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 perform 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 testing in your specific application). 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 charged. These smart Li-ion batteries can be customized to meet unique specifications. Custom label, custom firmware and some performance options are available. Creating custom-hybrids of standard batteries is a part of Inspired Energy’s established expertise.
