UBI-2590 LE SMBus

The UBI-2590 LE SMBus (Ultralife part number UBBL38) is a smart rechargeable Lithium ion version of the primary BA-5390A/U battery. It is the highest non-class 9 energy possible in a BB-2590 package.

The UBBL38 contains two independent battery sections which can be connected in either series or parallel.

In 30V 'series mode' the battery operates between 33.6V and 20.0V (28.8V average) and delivers 2.9Ah. In 15V 'parallel mode' the battery operates between 16.8V and 10.0V (14.4V average) and delivers 5.8Ah.

The UBBL38 features dual LCD displays which indicate the absolute state of charge for each section. Ultralife's SmartCircuit technology allows compatible devices and chargers to communicate with the battery via its SMBus v1.1 compliant interface.

The UBBL38 can be used in a wide range of rugged, portable electronics, robotics, AUV / UUB and military communication devices.
