This makes it one of the best 200Ah lithium iron phosphate batteries in Australia, built with safety and durability in mind.
Parallel and Series Capable
Want more battery capacity? No worries, you can connect up to six of these 200Ah slimline batteries in parallel or series. This is especially useful for off-grid camping or home backup applications where you might need a portable power source for an extended period.
Fast Charging
If you need to charge the battery, there’s no need to wait for long hours anymore! This LiFePO4 Battery 12V 200Ah boasts a fast-charging feature, perfect for adventurers who always need dependable lithium camping batteries on the go.
IMPORTANT: While our LiFePO4 batteries are top-notch & can be wired with other batteries of their kind, it is not advisable to connect any LiFePO4 batteries in parallel or series. This poses several risks and should only be done in emergency situations. If you must wire batteries together, make sure you are familiar with the correct procedure or seek help from a professional if needed.
Suggestions From the Outbax Team
- Batteries connected in series should have the same amp-hour rating, while batteries in a parallel bank should have the same voltage rating.
- As much as possible, only connect batteries in series or parallel during emergency situations.
- 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.

How do I maintain the life cycle of battery?
How do I maintain the life cycle of battery?
1. Lithium batteries that have not been used for a long time should be stored in a cool and dry place. It's best to store them in a semi-electric state. Storage without any power will also damage the battery. Check the battery every 3 months to see if it needs to be recharged.
2. Lithium batteries should be charged while they are in use, but it should be noted that lithium batteries cannot be over-discharged, which will cause irreversible capacity loss. Don't wait to charge the battery until there is no power at all. The best time to charge is when the power state of the battery is less than 10%.
3. Do not mix the lithium battery with metal objects to avoid metal objects touching the positive and negative poles of the battery. This could result in short circuiting, damage to the battery and even cause danger.
4. Use a regular compatible lithium battery charger to charge the battery. Do not use a charger with inferior quality or other types of lead-acid battery chargers to charge the lithium battery.

What is a slimline battery?
What is a slimline battery?
It is a deep-cycle lithium battery (LiFePO4) engineered with a significantly thinner profile compared to standard batteries. It utilises high-quality prismatic cells stacked in an ultra-compact casing to maximise energy density while minimising thickness. The result is a powerful energy storage solution that can fit into spaces where standard batteries simply cannot, such as behind seats, in narrow compartments, or under false floors.
Are the slimline batteries good?
Are the slimline batteries good?
Yes, the low-profile battery does not compromise power, safety, or longevity. In fact, the VoltX 12v slimline batteries feature:
1. Premium Grade-A Prismatic Cells: Ensures stable, high-performance power delivery.
2. Advanced Built-in BMS: Provides crucial protection against overcharge, over-discharge, and short circuits.
3. LiFePO4 Chemistry: Offers superior safety, long-term durability, and an impressive cycle life of over 4000 cycles.
4. They offer all the advantages of lithium with the added benefit of flexible, space-saving installation.
Is this the best 200Ah lithium battery in Australia for off-grid use?
Is this the best 200Ah lithium battery in Australia for off-grid use?

How long does the 200 Ah lithium battery last?
How long does the 200 Ah lithium battery last?
The VoltX 200Ah compact battery is a long-term investment. Based on its LiFePO4 chemistry and prismatic cell construction, it boasts an expected life of over 4000 charge cycles. This translates to a potential service life of 20 years or more, vastly outlasting traditional lead-acid batteries and providing true long-term value for your off-grid setup.
Is the slimline lithium battery better for caravans and 4WDs?
Is the slimline lithium battery better for caravans and 4WDs?
Yes, the slimline design is a game-changer for mobile applications like caravans and 4WDs because it solves the biggest challenge: limited space. It allows the battery to be stowed in otherwise unusable areas, such as behind the back seat of a dual-cab ute, mounted on the side of a canopy, or placed neatly within a narrow cupboard in a caravan. In addition, by fitting into non-traditional locations, the reduced battery weight is crucial for vehicle handling, safety, and fuel efficiency.
How long does the VoltX 200Ah slimline battery charge take?
How long does the VoltX 200Ah slimline battery charge take?
The charging time depends on the current supplied by your charger. Our recommended standard charge is 100A, which takes about 2 hours (200Ah/100A) from empty (0%) to full (100%). And the advanced BMS supports a maximum charging current of 200A, which achieves a full recharge in as little as 1.33 hours (200Ah/200A).
