10.8V 3.4Ah Lithium Ion Battery (NC2040QE34)

The NC2040QE34 is a 10.8V 3.4Ah (37Wh) Lithium-ion smart battery which can be designed into a wide range of products and equipment. The battery comprises three 3.6V 3.4Ah 18650 cells in a 3-series, 1-parallel array and can deliver up to 4A 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 a 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 the remaining battery capacity in 20% segments.

The NC2040QE34 meets the requirements of UN38.3 (transportation), IEC 62133-2, and UL/CSA 62133. The battery is also CE-marked and RoHS / WEEE compliant. If your end device does not require the battery to have IEC or UL/CSA certification then we recommend the NC2040HD34.

The NC2040QE34 has Inspired Energy livery as standard, however, custom-labeled 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.
