Invicta Lithium Compact Range — 12V LiFePO4 Batteries for Deep Cycle Applications
When space is tight but power demands aren’t, the Invicta Lithium Compact range delivers. Built as a replacement for similarly sized lead-acid batteries, it packs full Lithium Iron Phosphate (LiFePO4) performance into a smaller footprint than you’d expect for the capacity on offer — making it the smart choice for deep cycle applications where every centimetre counts.
Available in 100Ah, 200Ah and 325Ah 12V configurations, every battery in the range is backed by an integrated Battery Management System (BMS), Bluetooth connectivity, and the reliability Invicta Lithium customers expect.
Features & Benefits
- A genuinely compact footprint. Most 12V lithium batteries are still built to legacy lead acid case sizes (Group 31, 4D/6D, 8D). The Compact range breaks that mould, engineered a full case size down from the industry-standard footprint for each equivalent capacity — freeing up space in your caravan, boat, 4WD canopy, or off-grid enclosure.
- 15%-41% Less Volume Compared to Other Lithium. When you have a tight space but need the same power
- 5-Year Warranty. Built with Invicta quality and attention to detail that you can rely on
- Up to 8x the cycle life. Rated for more than 2,000 cycles at 100% depth of discharge, the Compact range delivers up to eight times the working life of a comparable SLA battery — fewer replacements and a lower total cost of ownership.
- Less than half the weight of lead-acid. High energy density means significantly less dead weight for the same, or better, usable capacity — whichever application you’re loading it into.
- Integrated BMS for total peace of mind. Every battery includes a fully integrated BMS, protecting against overcharge, over-discharge, excessive temperature, and short circuit — safety built in at the cell level.
- Bluetooth monitoring, right in your pocket. Pair with the free INVICTA App (iOS and Android) to monitor state of charge, voltage, and battery health in real time — no multimeter required.
- Flat discharge curve, fast recharge. More usable capacity delivered at stable voltage for longer run time, plus faster recharge than lead acid so you spend less time waiting.
- Extremely low self-discharge. Ideal for seasonal equipment, storage, and standby power.
How Does It Compare in Size to Other Lithium Batteries?
Most 12V lithium batteries on the market are still built to legacy lead acid case sizes. Here’s how the Compact range measures up against those typical industry-standard footprints, capacity for capacity:
| Capacity | Compact | Standard | Saving |
|---|---|---|---|
| 100Ah | 260×169×215mm | 306×168×216mm | ~15% shorter, ~15% less volume |
| 200Ah | 345×190×245mm | 483×170×241mm | ~29% shorter, ~19% less volume |
| 325Ah | 384×194×248mm | 518×271×222mm | ~26% shorter, ~41% less volume |
In practical terms, that’s the difference between a battery that just fits and one that frees up an entire extra compartment, shelf, or storage bay for gear. It’s also lighter than most equivalent-capacity lithium batteries in a full-size case, since less material means less mass for the same cell chemistry.
LiFePO4: The Safer, Smarter Lithium Chemistry
Not all lithium batteries are created equal. The Compact range uses Lithium Iron Phosphate (LiFePO4) chemistry — widely regarded as the safest and most stable lithium chemistry available, thanks to its high thermal and chemical stability. Combined with cell-level BMS protection, it’s built for safety-first, long-life performance.
