Grade‑A LiFePO4 prismatic and cylindrical cells for pack builders, ESS integrators and distributors — graded on capacity and internal resistance, shipped with per‑cell test data your production line can trust. As a direct LiFePO4 cell supplier we sort the batch so you don’t.

Cell range overview

Prismatic cells

50 / 100 / 105 / 230 / 280 / 304 / 314Ah. High energy density and easy to stack into 24V / 48V / 51.2V blocks.

Cylindrical cells

18650, 21700, 26650 and 32700 for high‑discharge and standard‑holder applications, including 18650 cells bulk supply.

Sodium‑ion option

Cold‑climate and cost‑sensitive projects can move to sodium‑ion cells without redesigning the enclosure.

Matched modules

12V / 24V / 48V / 51.2V modules and smart BMS, pre‑balanced and documented for drop‑in integration.

Capacity options

Pick the form factor your enclosure was designed around. 280Ah and 314Ah drop into most residential and small C&I builds; 50–105Ah suit portable and specialty packs.

Grade‑A sourcing & grading

We don’t pull cells off a pallet and call them Grade‑A. Every order is graded on three things that decide pack life: verified capacity above nameplate, matched internal resistance and self‑discharge within band. The result ships as one batch with one test report, keyed to serial numbers.
  • Capacity verified above nameplate — more usable kWh before first degradation.
  • Internal resistance matched per batch to keep parallel strings balanced.
  • Per‑cell test data supplied with every shipment, not on request.
  • Laser‑welded terminals and busbars, or bare cells for your own welding.

Why source cells from EGbatt

One quality system

Grading, assembly, BMS and test data live in‑house — prototype equals production.

Batch traceability

Serial‑keyed reports let your line skip incoming sorting.
