MODEL OVERVIEW
LG 21700-M58T — Selection & Sourcing
LG M58T is a 21700 lithium-ion cell with a 20.0Wh minimum energy requirement in the reviewed specification, subject to its stated formation and initial-cycle conditions. The nominal voltage is 3.59V. This makes the LG M58T datasheet especially useful for teams comparing energy-focused cells for mobile equipment and e-bike pack development. Maximum full-discharge current varies with ambient temperature; the 12.5A value applies from 0 to 35°C. Capacity labels alone do not capture those conditions or the energy available at your application's actual load.
For a 21700 battery pack, share the series and parallel arrangement, continuous load and charging schedule. Check cell temperatures under the repeated duty cycle as well as brief peaks. This gives your engineering team a useful basis for comparing models and setting the sample qualification plan.
BK Energy can discuss LG 21700-M58T 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.

APPLICATION REVIEW
What to Check for Your Pack
For these project types, compare usable energy at the working load, cell-holder tolerances, busbar design and the temperature-dependent operating limits.
- 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 usable energy at the working load, cell-holder tolerances, busbar design and the temperature-dependent operating limits. 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 21700-M58T 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.
