Chartz:"well, that's the point. The echo-e (for the ego/510 thread) isn't as nice as the regular echo on my new 808 threaded echo battery. Unfortunately the echo-e won't fit for some reason on my 808 to 510 adapter so I can't tell if it's the battery or the cart."
It's a shame your adapter doesn't fit as that would let you make a direct comparison on the same battery. Some batteries come with a preset voltage limit as low as 3.2v and most have a range from 4.2v fully charged to a 3.2v discharged. If you are vaping your Echo E at a lower voltage that would make a significant difference. To know for sure what you have you will have to test your batteries with a volt meter.
I find this Volt Indicator from Mad Vapes to be invaluable. It can be screwed on to the battery to check voltage and a atty/carto screwed into the other end to check voltage under load.
