When I look at the source of the first post - there are image links there.
Copying a link and opening in another tab shows me image - so this is working.
However when I reload the BLF site and look at network requests - my browser tries to load the images but your server refuses to give them with error “403 Forbidden”.
I don’t know maybe your web admin added some embedding “protection”?
Anyway the issue seems to be with your image host.
Sometimes you get higher capacity at higher discharge rate because the battery “doesn’t get discharged completely”. This is why energy is a much precise way to measure the real capacity because it can be translated directly into lumens/hours.
I concur energy is a more precise way of measuring absolute performance or delivered energy.
The area below the line curve is delivered energy, which is the integral of the voltage curve over the delivered capacity for the given voltage range and discharge rate. Or something like that, haven't touched formal maths for ages.
Because of temperature induced chemistry reactions inside the cell. As a general rule heat improves the performance to some extent, chemistry dependent of course. While lots of modern cells do not show increased capacity at larger discharge ratios, increased heat reduction in internal resistance is common.
That was my thought as well. I have seen li-ions that were cold and run under a 3 amp discharge actual slightly increase in voltage as they were being discharged because the internal heat from being discharged warmed the cell which gives it the ability to provide more current. Since the discharge current is constant the cell doesn’t have to work as hard warm so the voltage goes up slightly. A warm cell will give more capacity in a discharge test than a cold one in my experience.
