14.4V 5.7Ah (82.08Wh) Lithium Ion Battery
The SE20542NR29 is a 14.4V 5.7Ah (82.08Wh) Lithium ion smart battery which can be designed into a wide range of products and equipment. The battery comprises eight 3.6V 2.85Ah 18650 cells in a 4-series, 2-parallel array and can deliver up to 6A 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 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 LED display on the top of the battery provides the user with an easy way of viewing remaining battery capacity in 20% segments.
The SE20542NL29 meets the requirements of UN38.3 (transportation), is CE marked and RoHS / WEEE compliant.
