ND2057 & ND3057 DESCRIPTION:
National Stock Number/NATO Stock Number: ND2057HD29 NSN: 6140015994701
The ND2057 and ND3057 are ideal for low temperature applications as the low internal impedance enables the cells to deliver good capacity and discharge current. The ND2057 can preforms as low as -10°C and the ND3057 has tested as low as -30°C (Note, in cases of low temperature applications, we strongly recommend all batteries be tested in the intended environment to discern specific performance levels). Also, with their 8A discharge capability, the ND2057 and ND3057 are ideally suited as a small “hot-swap” battery to hold up the device for a short period while the main battery is changed.
The ND2057 and ND3057 smart Li ion batteries can be customized to meet unique specifications. Maybe you’re looking for a label change to display your corporate livery? Or a firmware modification to the smart battery’s data? Or perhaps you need a performance change for the batteries? Creating custom-hybrids of standard batteries is a part of Inspired Energy’s established expertise.
