From an 11.1V handheld pack to a 74V traction pack — LFP or NMC, cylindrical or prismatic, in the enclosure and footprint your product needs. No minimum order.
We assemble to specification rather than to a catalogue, so the useful question is not which model you need but what the pack has to do. Here is the envelope we work inside.
LFP and NMC, chosen for the duty cycle rather than whatever is on the shelf.
Cylindrical 18650, 21700, 32700 and 32140, or prismatic LFP from 105Ah to 314Ah.
Any series and parallel arrangement — a 3-cell pack or a several-hundred-cell pack.
ABS or MS, sized to the space you have and the mounting you need.
Smart BMS with cell-level monitoring, balancing and charge/discharge protection.
No minimum. A single prototype is a job we will take.
Enter the voltage and capacity you need and pick a cell. The panel shows the series and parallel configuration that gets you there, the resulting pack voltage and energy, and how the cells are laid out. Send it to us and we will take it from there.
Passed to our team with your enquiry so we can size the BMS and pick the right cell.
We will come back on this configuration. Leave us a number and we will take it from there.
Our team will get back to you on it. If it is urgent, call sales on +91 70443 59004.
Indicative configuration for guidance only. Final design, cell selection, enclosure and BMS are confirmed by our engineering team. Weight, dimensions and price depend on cell make and enclosure.
Different industries, same question every time — how much energy, in how much space, at what current. If your application is not here, it is worth asking anyway.
Five steps, and you can stop after any of them. Most customers start with a single prototype — there is no minimum order to clear first.
You tell us voltage, capacity, continuous and peak current, the space the pack has to fit, the connector, the charger and the operating temperature. The configurator above covers the first two; the rest we take on a call.
We select the cell and chemistry, work out the series and parallel arrangement, size the BMS and specify the enclosure and interconnects. You get the configuration and the bill of materials before anything is built.
We build a sample to the agreed design. You put it in the product and find out what we both missed — mounting, cable exit, connector orientation. Changes at this stage are cheap.
The prototype is tested for capacity and load behaviour, and the BMS settings are confirmed against how the pack is actually used.
The design is frozen and packs are built to it, tested individually before dispatch. Repeat orders come off the same frozen specification.
Send us the voltage, capacity, current, space and connector — or just describe the product and we will work out the rest. A single prototype is a job we will take.
Talk to our team →Custom work is mostly about whether the people building it will take your job seriously at your volume. Six things that decide that.
Yes. Packs are built from the series and parallel arrangement your requirement needs, in LFP or NMC, using cylindrical or prismatic cells. Use the configurator above to see the configuration for your voltage and capacity.
No. A single prototype is a job we will take, and most custom work starts that way.
LFP gives longer cycle life and greater thermal stability; NMC gives more energy in less space and weight. If the product has room and charges daily, LFP usually wins. If it is handheld or weight-critical, NMC usually does.
Cylindrical cells in 18650, 21700, 32700 and 32140 formats, and prismatic LFP cells from 105Ah to 314Ah. If you have a cell you want us to use, we can work with that too.
ABS or MS, sized to the space and mounting your product needs. The enclosure is specified as part of the design rather than picked from a shelf.
Voltage, capacity, continuous and peak current, the space the pack has to fit, the connector, the charger and the operating temperature range. If you do not have all of it, describe the product and we will work through it with you.
Prototypes are quoted per job, based on the cells, BMS and enclosure involved. We confirm the cost with the design before anything is built.
Lead time depends on the configuration and cell availability at the time of order. We confirm a timeline when the design is agreed.
Warranty is agreed per project, based on the chemistry, the duty cycle and the application, and confirmed in writing with the quotation.
Send us the specification, or just describe the product and what it has to run. One pack or ten thousand — both start the same way.
