Choosing Between Li-ion Cell Brands
No brand is best for every pack. The right cell depends on the current your device draws, the capacity you need and the documents your customer asks for. Jetray supplies cells from Panasonic, Samsung, LG, Molicel and EVE and helps pick between them.

Brands we supply
These are market impressions, not a ranking. Compare the exact model's datasheet before you decide.
Compare the model, not the brand
Each brand makes capacity cells and power cells. For a given size, compare:
Which fits which job
Counterfeits and sourcing
Loose cells of well-known names are often faked. Buy through a supplier that can show where the cells come from, and ask for the datasheet and batch information. We tell you what we recommend for your load and why.
Not sure which cell?
Send the device, voltage, peak current and space. We recommend a cell and reply within 24 hours.
Cells in a pack
Use matched cells in one pack: same brand, model and batch, sorted by capacity and internal resistance. A pack with mismatched cells ages unevenly.
What a pack customer needs from the cell supplier
- The datasheet for the exact cell model.
- Proof of origin for the batch.
- Consistent supply over the product's life.
- Packing and labels that suit transport.
- A plan if a model is changed or ends production.
How we recommend a cell
- 01
You give us the device, the voltage and the peak current.
- 02
We shortlist two or three cells from the brands we supply.
- 03
We compare capacity, current, size, temperature and cost per pack.
- 04
We build a sample with the best candidate, and you test it.
- 05
We lock the model for production and tell you before any change.
Supply planning
If your product will run for years, tell us the yearly volume. We plan the cell supply with you, so a model change does not catch you by surprise.
Frequently asked questions
It depends on the controller's current and the space. Send the motor and controller details and we recommend a cell.
No. A higher capacity cell may allow less current. Check the continuous discharge rating.
Yes. We can quote two or three options for your load.
Yes, for the cell model we quote.
Yes. Send the model and we confirm if we can supply it.
We suggest a replacement and build a new sample for you to test.
We check cells by capacity and internal resistance when matching them for a pack.
Not sure which cell?
Send the device, voltage, peak current and space. We recommend a cell and reply within 24 hours.
