OEM & custom packs
CLN Energy builds lithium iron phosphate packs to a customer's own specification — the voltage the equipment runs at, the energy it needs, the space it has to fit and the protocol it has to speak. Current production spans roughly 12.8V to 720V and from a 1.28 kWh residential pack to a 5.015 MWh containerised system, at a plant with more than 2 GWh of annual capacity.
These are the formats already in production. A custom requirement is usually a variation on one of them — a different capacity, a different enclosure, a different way of reporting — which is faster and cheaper than starting from nothing.
| Format | Typically for | Notes |
|---|---|---|
| Table top and wall mount | Homes, shops, small offices | Behind an inverter or a UPS |
| Ground mount, on castors | Larger homes, clinics, small industry | Where floor space is easier than wall |
| 19-inch rack modules | Telecom cabinets, data centres | RS485 to the site controller |
| Stackable modules | Homes and commercial buildings | Capacity added a module at a time |
| Vehicle packs | L2, L3, L5, loaders, golf carts, MHE | IP-rated, built to the tray and the controller |
| Containerised systems | Grid, utility and industrial projects | Liquid cooled, up to megawatt hours |

Four answers are enough to start, and most buyers have three of them already. The voltage the equipment runs at. The energy or runtime it has to deliver, which is the load multiplied by the hours. The envelope — the tray, the cabinet or the floor space the pack must fit, and the ingress protection the environment demands. And the interface: whether it reports over RS485 or CAN, and what reads it.
From there the sequence is design, sample, validation, then production. Where a certification applies — a vehicle pack, a telecom site — that testing sits between validation and volume, and it is the step worth planning around.
Manufacturing happens at the company's own plant rather than through an importer. That is the practical difference for an OEM buyer: a specification change is a conversation with the people building the pack, and a warranty claim is handled by the company that built it.
The clearest evidence that a custom pack works is one already running somewhere demanding. BSNL has 22,864 CLN packs across its telecom network, in 400Ah and 800Ah module capacities, with a five-year AMC after the warranty period. RailTel runs 180 kWh behind the 100 kW UPS at its Pondicherry command control centre, changed over inside a two-hour window without the centre coming off supply. Southern Railway uses CLN packs for automatic block signalling backup at Chennai — 10 kW SMPS, 14.4 kWh, seven hours at a 2 kW draw.
Each of those is on its own project page with the real configuration, and the plant itself is described on the Noida manufacturing page.
Yes - that is most of what the plant does. A custom pack starts from four things: the voltage the equipment runs at, the energy or runtime it needs, the space and mounting it has to fit, and how it must communicate. From there the pack is designed around lithium iron phosphate cells with a battery management system, assembled and tested at the Noida plant. CLN already builds across a wide range - roughly 12.8V to 720V and from a 1.28 kWh residential pack to a 5.015 MWh containerised system - so a new requirement is usually a variation on something already in production rather than a first of its kind. Send the specification, or the equipment it powers, and the engineering team will come back with a configuration.
It depends on the pack rather than on a company-wide rule, so the honest answer is to ask with the volume in hand. What drives it: whether the design is close to something already built, the cell format the pack needs, whether tooling or a new enclosure is involved, and how the delivery is phased. A pack that is a variation on a current model starts lower than one that needs new mechanicals. Tell us the annual volume and the first order you have in mind and you will get a real answer rather than a policy.
Packs are built and tested to UN 38.3 for transport, IEC 62619 for industrial cell and battery safety, IEC 61000 for electromagnetic compatibility, and UL 1973 and UL 9540A for stationary safety and thermal runaway. The plant is certified to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018. For electric vehicles the company states AIS 156 Phase II Amendment 3 for its EV packs, and T-SEC certification on the telecom range. Which of those apply depends on where your pack is used, and the certifications page sets out what each one actually covers.
Either. The standard build carries a smart battery management system handling protection against over and under voltage, over current, short circuit and temperature, with cell balancing, and it reports over RS485 or CAN so the equipment above it can read state of charge and health. Telecom modules report to the site controller that way, and the e-mobility packs can carry IoT and app monitoring. Where you have your own BMS or your own protocol, that is a conversation with the engineering team rather than a catalogue item - tell us what the pack has to speak to.
Design and sampling come first, then validation, then production, and the length of each depends on how far the pack sits from something already built. A variation on a current model moves quickly; a new enclosure, a new cell format or a certification requirement adds time before anything can be produced in volume. Manufacturing happens in Noida rather than through an importer, which is the part that usually decides the schedule: a specification change is a conversation with the people building the pack, not a change order sent abroad waiting on a shipping window.
Voltage, energy or runtime, the space it has to fit and what it reports to. If you have a drawing or a datasheet, say so and we will tell you where to send it.
