Model Li3326QC/ 400 Amp Set

Mobile 26V Lithium Aircraft START PAC®
Mobile 24-28V 400A Aircraft Power Supply

The engineers at START PAC® specifically designed the new Li2700QC as an airplane starting unit for aircraft with voltage protection relays that are set lower than most aircraft, meaning that they cannot accept more than 29.5 volts from an external starting source. These aircraft include but are not limited to the Agusta Westland AW139, Sikorsky S-76, Eclipse 500 and both the Phenom 100 and Phenom 300.

This unit is designed for engine starting only.

  • Not to be used as an aircraft battery charger.
  • Do not charge in flight.

The all new START PAC® Model Li2700 QC Twin Pac utilizes the latest technology in Lithium batteries; these batteries provide the same power as the lead-acid type, but are 42% lighter and 32% smaller. In addition, lithium batteries have two other major advantages:

  1. Twice the battery life of lead-acid batteries
  2. No sulfation problems (can be left in a discharged state without causing damage)

NOTE: When storing the START PAC® for more than 30 days, remove the battery box from the charging unit and keep separately.

PLEASE NOTE: Lithium ion batteries can be damaged by deep discharges. Do not run the batteries down below 23 volts; a spike during a start is okay. Voltages below 22 will begin to damage the batteries and at 20 volts, the batteries will be damaged beyond repair.

Mobile 24-28V 400A Aircraft Power Supply

When plugged into 220Volt single-phase AC power, START PAC® Model 53400 is a 28.5 Volt continuous DC power supply. This unit will deliver full 400 Amp DC output, but it won’t provide enough current for engine starting. This unit therefore, has been specifically designed for maintenance and to power up various functions. such as inverters, avionics, GPS, and air conditioning. This unit requires 220 Volt single phase power to operate.

Remember, this unit is NOT designed for engine starting or battery charging.

Please Note
