Size your pack before you commit.
Most suppliers quote you a cell. We calculate the whole configuration — series, parallel strings, cell count, and how much of your budget a bigger can saves. Two schemes side by side, in the browser, in under a minute.
Nothing is uploaded. The calculation runs locally in your browser against our stock list.
Cost index is relative to a single-standard 280 Ah supply and covers cell cost only, not BMS, enclosure or freight. Figures are indicative until confirmed in a written quotation.
Start from the job, not the catalogue.
A cell that is perfect for a container BESS is the wrong cell for a power tool. We group stock by what it has to survive — instant current, continuous load, or fifteen years of daily cycling.
Every budget gets a real cell, not a downgrade.
We do not rank manufacturers as good or bad — we rank them by fit. The same 314 Ah capacity exists at three price points, and the right answer depends on whether the project is financed, tendered, or built to a hard cost target.
Economy line
Volume orders where the BOM is fixed and the margin is thin.
- Lowest cost per Ah in class
- 3,000–8,000 cycles depending on format
- Deep stock, short allocation windows
Mainstream line
The default choice for projects that must not fail and must still price.
- Best supply depth and second-source options
- Consistent grading lot to lot
- Documentation accepted by most importers
Premium line
Bankable cells for financed assets and warranty-critical contracts.
- Highest density and cycle rating
- Preferred by EPCs and insurers
- Longer lead time, firmer allocation
The same requirement, a cheaper pack.
Every case below started as a customer drawing with a cell already chosen. We re-ran the selection and found fewer cells for the same kilowatt-hours.
Eight things a trading company cannot copy in a week.
Batch QR traceability
Every carton maps to a cell batch, a grading report and a production date.
Pre-shipment inspection
Voltage, IR and capacity sampling on every lot, with photos before loading.
Selection engineering
We size series and parallel strings against your drawing, for free.
One-stop across three formats
Prismatic main line, cylindrical 18650/21700, pouch on request — one B/L.
Export documents ready
MSDS, UN38.3, IEC 62619, CO, packing list and DGD handled in-house.
Samples in days
Qualification cells leave Shenzhen within 3–5 working days, DDP available.
Allocation, not promises
Stock and allocation confirmed in writing before you open the L/C.
One engineer, one thread
After-sales goes to the person who sized your pack, not a shared inbox.
Shenzhen warehouse
Stock you can inspect before you pay.
Cells are held in our own Shenzhen consolidation space, not drop-shipped from a factory we have never visited. Mixed orders are picked, labelled and photographed here before they go to the forwarder.
Tell us the project. We will send the cell plan, not a price list.
Voltage, energy, application, budget — four lines is enough for us to come back with a sized configuration, a lead time and a firm quotation.
