How it works
Thin-plate lead-acid, built to deliver amps in seconds.
A starter unit's job is narrow but demanding: hold thousands of amps in reserve for months, then deliver them the instant a crew needs an engine turning. The battery chemistry and the charger matter more than anything else in the box.
Two outputs, one battery bank.
A 3-stage charger keeps the sealed lead-acid bank topped from any 90–260VAC hangar or generator supply. A mode switch selects continuous output — a steady 28.5V DC for avionics, maintenance, and diagnostics — or start mode, where the bank discharges thousands of amps into the aircraft's starter or APU in a matter of seconds.
Digital current and voltage meters, over-voltage and over-temperature protection, and a push-to-test battery check are standard across the range — so a ground crew can read the unit's state without opening a laptop.
In use
From flat case to engine start.
Connect to the aircraft
The output lead's rubber aircraft plug connects directly to the aircraft's ground power receptacle.
Select continuous or start
A mode switch routes the battery bank to steady 28.5V DC output, or to the high-current start contactor.
Power avionics, or start the engine
Continuous mode runs avionics and maintenance work; start mode delivers up to 5,000A to turn the APU or engine.
Recharge from flat
The 3-stage charger returns a fully discharged bank to ready in as little as 30 minutes once mains power is applied.
