Since I don't know where you are in your vaping journey I will keep to the entry level batteries. Those would be the KR808-D1 and the Echo. The only problem with going fo 808 threading is that 510 and eGo threading seem to have won the larger market share which means they are more adaptable and have more accessories than the 808s. YMMV
