MODEL OVERVIEW
LG E78 78Ah — Selection & Sourcing
LG E78 is a large-format pouch cell listed in the official LG reference catalog with 78Ah minimum capacity at 25°C and 0.3C, a 3.67V nominal voltage and 286Wh reference energy. Its elongated outline makes the module support and cooling layout important parts of a design review. The catalog also gives pulse and time-limited discharge figures under specific conditions. Buyers comparing LG E78 battery cells should retain those conditions when discussing busbars, thermal management and the expected duty cycle with their engineering team.
For a pouch-cell project, share the module envelope, current profile and charging schedule. The review should include tab connections, insulation, cell support and the conditions used to measure thickness. These details help turn a catalog comparison into a practical qualification plan for the finished battery pack.
BK Energy can discuss LG E78 78Ah 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, review the tab drawing, support and compression requirements, thermal contact and the current profile before selecting the cell.
- 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, review the tab drawing, support and compression requirements, thermal contact and the current profile before selecting the cell. 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 E78 78Ah 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 Pouch Cells
Compare exact specifications; a similar format does not mean the cells are interchangeable.
