Unmatched Capacity: Amprius SA112 21700 6500mAh – Now Available from BECELL

In the rapidly evolving world of lithium-ion batteries, capacity and energy density are the ultimate differentiators. BECELL is proud to announce that we hold massive inventory of the Amprius SA112, a 21700 rechargeable cell that sets a new benchmark for high-capacity cylindrical batteries.

With a typical capacity of 6500mAh (22.5Wh) and a minimum of 6350mAh, the Amprius SA112 is currently the highest capacity 21700 cell on the market. Its nominal voltage of 3.46V and charge voltage of 4.2V make it a drop-in upgrade for existing 21700-based packs, delivering up to 8-10% more runtime than conventional 6000mAh cells.

Real-World Performance Verified

We have conducted independent charge-discharge tests under CCCV 0.5C charge / 0.2C discharge conditions at room temperature. The results confirm effective usable capacity of 6500mAh – no exaggerated claims, just real energy you can rely on.

Technical Highlights

• Energy Density: 315 Wh/kg (gravimetric) / 860 Wh/L (volumetric)

• Internal Resistance (ACIR): ≤22 mΩ @ 1kHz, 30% SOC

• Max Continuous Discharge: 13A (2C)

• Max Pulse Discharge (30s): 26A (4C)

• Charge Current: 3.25A typical / 4.55A max

• Cycle Life: 500 cycles @ 3A/7.5A (4.2V–2.75V, 80% SOH); 1000 cycles @ 0.5C/1C, 70% DOD, 90% SOH

• Operating Temperature: Discharge -20~60°C / Charge 0~45°C

• Weight: 72±1g

• Certifications: UN38.3, IEC62133, PSE, CE* (*Q4 2025)

Head-to-Head: SA112 vs. Leading 6000mAh 21700 Cells

We compared the SA112 against three popular “high-capacity” 21700 models from Far East (FEB 21700-6000mAh), Joinsun (INR21700-60D), and Reliance (INR21700-RH60). All three are rated at 6000mAh (typical) with nominal voltages of 3.60V.

Note: Reliance RH60 offers excellent discharge current (20A) but lower typical capacity (~5850mAh min). SA112 balances high energy with moderate power – ideal for applications demanding longer runtime without extreme discharge rates.

The SA112 delivers +8.3% more capacity than 6000mAh cells while maintaining competitive internal resistance and cycle life. For energy-starved applications, this difference translates into significantly longer operation between charges.
