MODEL OVERVIEW
LG 18650-HG2 — Selection & Sourcing
LG HG2 is a 3000mAh nominal 18650 lithium-ion cell with a 3.6V nominal voltage and a 20A continuous discharge rating in the reviewed LG Chem specification. Power tools are the stated application in that document. For cordless appliances or another OEM pack, compare the expected current and heat accumulation with the complete operating conditions. The reference is an older revision and uses a 2.5V discharge cut-off; that limit should be checked against the exact revision supplied rather than silently mixed with another datasheet.
For an OEM battery pack, provide the series and parallel arrangement, continuous load, peak duration and charging schedule. That information makes it easier to compare usable energy, thermal behavior and the required protection settings. Qualification should reflect the finished equipment rather than a single headline rating.
BK Energy can discuss LG 18650-HG2 wholesale sourcing with your purchasing team. Include the sample quantity, expected production volume, delivery destination and documents needed for supplier approval so the quotation addresses both technical and commercial requirements.

What to Check for Your Pack
For these project types, compare the continuous load, repeated peaks, charger settings and measured pack temperatures with the exact cell revision.
- Energy and load: usable energy, continuous current, peak duration and charging opportunities.
- Mechanical and thermal fit: the exact drawing, connections, enclosure temperature and cooling arrangement.
- Qualification: a test plan based on the finished equipment, including its protection settings and required approvals.
PROCUREMENT DOCUMENTS
Datasheet, Traceability & Certificates
Ask for the specification and drawing that match the offered lot. If your project needs a UN 38.3 test summary, SDS or a particular cell certificate, include that requirement in the enquiry.
BUYER QUESTIONS
Before You Order
Is this cell suitable for my application?
For these project types, compare the continuous load, repeated peaks, charger settings and measured pack temperatures with the exact cell revision. Application names on this page are evaluation starting points, not a claim that an OEM has approved this exact cell.
Can I get the LG 18650-HG2 datasheet?
Yes—send the complete model code and your project requirements. We will review the matching specification and available documentation with you. Any preliminary values should be confirmed before production approval.
What are the wholesale price, MOQ and lead time?
These are quoted for the requested model, quantity, available lot and destination. Send sample demand and expected production volume so the offer can address your schedule.
Which documents should accompany the order?
Ask for the applicable specification revision, lot identification, SDS and UN 38.3 test summary, plus any model-specific certificates required for your market. Cell documents do not replace finished-pack or equipment approval.
Compare Other 18650 Series
Compare exact specifications; a similar format does not mean the cells are interchangeable.
