Unmatched Performance for Fridges and Appliances

A 100Ah lithium pack can keep a 12V fridge and other small appliances running for hours, perfect for weekends away or emergency use.


LiFePO4 vs. Lead-Acid: A Clear Comparison

LiFePO4 batteries last up to 10 times longer, hold charge more efficiently, and provide more usable power than traditional lead-acid units.


Key Features of a High-Performance 100Ah Power Pack

Built-in Battery Management System (BMS)

A smart BMS protects your battery from overcharging, deep discharging, and overheating, ensuring safe and reliable use.


Versatile Charging and Output Ports

Portable Lithium Battery Pack 100Ah FAQs

What is a 100Ah portable lithium battery pack and what can it run?

A 100Ah lithium battery pack stores around 1,000-1,280Wh of usable energy depending on voltage and chemistry. That's enough to run a 12V fridge for 24-48 hours, charge phones and laptops multiple times, power lights and a CPAP overnight, or run a small inverter for power tools on site. They're a step up from traditional lead-acid batteries - lighter, faster to charge, and they can be discharged much deeper without damage.

How much does a 100Ah lithium battery pack cost in Australia?

Prices vary depending on the brand and features, but in Australia you're generally looking at anywhere from $400 to over $1,500 for a quality 100Ah lithium pack. Budget units cut corners on the battery management system (BMS) and build quality. True Gear stocks mid-to-premium options from trusted brands that are properly spec'd for Australian conditions - heat, dust, and hard use.

What brands of 100Ah portable lithium battery packs does True Gear stock?

True Gear stocks portable lithium battery packs from leading brands including Bluetti, EcoFlow, and others. These brands use LiFePO4 (lithium iron phosphate) chemistry, which is safer and longer-lasting than standard lithium-ion - typically rated for 2,000-3,500+ charge cycles. Check the collection for current stock and pricing.

What should I look for when buying a 100Ah lithium battery pack in Australia?

The main things to check are battery chemistry (LiFePO4 is the gold standard for longevity and safety), the quality of the built-in BMS (battery management system), IP rating if you're using it outdoors, output options (Anderson, 12V cigarette, USB-A, USB-C), and whether it can be solar charged. Also check operating temperature range - cheaper units struggle in Australian summer heat. Warranty length and where you can get it serviced in Australia matters too.

Can I use a 100Ah lithium battery pack to run a 12V fridge while camping or in my 4WD?

Absolutely - that's one of the most common uses. A 100Ah pack will run a quality 40-60L 12V compressor fridge for roughly 24-48 hours depending on ambient temperature and how often you open it. Pair it with a solar panel and you can run the fridge indefinitely off-grid. It's a solid setup for a weekend trip or a longer 4WD adventure.
