Once a buyer has compared the spec sheets, the next round of questions is almost always the same: what is the minimum order, how long until it ships, what documents come with it, and who pays for what between the factory gate and the destination port. Getting those four answers right in the first reply shortens a deal by weeks.
This is how we handle each of them, written down so it can be checked against the quotation.
Minimum order: per model, not per container
Our production minimum is 20 units per model. It is set by the line, not by a sales target: below that, the changeover, aging and testing time per unit stops making sense. Mixed orders are normal — a distributor might take three models at 20 units each rather than 60 of one. Custom configurations and OEM labelling are quoted separately, because tooling and labelling costs do not scale the same way.
Lead time: counted from deposit, not from the inquiry
Standard production runs 25 days from the date the deposit clears. That window covers cell allocation, assembly, aging and outgoing inspection, and it is the number we put in writing. Two things move it: cell batch availability for less common capacities, and any customisation that requires new tooling or a new BMS configuration. Both are confirmed before the order is accepted rather than discovered afterwards.
Incoterms: what each one actually hands over
We quote EXW, FOB and CIF. The difference is not cosmetic. Under EXW the buyer’s forwarder collects from the factory and carries export clearance; under FOB we deliver cleared for export onto the vessel; under CIF we also pay freight and insurance to the destination port. For a first shipment, FOB is usually the cleanest split of responsibility: the buyer controls the forwarder and sees the real freight cost, while export paperwork stays on our side.
Lithium cells are Class 9 dangerous goods, so the forwarder must accept UN3480 (cells and packs shipped alone) or UN3481 (packed with equipment). Not every consolidator does, and the ones that do often charge a surcharge. Confirm the forwarder before the goods are ready, not after.
Documents that travel with the shipment
Every order ships with a commercial invoice, packing list and the transport documents the forwarder requires. For the battery itself we provide the UN38.3 test summary and the MSDS, which is what carriers and customs ask for. Where the destination requires conformity evidence, we provide the CE Declaration of Conformity covering LVD and EMC — issued by UDEM, certificate number M.2026.206.C143410, valid to 29 June 2031, covering models YD-24-314, YD-48-314 and YD-80-340 — and we design to IEC 62619 where the application calls for it.
One clarification we make in writing every time: listing a standard is not the same as holding every certificate for every model. The documents that exist for the specific model you order are confirmed with the quotation, and no certificate is implied beyond that.
Warranty: what the term covers
Packs carry a 3 to 5 year warranty depending on the product line; stationary storage systems carry 5 years, extendable to 8. The term is measured from shipment, and it covers capacity retention and workmanship under the operating conditions stated in the specification sheet — not damage from over-voltage, water ingress outside the IP rating, or unauthorised BMS changes.
What we need from you to quote accurately
- Application and load profile: continuous and peak current, daily energy, duty cycle.
- System voltage and the charger or inverter already in use, with model numbers.
- Destination country and port, so the Incoterm and freight can be quoted together.
- Any certification the destination requires, before we confirm feasibility.
- Labelling and packaging requirements, if the units carry your brand.
With those five items, a quotation is normally back within two working days, with the matching configuration and the specification sheet attached.
The configuration most often quoted for fleet pilots is the 48V 24Ah swappable pack. Certificates and transport documents are listed in the download centre.
