Convoy M21A vs L21A, SFT40, 8A

Please send the link for that video. I can’t find it.

With a fully charged battery the output will initially be roughly the same between an 8A linear & an 8A buck driver. The power consumption is higher for the linear driver with a fully charged cell as the excess voltage is wasted as heat. This should mean that the buck driver sustains a higher output for longer. However the buck driver will have a higher resistance than the linear driver, so the linear driver will have the edge when the cell voltage drops. I believe the buck driver should be better in practice, but I’d be very interested to see a graph comparing the two

I created a beamshot comparison between the M21E & L21B. Those should shine the same as the M21A and L21A:

This is great. Both are using 8A buck?
