Product Description
This is the 150Ah version of BYD's Long Blade LiFePO4 cell — the flat, elongated blade design gives it a larger heat-dissipation surface and better space utilization than conventional square/prismatic cells at the same capacity. This listing is explicitly Grade A (genuine, full-spec cells), in 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.

A note on discharge rate: the max continuous discharge rate is 3C, which works out to roughly 450A on this 150Ah cell — this is the current the cell can sustain continuously, and it's a reasonable figure to design your BMS and busbars around.
How to Verify You've Received a Genuine, Grade A Cell
-
Grade confirmation: this listing is explicitly Grade A — ask your supplier for grade documentation or batch information before ordering if that matters for your project.
-
Weight and dimensions: genuine cells should be close to 2.7kg and 960x90x13.5mm — 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 — strong capacity and sustained current output for performance-focused storage builds
-
RV and marine power systems — the flat, elongated shape fits well in narrow spaces like boat hull cavities or RV chassis compartments
- Low-speed vehicle and golf cart battery packs
-
Thin-profile storage cabinets — where you need to fit high capacity into a limited depth
System Integration Notes
-
Series configuration: 16 cells in series (16S) gives a nominal 51.2V pack, the same configuration logic as other LiFePO4 cells.
-
Structural mounting: blade cells carry some structural load as part of BYD's cell-to-pack design philosophy — plan your top and bottom clamping plates accordingly rather than assuming the same assembly approach as square prismatic cells.
-
BMS selection: size your BMS and busbars around the 3C continuous discharge rating (~450A).
-
Stud torque: the data card doesn't specify a torque value — confirm the stud spec and recommended torque with customer service before assembly.
Bulk orders: available for full pack builds or with BMS integration — contact us for a quote on custom configurations.
Frequently Asked Questions
How do I use the 3C max continuous discharge rating in practice? 3C on this 150Ah cell works out to roughly 450A of sustained current — that's the number to design your BMS and busbars around.
What's the difference between Grade A and other grades? Grade A typically refers to cells that meet full capacity, cosmetic, and batch consistency standards for normal shipment — not disassembled or downgraded stock with capacity or cosmetic defects. Confirm specific grading criteria with customer service before ordering if this matters for your project.
How many cells do I need for a 48V system? 16 cells in series (16S) gives a nominal 51.2V pack, consistent with standard LiFePO4 pack configuration.
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.
