NB2037HD29

7.2V 2.9Ah (20.9Wh) Lithium Ion Battery (<3.0A capable)

Status: 'Active' - Recommended for new device developments.

The NB2037HD29 is a 7.2V 2.9Ah (20.9Wh) Lithium ion smart battery which can be designed into a wide range of products and equipment. The battery comprises two 3.6V 2.9Ah 18650 cells in a 2-series, 1-parallel array and can deliver up to 3A of discharge current. The internal battery management system (BMS) is System Management Bus (SMBus) and Smart Battery System (SBS) compliant and can operate as part of a smart battery system along with a compatible smart charger and host device. The BMS provides cell and battery level protection against over-voltage, under-voltage, over-current, short-circuit and over-temperature. The communication interface allows a host device to read pertinent battery data such as Runtime to Empty (minutes), Full Charge Capacity (mAh) and Relative State of Charge (%) which are provided by the impedance tracking fuel gauge. In addition, a wealth of other calculated and static data is available making the battery an active part of any power management system. When connected to a smart charger, the battery broadcasts its required Charging Voltage (mV) and Charging Current (mA) which the charger provides until commanded to stop charging.

Externally, the battery has a UL94V-0 rated black plastic enclosure and features an industry standard 5-way connector interface for power and communication. Both right angled and vertical mating connectors are available as accessories. A 5-segment LCD display on the end of the battery provides the user with an easy way of viewing remaining battery capacity in 20% segments.

The NB2037HD29 meets the requirements of UN38.3 (transportation), is CE marked and RoHS / WEEE compliant. If your end device requires the battery to be certified to IEC 62133 or of you require CSA/UL certification then please consider the NB2037QE34.

The NB2037HD29 has Inspired Energy livery as standard, however custom labelled versions of the battery can be created to meet your specific requirements. Customisation can include bespoke artwork, special regulatory certification or SHA-1 encryption, please contact us to discuss customisation of the NB2037HD29.
