Product Details

The Revolution Power 12v 100Ah Ultra Slim Lithium Battery packs 100Ah of usable LiFePO4 capacity into a slimline 500 x 75 x 260mm profile. Available with an optional mounting bracket (sold separately as RPL12-100USlimMB), it's designed for installs where a full-height battery won't fit — Behind Back seats, under seats, in tight under-floor trays, and purpose-built slim battery enclosures. The IP67-rated case handles exposure to dust and water in demanding environments.

A custom fit for your vehicle — 11 vehicle-specific battery trays available. See fitment options ↓

Key Features

  • 100Ah / 1280Wh usable capacity — full usable rating, not derated — what you see is what you get
  • 100A continuous / 250A peak discharge — handles high-draw loads including inverters, winches, and compressors without voltage sag
  • IP67 rated enclosure — dustproof and jet-water resistant 
  • Slimline form factor (500 x 75 x 260 mm) — designed for space-constrained installs where a standard battery case won't fit
  • 12.5kg — lightweight compared to an equivalent AGM battery
  • M8 terminals — compatible with standard 4WD, caravan, and marine cable terminations
  • Integrated BMS — protects against overcharge, over-discharge, cell imbalance, and temperature extremes — short-circuit response in 200–500µs

Use Cases

Under-Seat & Space-Constrained Installs

The slim profile opens up install locations that a standard 100Ah battery can't fit — under 4WD rear seats, in slim under-floor slide-out trays in caravans, and in motorhomes where floor space is premium. Despite the reduced footprint, it delivers full 100Ah usable capacity with no compromise on cycle life or BMS protection.

Caravan & Motorhome Secondary Bank

Where the main battery bank is a larger unit, the Ultra Slim works well as a secondary bank for specific loads — a dedicated 12V fridge circuit, a secondary lighting run, or a backup system for communications equipment. The mounting bracket option (RPL12-100USlimMB) allows secure vertical or horizontal installation.

Marine Auxiliary Power

In smaller vessel applications where every centimetre of storage space counts, the slimline design allows fitment in lockers, under-seat compartments, and alongside existing marine electrical systems without the depth penalty of a standard battery.
