From the current catalog

Ni2040QE29 Smart Lithium-Ion Battery: The Ni2040 is ideal for low temperature applications as the low internal impedance enables the cells to deliver good capacity and discharge current.

The Ni2040 can perform as low as -10C (note, in cases of low temperature applications, we strongly recommend testing in your specific application).

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.

Ni2040QE29 Smart Li-ion battery customization options:

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

The Ni2040QE29 is our newest model, designed to outperform the previous Ni2040QE24, Ni2040A24 and Ni2040QE29 (with a lower current of 8A).

Custom options
