I went to vapcell's website, looked at their charts and specifications. I disagree with your assessment. They specify 3800mAh minimum discharge at 0.2C for their 4000mAh cell. They don't show a discharge curve at 0.2C in their charts (would be 0.8A) but they do have a 1A discharge. When the 1A discharge curve reaches 3V, the energy discharged is right around 3800mAh. Lumafield discharged at 0.2C, and they saw only 3055mAh. Vapcell's site mostly shows high current discharge curves, where yes there is more capacity below 3V available, but with Li-ion at lower currents, the curve is very steep past 3V, not much more capacity left after that. And when you're discharging at high current you won't expect to get the full capacity, anyway. I'll also take this time to point out lygte-info which is a treasure trove of battery tests. | ||
