Qualified Lithium-Ion Cell Supply for Defense Contractors, Integrators & Manufacturers
Reliable access to major lithium-ion cell manufacturers — with the documentation and traceability needed for serious manufacturing programs.
18650 Battery Partners works with established cell manufacturers and authorized supply channels to help defense contractors, government suppliers, engineering firms, and battery manufacturers source OEM lithium-ion cells with appropriate technical, compliance, and supply-chain documentation.
We work alongside leading manufacturers and supply partners including:
Hohm Tech • Samsung • Sanyo/Panasonic • Molicel • LG
Whether you are developing a new battery system, replacing cells in an existing design, or sourcing cells for ongoing production, our goal is to provide more than just the cells.
We help provide the documentation needed to qualify, receive, inspect, trace, and manufacture with your battery cells.
DOCUMENTATION SUPPORT
Documentation Available for Qualified Orders
Depending on the manufacturer, cell model, production lot, and supply channel, we can help provide or obtain applicable documentation such as:
01 — Manufacturer Datasheet
Official technical information for the specific cell model.
02 — Detailed Cell Specification
Electrical, mechanical, environmental, charging, discharge, and performance specifications where available.
03 — UL Certification / Recognition
Applicable UL certification or recognition documentation when available for the specific cell or manufacturer.
04 — IEC / CB Certification
Applicable IEC and CB certification documentation.
05 — UN 38.3 Test Summary
Manufacturer-issued transportation safety documentation applicable to lithium-ion cells.
06 — SDS
Safety Data Sheet / Material Safety Data Sheet documentation.
07 — Certificate of Conformance
Manufacturer-issued Certificate of Conformance (CoC), when available.
08 — Certificate of Origin
Country-of-origin documentation when available and applicable.
09 — Lot / Batch Traceability
Documentation connecting supplied cells to their production lot or batch.
10 — Production Date / Date Code
Available manufacturing date, date-code, or production identification information.
11 — Quality / Inspection Report
Available manufacturer or supplier quality-control and inspection documentation.
12 — Capacity & IR Test / Binning Report
Available testing, capacity grading, internal-resistance measurements, or binning information, when applicable.
13 — RoHS / REACH Documentation
Applicable environmental and chemical compliance documentation.
Available documentation establishing the authorized supply channel or manufacturer relationship.
LOT-LEVEL TRACEABILITY
Know What You Are Receiving
For production battery applications, traceability can be just as important as the cell's electrical specifications.
When available, we work to provide documentation identifying:
Manufacturer → Cell Model → Production Lot → Date Code → Shipment
This can help manufacturers maintain internal purchasing, quality-control, and production records.
Traceability Information May Include:
Manufacturer
Cell model
Production lot / batch
Date code
Manufacturing date
Original packaging information
Carton identification
Quantity per carton
Lot identification
Shipping documentation
Applicable inspection records
Documentation availability varies by manufacturer, model, production run, and supply channel.
MANUFACTURER TEST & QUALITY INFORMATION
Documentation Beyond the Datasheet
When available from the manufacturer or applicable supply channel, we can help obtain production-lot information such as:
Capacity Grading / Binning
Information regarding how cells were capacity-tested, graded, or grouped during manufacturing.
Internal Resistance
Available internal-resistance measurements or test records associated with the applicable production lot.
Lot / Date-Code Traceability
Identification connecting the supplied cells to their manufacturing lot and production date.
Pre-Shipment Inspection
Available manufacturer or supplier inspection and sampling procedures performed before shipment.
Production-Lot Test Records
Available manufacturer test records associated with the production lot prior to shipment.
Availability of individual test records depends on the manufacturer's documentation practices and the specific production lot.

LG
Major lithium-ion cell manufacturer with a broad portfolio of cylindrical cell technologies.
Cell availability, production dates, documentation, and supply channels vary by model and production run.
FROM CELL SOURCING TO MANUFACTURING
Supporting the Companies That Build With Cells
We don't simply sell individual batteries.
We assist manufacturers, battery-pack builders, engineering firms, integrators, and qualified commercial customers sourcing cells for production applications.
Our role can include:
CELL SOURCING Identify appropriate cell models based on voltage, capacity, discharge requirements, physical dimensions, and application requirements.
DOCUMENTATION Help identify and obtain available manufacturer specifications, certifications, compliance documents, and supply-chain records.
TRACEABILITY Help establish lot, batch, date-code, and packaging traceability for production orders.
QUALITY INFORMATION Help obtain available capacity, internal-resistance, inspection, and production-lot information.
BULK PROCUREMENT Support larger production requirements and recurring cell purchases.
PRE-SHIPMENT DOCUMENTATION Where available, documentation can be reviewed and assembled prior to shipment.
FOR DEFENSE & GOVERNMENT SUPPLY CHAINS
Designed for Procurement Requirements That Go Beyond a Product Page
If your organization requires documentation before approving a battery cell for production, tell us what your procurement or engineering team requires.
We can work with the applicable manufacturer or supply channel to determine what documentation is available for the specific cell and production lot.
Typical Qualification Questions
What cell are you purchasing? Model, chemistry, size, capacity, discharge requirements, and application.
What documentation does your organization require? Specifications, certifications, compliance records, CoC, traceability, testing, or other procurement requirements.
What level of lot traceability is required? Production date, lot number, carton identification, or additional records.
Do you require documentation before shipment? Let us know during the quotation process so we can determine what can be obtained.
A BETTER WAY TO SOURCE PRODUCTION CELLS
Don't Wait Until After Delivery to Ask for Documentation
For qualified manufacturing programs, documentation requirements should be established before the purchase order is finalized.
We recommend providing your documentation requirements during the quotation stage.
This allows us to determine:
What documentation is available
Which documents are manufacturer-issued
Which documents are applicable to the selected cell
What lot-level information can be provided
Whether additional documentation can be requested
What information can be supplied before shipment
Documentation availability is subject to the manufacturer and specific production lot.
NOT AN EV BATTERY SUPPLIER
Our Focus Is Manufacturing & Battery-Pack Builders
We do not provide battery-cell support or sourcing services specifically for EV manufacturers.
Our focus is on supplying cells to:
Defense contractors
Government suppliers
Battery-pack manufacturers
Battery-module builders
Industrial manufacturers
Engineering firms
Equipment manufacturers
Power-system integrators
Commercial OEMs
Qualified production customers
If your company manufactures or builds products using cylindrical lithium-ion cells, we can help determine whether we can support your requirements.
