Distributors, pack integrators, and energy-storage buyers can use this guide as a factory-sourcing brief: it explains what to verify when you purchase a wholesale LiFePO4 battery cell, and how to qualify iBorn Energy as a LiFePO4 battery cell manufacturer — using the IFR21700-3000mAh rechargeable cylindrical cell as the benchmark for your procurement comparison.
Wholesale buyers do not just compare price per cell; they compare data availability, documentation, and the factory's ability to deliver consistent grade-A product.
Every quote should reference the same measurable parameters: model, voltage, capacity, dimensions, resistance, and cycle life.
iBorn states that its brand-new grade-A cells can guarantee 6000 lifecycles — roughly 12 times the cycle life of a lead-acid battery.
A manufacturer-led supplier can share safety, environmental, quality, and transport documentation with each inquiry.

Each project type places a different demand on the cell. Use the scenario cards below to connect your use case to a specific IFR21700 spec — and to the decision that matters for your order.
For household and commercial storage racks, the relevant facts are the 3.2V nominal voltage, 3000mAh capacity, and the ≥ 6000-cycle rating at ≥ 80% of initial capacity.
For e-scooters, e-bikes, golf carts, RVs, and trolling motors, the key facts are 9.6A continuous discharge (16A peak), a -20°C to 60°C discharge window, and an approx. 64g cell weight for pack design.
For standby systems, iBorn highlights good performance in high and low temperatures, zero maintenance requirements, and eco-friendly construction.
Certificates are part of the commercial order, not an afterthought. The IFR21700 product page lists the following documentation categories.
CE, CB, IEC62133, UL, PSE
ROHS, REACH
ISO9001, ISO14001, BSCI
