I am new to this forum and have been looking around to find out about my v2 cig items. Are there any tanks I can us with these batteries--I believe they are KR808D and after looking around I am confused as to what is available to use with these batteries. I have purchased 4 batteries (for my wife and myself) we have the clear carts which are working fine and also have the ones which came with the starter kit--they are unused and unopened--we were smoking a min of 1 1/2 packs of cigs per day each--she is on the .6 nic and I am on the 0 nic--glad we went to these ecigs--. Would like info on a better batteries and possibly larger tanks--what we have is working fine just want to get a battery which last as long as our money while at the casino--hate to leave and have to change batteries while playing cards. Any help would be appreciated. Thanks.
