When building out a modern 4WD canopy, dual-cab ute tub, camper trailer, or custom drawer setup, space is always at a premium. Upgrading to a lithium battery system is the best way to double your usable off-grid energy, but standard battery casings often take up valuable storage room or force awkward mounting choices.
To solve space restrictions on the track, DC Direct is proud to introduce the Invicta 100Ah Compact Lithium Battery (LiFePO4). Built using trusted Invicta Compact casing technology, this battery packs 100% usable lithium energy into a significantly smaller footprint than standard 100Ah batteries.
Don't compromise your storage space or overload your vehicle payload. The Invicta 100Ah Compact Lithium Battery gives you big off-grid power in an ultra-slim footprint.

Why Space-Saving Battery Footprints Matter in Modern Rigs
Upgrading your 12V system isn't just about total Amp-Hours; it's about layout flexibility and keeping your Gross Vehicle Mass (GVM) under control.
Traditional lead-acid or AGM batteries are notoriously heavy (often weighing 30kg+ for a 100Ah unit) and bulky. Furthermore, AGM batteries can only safely utilize 50% of their rated capacity without suffering permanent cell damage.
The Invicta 100Ah Compact Lithium Battery delivers full Lithium Iron Phosphate (LiFePO4) performance in a casing designed specifically to fit tight spaces where standard batteries simply won't go:
-
Under-Seat Mounts: Fits neatly beneath passenger seats in dual-cab 4WDs.
-
Canopy Drawer Wings: Fits inside narrow side compartments and dead space behind drawer systems.
-
Ute Tub Setups: Mounts flush against tub walls without hogging cargo space.
Pairing this battery with our Invicta IP68 Heavy-Duty DC–DC Chargers — 25A or 40A — creates a rapid-charging, space-efficient dual battery system that recovers fast while driving.

Frequently Asked Questions
How does a compact lithium battery save space compared to a standard lithium battery?
Standard lithium batteries are often built into traditional lead-acid casing sizes (like Group 24 or Group 31 N70 sizes). The Invicta 100Ah Compact utilizes high-density LiFePO4 cells packed into an optimized chassis, reducing outer dimensions while maintaining a full 100Ah usable capacity.
Can I charge the Invicta Compact Lithium Battery directly from my alternator?
No, you should always use a dedicated DC–DC charger when charging a LiFePO4 battery from a vehicle's alternator. Modern vehicles require regulated voltage and current multi-stage charging profiles to prevent alternator overheating and ensure full lithium battery saturation. Check out our 25A Invicta DC–DC Charger or 40A Invicta DC–DC Charger for compatible options.
Does the built-in Battery Management System (BMS) protect against low temperatures?
Yes. The integrated Smart BMS continuously monitors cell voltages, currents, and internal temperatures. It prevents charging or discharging if conditions exceed safe operating thresholds, ensuring long cycle life and safety off-road.
How do I monitor the state of charge on the compact battery?
The battery features built-in Bluetooth connectivity. Simply download the monitoring app on your iOS or Android smartphone to view live battery status, remaining capacity percentage, current draw, voltage, and cell balance in real-time.
Can I connect multiple Invicta 100Ah Compact batteries together?
Yes, depending on your setup requirements. You can connect compatible units in parallel to increase total Amp-Hour capacity (e.g., 200Ah or 300Ah total) or in series for 24V/36V systems, provided you follow correct balancing procedures.
