21700 Battery Cell Comparison - 50A Constant Current Test

Interactive plots for voltage, power, temperature, and capacity under 50A CC. Tested and documented by Nelvick Berrios (DIY500AMP.COM) | 2025-12-30

How to use this page

Open any plot below. Use the legend to toggle cells on or off. Hover any line to see the exact values. The x-axis is either Time (s) or Energy (Wh) depending on the chart.

Thermal behavior

How fast each cell heats under 50A. Lower rise per Wh is better efficiency.

Voltage stability

Voltage sag under load affects usable power, controller behavior, and cutoff.

Power delivery

Shows how consistently each cell maintains output as voltage drops.

Capacity utilization

Real usable capacity at 50A. High current always reduces capacity vs datasheet.

Current stability

Confirms the discharge is constant current (CC) across the test.

Important notes

All tests shown here are 50A constant current. Temperature values are external cell measurements. Energy (Wh) is computed from measured voltage and current over time. Results reflect single-cell behavior and do not represent pack-level cooling.

Tip: Some cells end earlier on the energy axis because they reach cutoff voltage sooner at 50A.
