The U.S. Army Communications-Electronics Research, Development and Engineering Center’s Command, Power and Integration Directorate Power Division is developing solar arrays to improve the Soldier’s agility on the battlefield while meeting the demand of an increased power burden.

As C4ISR capabilities increase, Soldiers are forced to carry more batteries and power sources to support their mission. The BA-5790 Lithium Carbon Monofluoride (Li-CFx)/Lithium Manganese Dioxide (Li-MnO2) hybrid battery provides twice the energy of the non-rechargeable military standard BA-5590/U Lithium Sulfur Dioxide battery in the same size and weight.

This high energy density non-rechargeable battery allows the user to carry less batteries to complete the mission, therefore increasing Soldier’s mobility and lethality.


  • High energy density battery
  • Reduces the need to carry large quantities of spare batteries, therefore reducing carried weight and increasing mobility
  • Ruggedized, waterproof
  • Corrosion resistant
  • Has a complete discharge device with LED indicator


  • Capacity: 30Ah at 12VDC; 15Ah at 24VDC
  • Max Energy: 400Wh
  • Max Voltage: 16.5VDC or 33.0VDC
  • Discharge: 4.0Amps continuous at 15VDC; 2.0Amps
  • continuous at 30VDC
  • Size: 4.4 in. x 2.4 in. x 5 in.
  • Weight: 2.89 lbs. (max)
  • Operating Temperature: -22 degrees F to +132 degrees F (-30 degrees C to +55 degrees C)
