Packs & Modules — Residential, LEV, Marine, Telecom

Why these exist

The pack line came first.

Our manufacturing base has been building lithium packs since 2014, starting with waterproof and marine packs. The C&I cabinets came later — the sealing and thermal discipline came from here, not the other way round.

Same gates as the large systems: cells matched before assembly, 100 % hipot, ageing at 1 C with continuous monitoring, and a unique serial on every pack traceable to its cell batch.

Cell matching. Voltage spread ≤ 5 mV, internal resistance ≤ 0.2 mΩ, capacity measured rather than declared.
Sealing. IP62 to IP68 depending on family — the IP68 know-how dates from the 2017 waterproof programme.
Traceability. Every pack serial-numbered; the production record travels with it.

LFP prismatic cells staged for pack assembly, terminals protected

Six families

One line, six product families.

Figures are indicative for the standard build and confirmed in the technical annex for your configuration. Anything outside the table is quoted, not assumed.

Family	Formats	Range	Cycles	Sealing	Typical duty
Residential storage	Stacked tower · wall-mount · all-in-one	5–40 kWh, parallel to 60 kWh	> 6,000	IP20–IP55	PV self-consumption and backup; integrated heating film for −20 °C sites
Lead-acid replacement	12.8 / 24 / 48 V bloc	100 / 200 / 300 Ah	3,000+	IP62	1:1 drop-in at roughly half the weight; UPS, telecom, street lighting, CCTV
Light electric vehicle & swap	Swap pack · rack pack	60 V 50 Ah, 100 A max discharge	> 2,000	IP65	Two- and three-wheel fleets, battery-swap networks, last-mile delivery
Marine & electric raft	Sealed pack with BMS and telemetry	76.8 V 11.5 kWh	> 2,000	IP67	Electric raft and small craft; GPS and 4G remote monitoring integrated
Portable power	Portable inverter unit	1 kWh, 2 kW output	> 2,000	IP20	Outdoor, emergency and off-grid use; cylindrical LFP cells
Telecom & data centre	19-inch rack module	51.2 V 100 / 150 / 220 / 325 Ah, 15 in parallel	> 6,000	IP20	Base-station and data-centre standby, UPS, cold-start duty

On the floor

Photographs from our own line.

No stock images. Every photograph on this site was taken on the floor of the facility that builds the packs.

Pack assembly line with units on individual pallets — Assembly — each unit on its own pallet, serial-labelled before it leaves the bay.

Ageing room with charge and discharge racks — Ageing — 1 C cycling with cell-level voltage and temperature logged against the serial.

Export packing with UN 38.3 Class 9 labelling — Despatch — UN 38.3 Class 9 labelling and sea-worthy packing as standard.

OEM / ODM

Built to your drawing, not only to catalogue.

12 V to 1,000 V class platforms, 4 Ah cells to MWh containers, IP20 to IP68. Custom BMS parameters, enclosure, connector, label and packaging.

Your brand on the outside, our serial inside — so a warranty claim two years later is still a database lookup.

What you specify

Voltage window, capacity, continuous and peak current, duty cycle, enclosure, connector, communication protocol.

What we return

A datasheet, a dimensioned drawing and a sample plan. No sample before the drawing is agreed.

What ships with it

UN 38.3 summary, factory test report against the serial, certificate of conformity, manual.

Tell us the duty cycle. We will send the datasheet.

Voltage window, energy, power and C-rate, duty profile, installation environment, destination country. That is enough for a first proposal.
