Product Details

Since its launch in 2018, VoltX batteries have consistently grown to now become Australia's favourite Lithium batteries. With over 20,000 happy customers and growing, we are already a market leader in the recreational battery space.

Efficient and Safe

The VoltX 12V 100Ah lithium battery is composed of brand-new A-grade prismatic cells, making them super reliable and energy-dense.

Its super-effective integrated battery management system (BMS) keeps the battery to safe operating limits – disconnecting it to prevent damage from temperatures/voltage changes, overload and short-circuits

The most suitable battery for camping

This best-selling LiFePO4 battery is compact and perfect for campsites and RVs. Designed to last for up to 2,000 cycles, this is every avid camper's dream power pack.

Reliable and Durable

Our LiFEPO4 portable batteries provide 100% capacity. And unlike regular lithium batteries, the user can use 100% of its capacity without degradation. The cells in the batteries are encased in an aluminium casing for durability and offer a solid working temperature range, making them a reliable source of power even in harsh outdoor conditions, rough terrains, and extreme weather.

Tested for performance and to meet the most stringent international standards, VoltX batteries are perfect for running gadgets, fridges, washers, and wireless tools smoothly.

IMPORTANT: While our LiFePO4 batteries are top-notch, it is not advisable to connect any LiFePO4 batteries in parallel or series.

What Are the Risks of Connecting Lithium Batteries in Series or Parallel?

  • Series connection of any battery is generally not recommended. This can cause "barrel effect" which results in the weakest cells dominating the battery, permanently damaging and reducing its lifespan.
  • Anything more than this can also impact your battery's overall health and performance.
  • Batteries may be damaged due to excessive cycling or overcharging.

Suggestions From the Outbax Team

  • It's better to go for batteries with higher voltage when running high-power electrical appliances instead of wiring two battery packs together.
  • We have available batteries with larger discharge parameters for fast charge/discharge requirements.
  • Our batteries are also available in 200Ah and 300Ah for larger capacity demands.

Suitable for:

  • Televisions
  • Laptops / Computers
  • Small Fridges
  • Power Tools
  • Gaming consoles
  • Water pumps

*Depends on the size of the appliance

Should have done this ages ago
Love our VoltX Lithium batteries! Bought 2 x 100Ah which we use to run our fridges. So impressed with their endurance that I've just bought another 2 for the caravan!

Very Efficient Battery
This is the first lithium battery I've purchased. So far so good, I ran my 39 litre Engel off the battery for 30 hours and only dropped 1 volt. Please with purchase.
