Application notes

From the current catalog

NH2057HD34 Smart Lithium-Ion Battery: The NH2057HD34 is ideal for low temperature applications, as the low internal impedance enables the cells to deliver good capacity and discharge current.

The 2057 battery pack can perform as low as -20°C (note, in low temperature applications, we recommend testing the device at temperature to validate performance).

Also, with its’ 8A discharge capability, the NH2057 is ideally suited as a small “hot-swap” battery to hold up the device for a short period while the main battery is charged.

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.
