Good summary. It would have been nice to see a chart showing advertised vs actual charge times.

Also, since Ego's ace is their heat management, you should try depleting each battery in a high drain tool and seeing how long it takes to charge right after, kinda like this Ego vs Echo video:

That guy has a few other videos worth watching if you're into comparing battery platforms.

Yeah....this video was just a setup to my annual giant beachball blower bonanza.  I wanted to be able to report real world times.

Thanks mate...I almost did not post it.  I wanted to get real world charge times for these batteries in prep for my beach ball blower bonanza.  8 - 40v plus blowers and counting.

By the way, add Snapper 82V. I think that one might give EGO a run for their money because they are actually honest about their specs unlike so many other companies, notably Echo.  130mph, 550
CFM is about 18.1 Newtons of force, while 575CFM at 120mph is 17.5 Newtons.  With a ball, it is the force at a distance that counts, and force resulting from higher speed and lower volumes will dissipate more rapidly than high volume at lower speeds. This has to do with transfers of kinetic energy.  The statement that I have underlined I need to confirm, I am not totally certain about its accuracy, but it is a hypotheses that I'd bet my money on.

I will note that as far as cordless blowers go, EGO's backpack blower is up there.  Challenging that one are the Greenworks Commercial GB-600 and GBB-600 blowers.  One is a handheld unit that connects to a backpack battery and possibly a hip-mounted battery, and one is a backpack blower.

As far as charge times go, what matters most in my book is how many watt-hours per unit time the battery gains on average, though it can get complicated when efficiency of tools comes into play, but the baseline number is watt-hours per unit time, which EGO wins with the rapid charger only when it charges batteries 4Ah or larger, otherwise, the 80V stuff wins (Greenworks Pro 80V, Greenworks Commercial 82V, Snapper XD 82V, Kobalt 80V).
