The NC2040 and NC3040 are ideal for low temperature applications as the low internal impedance enables the cells to deliver good capacity and discharge current. The NC2040 can preforms as low as -10°C and the NC3040 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 its 8A discharge capability, the NC3040 is ideally suited as a small “hot-swap” battery to hold up the device for a short period while the main battery is changed.

The NC2040 and NC3040 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 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.

P-Series batteries use a high-current, 7-pin D-sub connector. They are more rugged than the N-Series batteries - some of them are IP65-rated - they also are optimized for using cells with low internal impedance which excel in low temperature and high discharge current applications. They require the use of a "PH" series charger.
N-Series batteries use a 5-blade standard battery connector. They are optimized for using high capacity cells for maximum runtime. They require the use of a "CH" series charger.
