I just ordered a maxx fusion set up yesterday. I have never tried an ecig before. I ordered 2 65mm batteries and a 3 different flavors of 24 mg carts I'm used to smoking 1.5 to 2 pad of Newports. I was wondering if 2 batts will get me trough a day. I got the usb wall charger and the car charger. The pcc was not available, but I intend to get it when it is if ecigs work for me. How well do these batteries do for you guys? How long will a 65mm battery last on a charge? DO they hold their charge if you have extras charged just in case, but don't use them? Do you think I should have more that 2? Also, what is the total length cart and battery? Is it about the same size as an analog? Thanks
