The 40xx range of rechargeable smart Li-Ion battery packs are designed for applications where size and runtime may be a consideration. The ND4057HD50 (2S2P) 7.2V smartbattery incorporates the standard features that designers and engineers have come to rely on for safety and performance, such as SMbus, a pull tab for easy removal and on-pack LED display for relative SOC indication. The 4057 battery pack can perform at -20°C for low temperature applications, as the low internal impedance enables the cells to deliver good capacity and discharge current. (Note, in low temperature applications, we recommend testing the device at temperature to validate performance).

The CH-1xxx series chargers are recommended for these batteries, as represented below in the Compatible Charger section of this page.

ND4057 smart liIon 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. You are welcome to work directly with our technical, engineering and manufacturing staff here at our headquarters in Newberry, Florida. We currently ship our products to over 96 countries.

We suggest the NB4037HD50 (2S1P) when a smaller format is needed and the NH2057QE34 (2S4P) for additional rated capacity. Alternatively, we offer the ND4054HD50 (4S1P) as a 14.4V option.
