GYSFlash Pro Connected

GYSFLASH 100.12 HF (5 m Cables)

These latest models represent the most powerful BSUs in the GYSFLASH PRO range. Will compensate the energy requirement during diagnostics or in the showroom and they are fully connected. This makes it possible to create or upload customised lead-acid and lithium charge curves via the USB port. They also create a file of charging data for analysing on a computer or for printing. Traceability is another key feature.


4 Operating Modes

  • Charging: for 12 V Lead or Lithium (LFP) batteries from 5 to 1500 Ah.
  • Diagnostics: supports up to 120 A for 12 V batteries in vehicles in the diagnostic phase, in maintenance workshops.
  • Showroom: provides power compensation when using the electrical accessories of a demonstration vehicle. It also manages the optimal charging of the battery.
  • Tester: Allows you to check the battery voltage, evaluate the starting system (starter + battery) and the condition of the vehicle’s alternator


  • Add, delete or modify charging modes and profiles via USB.
  • Import predefined configuration files adapted to the load trades.
  • Retrieve the charging history and data on a USB stick and use them on a spreadsheet.
  • Connect additional modules (printer, barcode reader, etc.) via its dedicated module socket (SMC: Smart Module Connector).


  • Extends the life and performance of Lead (gel, AGM, liquid, calcium, etc.) and Lithium (LFP) batteries.
  • Specific charging curve in 8 steps (lead battery) or 9 steps (lithium-iron phosphate battery) without supervision.
  • Recovers deeply discharged batteries >2 V (automatic SOS Recovery).


  • FV Flexible Voltage, the charger operates with a supply voltage between 85 and 265 V.
  • «Auto-Detect» function automatically starts a charge when a battery is connected to the charger.
  • «Auto-Restart» function in the event of a power failure with memory of the settings.
  • Cable inspection and calibration
  • Locking, avoids the risk of improper handling, ideal for garages and exhibition halls.
  • Up to 12 charging profiles available, including the Easy profile for simplified charging suitable for all lead batteries.


  • Protection of the vehicle’s on-board electronics: protection against short circuits, polarity reversal and overcharging. Spark prevention system.
  • Interchangeable fusible which protect against misuse.
  • Temperature sensor to prevent internal electronics overheating.


  • Durable case with shock and vibration absorbing pads.
  • Low height (13 cm) for the loader to pass under a vehicle.
