Battery Support Units

A stable voltage supply is one of the most critical requirements for successful ECU reprogramming and flashing. Without it, a drop in power mid-procedure can cause incomplete programming, ECU errors or permanent module damage. Our battery support units are built to eliminate that risk — delivering consistent, regulated current throughout every stage of the programming process, exactly as vehicle manufacturers require.

From 150-amp professional power supplies to compact workshop units, each device in this collection offers adjustable voltage output, multiple operating modes and comprehensive safety protection as standard. Compatible with all battery types including Wet, AGM, GEL and Lithium — suitable for modern passenger cars, light commercial vehicles and emerging EV platforms.

  • Professional-grade output — sustained amperage for demanding ECU programming sessions
  • Adjustable voltage — precise control to meet manufacturer programming specifications
  • Multiple operating modes — Programming, Charging and Showroom modes for full workshop flexibility
  • Universal battery compatibility — Wet, AGM, GEL and Lithium supported
  • Built-in safety protection — overheating, overcurrent, short-circuit and overcharge safeguards

All units are supplied with full UK warranty coverage and support from our UK-based team at Dunns Automotive.
