I use the PD's. They last for freekin ever and are perfect unless you get into low-resistance lunacy (below 1.5ohms and I highly discourage it).
I would put in a separate order for them and expect to wait 3 weeks to get them.
Do yourself a favor and do NOT cheap out on batteries or chargers. Right now, the absolute best charger on the market per dollar is the Xtar VP1 and Fasttech now sells them for an incredibly low price.

I can't stress this enough: Do not cheap out on batteries OR the charger.
There are other very good batteries out there too. These Panasonic come highly recommended by many who I would consider experts. They also have the raised button on the positive post... something you want for additional safety reasons.
If you want 18350's, look somewhere besides Fasttech, they don't sell any that I would put in my mouth and vape. You want the red Efest or AW IMR's (AW preferably, but the Efest is an excellent battery too). Both can be acquired from RTD vapor and they are an authorized AW reseller so you know they will not be fakes.
For a few bucks, it's worth springing for a fireproof bag too (
