Clean Quiet Safe Power

The perfect small utility battery for your outdoor actvities!

The super handy travel case has a comfortable handle and is made of stainless steel for easy use and assured durability for your outdoor activities.


Portability and Ease Of Use

Weighing only 10.8kg makes it very easy to take anywhere and allow endless uses!

The power density and deep discharge capability of the battery makes it comparable to a 200 Amp hour normal lead acid battery that will likely weigh 60kg+! The lead acid battery is also likely to be much larger – in the range of 513 mm x 274 mm x 242 mm, making the Voyager Max a much lighter, more powerful and more compact option.

LiFePo4 Advantages

The Lithium Iron Phosphate (LiFePo4) battery chemistry is FAR safer than the more usual Lithium Ion batteries. It means that the Voyager Max 12V100 cannot catch fire even when under severe duress, overheating or shorting out. Plus there is no acid to spill or fumes to breath – a safe sealed system ideal for demanding environments.

LiFePo4 also has far more longevity than Lithium Ion, with the LiFePo4 batteries having a 3,000 cycle life compared to the more usual 600-800 for Lithium Ion and only a few dozen for a lead acid battery if you regularly discharge it beyond 50%!

Compared to many other marine batteries, the connectivity options on the Voyager Max series are impressive:

  • 8mm terminals
  • 20A Waterproof plug with stable 12V output for sensitive fishfinders and depth gauges
  • USB 3.0 x 2
  • Charging socket
  • Bluetooth Battery Management System (BMS)

Compared to a “dumb” lead acid battery, there is no comparison!


The performance of the LiFePo4 battery completely overshadows lead acid with a much flatter voltage discharge. This means that the Voyager Max will continue putting out full voltage until it is completely discharged, giving you more power for longer, taking you further and faster.

The higher price of a LiFePo4 battery is more than offset by its very long life, deeper discharge cycle, smaller size, safe chemistry and vast connectivity abilities.

Assuming you fully cycle it 30 times a year this could be the last battery you ever need to buy.

Truly a battery for life!

    • using the stable 12V output
  • Depth gauge
    • using the stable 12V output
  • Camping
    • Keep all of your electrical gadgets charged up
    • Run your camping lights
    • Night camping
  • With an inverter (not supplied) use as a portable power station
    • Charge up laptops and other mains powered devices – why work from home when you can work from your boat or van?
  • Charge from solar panels (not supplied)
  • Use on site for power tools
    • Charge your portable tools
    • With a suitable inverter (not supplied) you can run many mains power tools (check maximum power draw especially when the tool starts up)

Lithium Iron Phosphate Battery Benefits

  • Contains a single large LiFePo4 lithium battery for a stronger more stable current output
  • LiFePo4 batteries have
    • much higher safety – no “thermal runaway” so will not catch fire if overheated, short circuited or even pierced with 6 inch nail
    • longer service life – 3,000 cycle life
    • wider operating temperature range

When compared to the more usual Lithium Ion batteries and traditional lead acid batteries, the comparison is scarcely worthwhile!
