Highest quality KR808 battery? (Which manufacturer; Kanger, Boge, etc?)

[Adub]

Hello Veterans! I am trying to figure out who makes (not sells) the highest quality kr batteries -- quality meaning: battery longevity, charging uniformity, consistent output, etc. I've done a ton of board-reading to no avail!

I know Kanger made the original but with all the "copy-catting" going on I'm sure the other companies have all put a clone on the market as well. So who makes the dependable unit?
I'm hoping to figure this out and then place a small bulk order directly from China to save some $$$. These units are for a group of people who aren't really in a financial position to make several purchases to find one that works so I want them to be the absolute best!

Any advice will be greatly appreciated!

It can be hard to track down the original manufacture w/ all the copying. I don't know if you're looking for auto or manual but I've heard (don't know for sure) that Eigate in Hong Kong makes the new auto batteries for Bloog. They have a newly designed auto switch that requires a shorter draw.

With any mass produced item there's bound to be inconsistencies, so keep that in mind.
