Application notes
From the current catalog
ND4057HD50 Smart Lithium-Ion Battery: The 40xx range of rechargeable smart Li-Ion battery packs are designed for applications where size and runtime may be a consideration.
The ND4057HD50 (2S2P) 7.2V smartbattery incorporates the standard features that designers and engineers have come to rely on for safety and performance, such as SMbus, a pull tab for easy removal and on-pack LED display for relative SOC indication.
The 4057 battery pack can perform at -20°C for low temperature applications, as the low internal impedance enables 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.
ND4057HD50 Smart Li-ion battery customization options:
- Custom label
- Custom Firmware
- Additional performance options for OEM applications N-series chargers are recommended for these batteries.
