Compact procurement brief
Industrial lithium battery brief
Use this page to close configuration, interface and approval questions before an industrial lithium battery inquiry leaves your desk. HelioLink Sourcing will repeat the fields to factories. It will not invent a rating that the project has not chosen.
Write one line for the duty, one line for the electrical interface and one line for documents still missing. If a BOM contains inverters, chargers or mounting, keep those lines separate from the battery row.
- Specification Chemistry, usable capacity, rated power, DC voltage, thermal management.
- Quantity Racks or cabinets, plus spare modules if they are in scope.
- Destination Plant, depot or yard in the US, with indoor or outdoor stated.
- Timing Date the drawing must return, then the requested ship window.
Brief columns that stay fixed
- Specification Do not collapse chemistry and cycle-life basis into a marketing family name.
- Quantity State the unit. A pilot rack and a production lot are different rows.
- Delivered scope Currency, packaging, freight, duty treatment, cables and warranty exclusions.
- Supplier documents Datasheet and drawing for the quoted model before a listing conversation.
Files to request with the brief
An industrial lithium battery quotation is comparable only when the file names the same model the price names.
- Datasheet showing usable capacity, rated power and the discharge assumption.
- Drawing with mass, footprint and enclosure rating.
- BMS and protocol note, including what the plant controller must supply.
- Thermal management description and the ambient limits the supplier accepts.
- Applicable safety listing reference and transport test summary, each tied to the item.
- Cycle-life statement with depth of discharge and the test reference, if life is a buying condition.
Decisions the brief should leave open
Unit price versus delivered procurement scope: the lower unit figure helps only when accessories, freight and documents match. Otherwise record the gap and wait for a revised quotation.
AC-coupled versus DC-coupled storage: an AC-coupled path can suit a retrofit with an existing inverter. A DC-coupled path can remove a conversion stage in a new layout that is actually compatible. The brief records the project engineer choice. It does not treat either path as universally suitable.
Central or string conversion on the PV side, when the battery shares a site with modules, is a separate equipment row. Module-level electronics can support per-module monitoring where shading and service access justify the extra devices. That choice does not set the battery chemistry.
Round-trip efficiency, operating temperature and maximum current remain supplier statements with units. HelioLink Sourcing does not publish a site result. The project-use page and the longer note use the same rule.
Put buyer numbers on the brief only when they already exist: cycle life such as 6000 cycles at a named depth of discharge, a 1500 V DC rating, enclosure notes, and a SCADA or OCPP point if a controller is in scope. CCS or NACS belongs on a charger line, not inside the battery chemistry cell. A bidirectional inverter question stays open until the electrical engineer marks it.
Before comparing two supplier replies, freeze one requirement revision and mark each row accepted, deviating or unanswered. Compare usable capacity at the same depth of discharge, rated power at the same operating temperature, battery management system protocol and firmware, warranty exclusions, and freight to the same US destination. Ask whether MOQ, sample charges, inspection and document costs change the per-unit or whole-order budget. A qualified reviewer must approve any sample acceptance method and limits; request a revised quote when model identity or test basis differs.
