I own a KR808d1 and I'm curious to know if the kr8 cartos would be compatible with a 510 battery. Also would they work with the bigger 510 batteries like the ego? ok for the heck of it just tell me about any carto compatibility you know of! I'm stressing about my next starter kit purchase. I thought I had it narrowed down and then I spent another day reading posts in this forum. I think I'm addicted and am going to start collecting models
