Aw man I'm always pumped about new Mooch batteries. Can't wait till the next wave of 21700 batteries that'll hit 4000mah at 30A!
I currently use the Golisi S35 21700 battery from Heaven Gifts. I love it! I vape at ~50 watts and that lasts me for about 250 two second puffs. I have a short review of it appended to my Hugo Vapor Urus review.
