The Li3326-105 GPU is designed to provide both continuous power and starting power to the aircraft while on the ground.

It features a 26VDC battery bank to provide superior starting power to the aircraft, while it also features a rectifier that will convert AC input voltage (220 single phase) to 28.8VDC to power avionics and other aircraft systems such as air conditioning.

The Li3326 has a large battery capacity (70AH) with a 105-amp power supply when connected to 220 Volt AC. When connected to AC power, the depleted batteries of this ground power unit can be charged in a matter of hours with the built-in portable power supply/battery charger.


  • 78 Amp Hours at 10 hour rate
  • 26 Volt DC – 28 Volts at rest
  • Sealed cells non- hazardous
  • Valve regulated high amperage output lead acid
  • 3200 Peak Amps

Power Supply/Charger

  • Multi- unit 105 Amp DC continuous output
  • 28 – 28.5 Volt output is 105 amp load
  • Battery recharge time from fully discharged – 2 hours
  • AC Input – 110 Volt or 220 Volts (only 1)


  • 200 amps maximum DC load

  • NOTE- When using more than 150 continuous amps, the batteries will make up the difference until they become depleted. On most aircraft, a low voltage relay will drop the GPU offline when the voltage drops below a preset level. Once the GPU is dropped off, its voltage will rise and will be accepted again by the aircraft, then will immediately drop off again. This oscillation can cause damage to aircraft components.

The following dimensions apply to each of the 3300s:
Weight: 130 lbs
L 38″ x W 21″ x H 20″/L 96.52cm x W 53.34cm x H 50.8cm; Handle Height 48″/121.92cm.

The GPU is rated at 3200 peak starting amps and a continuous 105 Amp DC output when connected to a 110 Volt or 220 Volt AC source.The GPU is rated at 3200 peak starting amps and a continuous 50 Amp DC output when connected to a 110 Volt or 220 Volt AC source.

The Li3326 weighs 130 lbs and is pulled by hand or tug. Locking the handle in an upright position sets the GPU brake.

Always recharge the GPU until the green charger light appears. Once charged, it is not necessary to leave the unit turned on. If a heater is installed, leave the unit plugged in.

Avoid discharging the batteries completely as damage can result.

NOTE- PLEASE USE #12 or Larger AC EXTENSION CORD There are approximately thirty 110 volt and thirty 220 volt NEMA plugs in use. Also, customers have various receptacle at their hangars and MRO facilities and may require specific AC cord length to meet their requirements. Due to these facts, we do not automatically provide AC power cords. If you provide the NEMA plug number and specify the AC power cord length you require we will build a cord to be shipped with your unit for a small fee.
