Product Description
This cell is part of BYD's Blade Battery LiFePO4 lineup — a flat, elongated form factor that offers a larger heat-dissipation surface and better space utilization than conventional square prismatic cells. This 340Ah version packs high capacity into an ultra-thin 20mm profile, making it a strong fit for storage applications with strict installation depth limits that still need serious capacity. This listing is the stud terminal with connector plate version — the cell ships with welded stud terminals and comes with the connector plate included, ready for series assembly without sourcing separate connectors.

How to Verify You've Received a Genuine Cell
-
Weight and dimensions: genuine cells should be close to 5.3kg and 580x215x20mm — a meaningful deviation is worth questioning.
-
Connector plate included: the connector plate ships with this listing, so you shouldn't need to source one separately. If you have specific current-carrying requirements for the connector plate, confirm with customer service before ordering.
Where This Cell Fits
-
High-capacity home energy storage packs — high capacity combined with an ultra-thin profile suits installations with limited space
-
Thin-profile and wall-mounted storage cabinets — the 20mm thickness is well-suited to embedded or wall-mounted installations
-
RV and marine power systems — the flat form factor fits well in narrow spaces
- DIY battery pack builds
System Integration Notes
-
Series configuration: 16 cells in series (16S) gives a nominal 51.2V pack.
-
Structural mounting: blade cells carry some structural load as part of their design — plan your top and bottom clamping plates accordingly rather than assuming the same assembly approach as square prismatic cells.
-
Stud torque: The default is M6, and others can be customized.

Frequently Asked Questions
Is the connector plate included, or sold separately? This listing is the stud terminal with connector plate version — the connector plate ships included with the cell.
Is the pack assembly process the same as with square LiFePO4 cells? Not exactly. Blade cells carry some structural load as part of the design, so the mounting approach differs from square prismatic cells — plan your top and bottom clamping plates accordingly before assembly.
How many cells do I need for a 48V system? 16 cells in series (16S) gives a nominal 51.2V pack.
