The ND2057HD34 is ideal for low temperature applications, as the low internal impedance enables the cells to deliver good capacity and discharge current. The 2057 battery pack can perform as low as -20°C (Note, in low temperature applications, we recommend testing the device at temperature to validate performance).

The CH-series charger is recommended for these batteries.

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.

For the IEC & UL 62133-2 approved model, we suggest the ND2057QE34

The ND2057HD34 has been updated as a replacement for the previous ND2057HD24 , ND2057HD29 , ND2057HD31 & ND2057XD24 (NSN # 6140-01-599-4701 & 6140-01-656-7575 ) models.
