The NB2037 and the NB3037 are ideal for low temperature operation as the low internal impedance enables the cells to deliver good capacity and discharge current. The NB2037 can perform as low as -10°C and the NB3037 has tested as low as -30°C. (Note, in cases of low temperature applications, we strongly recommend testing in your specific application). Also, with 8A discharge capability, the NB3037 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.
