I saw the price of those
batteries yesterday at Smoke 51 - worst case of jacking up prices I have ever seen. $50 per battery.
Supposedly, Smoke 51 is "compatible" with E9 which is not a popular e-cigarette.
Scroll down to the E9
Brand and Model Compatibility Chart - E-Cigarette Wiki
E9 is a cheap e-cigarette I have only seen sold at Chinese wholesalers. (cheap like 11.95 for a starter kit) and they only seem to offer tan carts (cartos?) and white batteries. The batteries sold at Smoke51, if they are indeed E9 batteries, may have had their look customized for Smoke51.
Anyway, E9 e-cigarette's batteries might work for you if you can find them.
This Chinese co seems to sell them but they may be a wholesaler and you can search Google for E9 E-cigarette to find more - maybe you could get a big cheap bunch of replacements and supplies.

If you like cartomizers, you might want to check out the KR808D-1 which is also sold by Vapor4Life as its "Vapor King" in larger variety of colors. it would not be compatible with what you have already. I found their Premium cartos to be too hot on my lips, and I have have not tried their Coolcarts yet. You can also get blank cartomizers elsewhere for KR808D-1 and some people prefr the Boge one (I think same as Coolcarts)

And grats on switching to e-cigarettes an sticking with it. I wish they existed when my Mom has her THR. She was stuck in the hospital a month because they tried pins first. She told me she wanted a tall stiff drink and a really long cigarette.
