UltraLife UBI-2590 Commercial Rechargeable BatteryDual Output ModesThe UltraLife UBI-2590 High Capacity battery is a designed for robotics and military use. This rechargeable Lithium Ion (Li-Ion) battery offers a unique dual output capability. There are two individual batteries in one dense plastic case. When using both of the batteries at the same time there is an extremely high capacity of 10Ah and an output of 30V. You as the user also have the choice of running one battery at a time, instead of the dual output, and having an even higher capacity of 20Ah! It shouldn't be extremely difficult to find a battery that has such high outputs - and it no longer is with the UBI-2590. This Li-Ion battery features SmartCircuit Technology. The SmartCircuit allows the host and the charging equipment to communicate and prevent from over- or under-charging.Several Technical ApplicationsThe UBI-2590 battery pack works great in multiple types of electronics. The durable plastic case surrounding the batteries makes it perfect for tactical use because it can withstand the harsh environment. Military users will typically use this battery for AUVs, UUVs, and other types of communication devices! The high capacity battery is also used for robotics and different types of portable electronics. Additionally, this light comes with a state of charge LCD status indicator. You will no longer have to guess how much charge is left in your battery!Features:SMBus to Communicate With Host and Charging EquipmentThe Battery Case is Constructed of a Sturdy PlasticAn Accurate State-Of-Charge Display For Each Side of the BatteryOptional Dual Voltage OutputCertifications:MIL-PRF-32383/3UN 38.3IEC 62133:2012Specifications:Battery Size: Battery PackBattery Chemistry: Lithium Ion (Li-Ion)Nominal Voltage: 30VNominal Capacity: 10AhMax Charging Current: 4.8ARecommended Charging Current: 3.0ARecommended Charger: UltraLife UCA0114Estimated Charge Cycles: 300 cyclesMax Discharge Current: 10AOperating Temperature Range: -25.6°F to 140°F (-32°C to 60°C)Dimensions:Length - 4.43" (112.52 mm)Width - 2.48" (62.99 mm)Height - 5" (127 mm)Weight: 48.68oz.
