Will a Dorado 440 battery fit an Aventon Pace 500?

I measured my Aventon Pace 500 battery (1st gen) and as far as I can tell it's the same measurements as a Dorado 440 battery. Anyone ever use the Dorado 440 in a Pace 500?

In case anyone comes across this thread,
Jenny from Aijiu Battery tells me the 1st gen Pace 500 takes the Reention Dorado L440 battery. They have a new 20ah model which would be a big improvement over the original 11.6 ah battery for $600 with free shipping. It uses Samsung 21600 cells. From what I've read Aijiu makes a quality battery. When the time comes to replace my original battery, I'll likely go with this one.
