Cell Matching & Inspection
For multi-cell battery packs, consistency matters. AmpBird can coordinate pre-shipment checks for open-circuit voltage, internal resistance, physical condition and batch consistency according to the agreed order requirements. Capacity testing or additional inspection should be confirmed before ordering when required.

Why Choose AmpBird Cells
The foundation of every great battery build.
LiFePO4 Chemistry
Thermal stable, non-flammable, 3,000-8,000 cycle lifespan. The only safe choice for home energy storage.
Grade A Cells Only
Every cell batch-tested for capacity, internal resistance, and voltage before shipping. No B-grade, no surprises.
Deep Cycle Ready
Designed for 80% DoD daily discharge. Solar cycling, off-grid loads, and backup power -- built for real use.
-20℃ to 60℃ Operating
Wide temperature tolerance. Reliable in unheated garages, outdoor cabinets, and marine environments.
Compact Prismatic Form
Prismatic cells stack efficiently with minimal wasted space. Higher energy density than cylindrical cells.
Low Self-Discharge
< 3% monthly self-discharge rate. Store seasonally and come back to a full charge.
