The NB2037QE34 is the IEC, UL, CSA 62133-2, BIS, KC & PSE approved model of the NB2037HD34 ( 2S1P ) 7.2V smart lithium ion battery which incorporates the standard features that designers and engineers have come to rely on for safety and function, such as SMbus , a pull tab for easy removal and on-pack LCD display for relative SOC indication. The Inspired Energy 203x range of rechargeable smart Li-Ion battery packs are ideally designed for use in compact and handheld devices.

The 2037 battery pack can perform at -20°C for low temperature applications, as the low internal impedance enable the cells to deliver good capacity and discharge current. (Note, in low temperature applications, we recommend testing the device at temperature to validate performance).

CH-series chargers are recommended for these batteries.

NB 2037 smart liIon batteries can be customized to meet unique specifications. SHA-1 secure handshake, custom label, custom firmware and additional performance options are available for OEM applications. Creating custom-hybrids of standard batteries is a part of Inspired Energy’s established expertise.

We suggest the NB3037HD29 as the higher discharge rate and lower temperature option. When additional capacity is needed, consider evaluation of the NB4037 .

The NB2037QE34 has been updated as a replacement for the previous NB2037HD29 and NB2037HD31 models.
