Thanks for your help man, I was just making absolutely sure before I drop 30 bucks on a batt ya know. Also, whats a good resistance for carts for use on the pigcig? im using the turbo 808s from vapornine, not sure of the resistance. They seem to work very well on my 78 mm 808 batts. Any input on the subject of cart resistance?
These are resistances that I was given by the vendors when I emailed them a long time ago (late 2010). I don't know which manufacturers they get their cartos from or if things have changed since then.
LiteCig Premium Carto: 3 ohms
LiteCig LR Carto: 2 ohms
V4L WOW Carto: 2 - 2.2 ohms
V4L Cool Carto: 3.3 - 3.5 ohms
Vapor Kings Carto: 2.8 - 3.0 ohms
LeCig Carto: 2.4 ohms
LeCig Mega-Carto: 2.3 ohms
When I was using the PigCig, I eventually tried and stayed with the Boge 2.0Ω cartos. The Boges are very easy to find at a good price and is probably the most popular carto out there (for both 808 and 510 models).
Like dormouse said, you should use the PigCig charger. It's not that you can't use a standard 808 batt charger on the PigCig, it's just that it will take a really long time to charge it (standard 808 is around 280mah, PigCig is 650mah).
EDIT: I forgot to answer your question on which resistance carto to use. This is really a matter of personal preference. The best way to view it is in terms of wattage. Wattage is the amount of power and is a function of voltage and resistance (W = V
2/R). The higher the wattage, the hotter the vapor; the lower the wattage, the cooler the vapor. Keep in mind, a higher wattage may also tend to burn up certain juices, but this shouldn't be a problem with 3.7V and lower devices. I'm not sure of the resistance of vapornine cartos but assuming that it's 2.5Ω, with your 3.7V batt it comes out to 5.48 watts. Since the PigCig runs at 3.4V, you would need a 2.0-2.1Ω atty to get the same wattage.
... PigCig and slim KR808D-1 should be the same 3.7v.
I don't have a multimeter so I can't test this myself, but from what I have read (from DonDaBoom who is a very reliable source) the PigCig is 3.7V but only runs at 3.4V under load.
