Good luck with the mail!!
And some tips -
Make sure the end of your battery is dry and clean before putting it in a charger
The charger cables start red then flash red/blue then finally all blue when done charging
Never screw the battery on the charger harder then needed or it will press the pole of the battery in further
If you didn't buy
eliquid buy some now. if you keep a carto damp you can get days of use out of one. If you run them dry you will singe the stuffing and ruin the carto.
You can buy a standard resistance (not LR) DSE901 atomizer and carts (or drip tip if you got manual
batteries - drip tips not recommended on auto batteries) and use that setup to test eliquids. Cartomizers are not a good way to test eliquids because it trying to clean and dry cartos doesn't always work. Some people can do it and many can not.
Here is a Vapor4Life section of ECF. There is a handy video there for fixing the occasional dud carto and a simple guide. You can't post there until you have 5 non-spammed posts or replies in New members then wait about an hour.
