Product Code: PIRDBAOC
The Piranha AOC makes using a DC/DC isolator for dual battery management a thing of the past, for many vehicles. Using the Piranha AOC in conjunction with a Piranha Dual Battery manager,DBE140S or DBE180-SX, allows you to use the full available output of the alternator to recharge your auxiliary battery / batteries while the vehicle is in use. It will also charge your main battery if you have changed to a high technology AGM style battery.

The AOC is designed for use with many of today’s current 4x4 vehicles with VARIABLE RATE ALTERNATORS  which up to now used a DC/DC style isolator,  which is a high cost solution and limited to the output of the DC/DC. Most times slowing down the recharge time.

For such a small device it  packs a very capable electronics package to provide a very useful .4Volt -.5Volt increase  in your charge rate while still affording all the protection of a fused circuit as required by the manufacturer.


There are similar looking devices available that do not offer the fused protection of the Piranha AOC and are only one way .  Research and engineering have combined to provide this low cost, high technology solution, suitable for today’s vehicles.

Suitable for vehicles:

  • Toyota Prado 120 series
  • Toyota Prado 150 series
  • Toyota Hilux 2005 onwards
  • Landcruiser 200 series
  • Landcruiser 79 series
  • Landcruiser with V8 Diesel
