Power is the quiet backbone of a good 4WD touring setup. A rooftop tent makes sleeping easier, an awning makes camp more comfortable and a fridge keeps food cold, but none of it works properly without reliable 12V power. The ATEMPOWER 100Ah 12V Slimline Lithium Battery is aimed at drivers who want a compact LiFePO4 battery that can fit into tighter spaces behind seats, in canopies or inside touring storage systems.
This review looks at the current VicOffroad listing, key specs and whether this battery makes sense for 4WD camping.

Quick Verdict
The ATEMPOWER 100Ah slimline lithium battery is a good fit for 4×4 owners who want useful capacity without giving up too much cargo space. Its 61 mm slimline case is the main selling point. That shape can be easier to install behind seats, against canopy walls or in storage areas where a normal battery box is too bulky.
It is especially relevant if you plan to run a camping fridge, lights, device charging and small 12V accessories. For heavier inverter loads, you need to check the full system design carefully.

Why Slimline Matters
Many 4WD battery setups run into the same problem: space. A traditional deep-cycle battery box can take up too much room in the back of a wagon or ute. A slimline battery gives you more mounting options.
The ATEMPOWER model lists a 61 mm thickness, which makes it suitable for tight spaces where a standard battery may not fit neatly. That can be useful behind rear seats, along a canopy wall or inside custom touring storage.
For a daily-driven 4×4, this matters because every bit of cargo space counts. A slim battery can leave more room for drawers, fridge slides, recovery gear, water storage and camping equipment.
What Can A 100Ah Lithium Battery Run?
A 100Ah lithium battery is a common size for weekend touring. It can typically support a 12V fridge, camp lighting, phone charging, a small water pump and other low-to-moderate draw accessories, assuming the system is set up properly.
The exact runtime depends on the fridge draw, ambient temperature, wiring, battery management system, charging source and how deeply the battery is discharged. A fridge like the San Hima 75L dual-zone model is a natural companion product, but it should be paired with correct wiring and charging.
If you plan to run inverters, microwaves or high-draw appliances, do not guess. Get the complete power setup designed properly with suitable fuses, cable size, charging and ventilation.
What We Like
The first positive is the combination of 100Ah capacity and slimline packaging. That gives touring drivers useful energy storage without the bulk of older AGM battery setups.
The second advantage is weight. The listing highlights a 13.8 kg design, which is much lighter than many older lead-acid batteries with similar usable capacity. Less weight is always welcome in a 4WD build.
The battery also lists a smart BMS to help prevent overcharging and over-discharging. That is important because lithium systems should not be treated like old-school batteries. Good battery management helps protect the cells and the rest of the system.
The output figures are strong for a compact battery. A listed 150A continuous discharge and 250A pulse discharge gives useful flexibility, although any high-draw setup still needs correct system design.
What To Check Before Buying
First, check charging compatibility. A lithium battery should be charged with lithium-compatible equipment. If your current DC-DC charger or solar regulator is set up for AGM or lead-acid only, confirm whether it supports LiFePO4 before connecting anything.
Second, check cable size, fusing and mounting. The battery may be compact, but it still needs to be secured properly. Loose batteries and poor wiring are not acceptable in a touring vehicle.
Third, check whether 100Ah is enough. For a weekend fridge and lights setup, it often is. For long stationary camps, high fridge loads, inverters or multiple accessories, you may need solar, a second battery or more capacity.
Best Use Cases
This battery suits:
- 4WD wagons with limited cargo space.
- Ute canopy builds where a slim wall-mounted battery is useful.
- Touring setups running a fridge and lights.
- Camper trailers needing a compact LiFePO4 battery.
- Drivers replacing older AGM batteries to save weight and improve usable capacity.
It may not be the best choice if you need a simple plug-and-play power box. This is a battery for a proper 12V setup, not a complete portable power station by itself.
Is It Worth It?
Yes, if the slimline shape solves a real fitment problem in your vehicle. The ATEMPOWER 100Ah battery has a good combination of capacity, compact packaging, output and weight for 4WD touring use.
If you are building a system around a fridge freezer, camp lighting and touring accessories, this is exactly the kind of battery that makes the setup more practical. If you only need to charge phones on short trips, it is probably more battery than you need.

FAQ
Is 100Ah enough for a camping fridge?
For many weekend setups, yes. Runtime depends on fridge size, ambient temperature, battery condition, wiring and whether you have solar or DC-DC charging.
Do I need a lithium-compatible charger?
Yes. Check that your DC-DC charger, mains charger or solar regulator supports LiFePO4 battery charging.
Can it fit behind seats?
The supplier highlights a 61 mm slimline design, which may suit behind-seat or canopy-wall mounting. Measure your own vehicle before ordering.
Is this a complete power station?
No. It is a battery. You may still need charging equipment, fuses, cable, mounting, outlets and possibly a battery monitor depending on your setup.
Final Verdict
The ATEMPOWER 100Ah Slimline Lithium Battery is a sensible 4WD touring product because it supports the rest of the camp setup. It pairs naturally with a fridge freezer, awning, rooftop tent and lighting system.
For drivers who want a tidier 12V setup without giving away too much storage room, the slimline shape is the main reason to put it on the shortlist.
