When the mission calls for a dependable, high energy, safe and rapidly rechargeable battery technology for Launch vehicles, Missiles, Hypersonic Vehicles, Strike Weapons, Interceptors, Reentry Vehicles, Small Satellites and UAS/RPA, look no further than SIL’s. Li-Ion Polymer (Li-P) Intelli-Pack® Batteries.  Li-P Intelli-Pack® batteries offer increased power and reliability in a smaller, lighter package and built in advanced Battery Management System (BMS) that is agnostic to Li-Ion cell chemistry.  SIL’s BMS protects, balances and monitors each Li-Ion cell within the battery to ensure safety.  Battery packs meet or exceed the environmental levels of most aerospace applications for shock, vibration, thermal cycle and vacuum.  SIL’s Li-P Intelli-Pack® batteries come with custom Windows GUI and Data Logger software for turn-key battery field charge/discharge operations using a COTS power supply with current limit.  Inflight, you can monitor the overall battery state of charge, individual cell voltage, temperature, and charge/discharge current to reduce life cycle cost.  Li-P Intelli-Pack® batteries use modular, scalable and flexible design to meet customer battery voltage, capacity (1-200 Amp-Hour) and/or size requirements.  Li-P Intelli-Pack® batteries are easy to integrate into customer applications and SIL is committed to providing customer support through the design, integration, and operational project phases.


  • High energy density:
    • 3x energy density of Ni Cadmium batteries
    • 6x energy density of Lead-Acid batteries
    • 2x energy density of Silver Zinc and Ni-Metal Hydride batteries
  • Safe
  • Rapid Rechargeability (< 1 hour at 1C charge rate from dead state)
  • Minimal Heat Rise (very low cell impedance, < 3 mohm for 10Ah Cell)
  • Superior performance in cold temperatures (as compared to Ni-Cad, Silver Zinc, and Lithium Ion batteries with significant electrolyte that can leak)
  • No maintenance or complex lab equipment required for conditioning or safety
  • No electrolyte leakage
  • Immune to vibration and shock with proper constraints
