The Unit

Big power in a small footprint

The JAM Lite is our most versatile unit — compact enough to be positioned by hand truck or pallet truck, yet powerful enough to run a production set, a welfare block or a small construction compound for a full working day without a recharge.

Where access is tight, noise restrictions apply, or you simply don’t need the scale of the Pro, the Lite delivers everything you need without excess. It shares the same LiFePO₄ chemistry, the same smart BMS, and the same 24/7 UK support as the rest of the JAM range.

Where it excels

Backstage and production areas where access is restricted to smaller equipment

Urban construction sites with strict noise and emissions controls

Film and TV locations inside buildings or heritage sites

Short-duration events and one-day hires where a larger unit is overkill

Emergency standby power for telecoms cabinets and remote infrastructure

Paired units for flexible capacity scaling — run two Lites in parallel for 100kWh

Pallet-truck Moveable

At 480kg the Lite can be repositioned on site with a standard pallet truck. No telehandler or crane required.

Zero Thermal Runaway

LiFePO₄ chemistry — the same inherently stable cells used across the full JAM range. Safe indoors, safe everywhere.

Parallel Ready

Stack multiple Lite units in parallel for up to 100kWh. Flexible capacity without committing to a larger unit hire.

Smart BMS Included

Full battery management with real-time SOC, temperature monitoring and remote telemetry as standard.

24/7 UK Support

Every hire includes round-the-clock support from our UK-based team. Same commitment regardless of unit size.

Same-Day Delivery

The Lite’s compact size means it can ship on a standard van. Same-day delivery available across most of the UK.

Ideal For

Where the Lite works hardest

Events & Festivals

Silent, compact and repositionable. Power production areas, bars, catering units and backstage infrastructure without running cable from a remote generator.

Film & TV

The go-to unit for location power inside buildings, on heritage sites, or anywhere a larger unit can’t access. Zero noise means zero sound bleed.

Urban Construction

Meets the tightest NRMM and noise restrictions. Power tools, welfare and lighting in city-centre or residential sites without permits or complaints.

Telecoms

Compact standby power for remote mast sites and exchange infrastructure. 4G telemetry keeps your team informed without site visits.

Emergency Services

Van-deliverable and rapidly deployable. Power command units, field communications and lighting at incident scenes with zero emissions.
