Aloysius...I've encountered pre-filleds that were dried up also. Unfortunately, we don't know how old they are. I love V4L's pre-filleds but have had, on occasion, the same problem as you. I opened a ticket and got them replaced. I don't know anything about SmokeTip so I can't help you there. Does sound like they have an excellent battery warranty though. You don't see that kind of warranty anywhere.
Here is another tip for the flux's. Take the ceramic cup silicone cap off. It takes some fooling with to get it off but take your time and go slow. Avoid the coil at all cost. I use a tiny precision screwdriver to work it up and out (it can be a booger to get out). Once out, clip the wick opening a tad bigger with a sharp pair of scissors. This will allow the juice to wick faster to the coil.
