The ND2057 is 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 (Note, in cases of low temperature applications, we strongly recommend testing in your specific application). Also, with its' 8A discharge capability, the ND2057 is 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.
