Yep!
All penstyle
batteries will work in any penstyle charger (such as your Joye 302), even M201
batteries. [The M201 atomizer will not work on the other penstyles' batteries, but its battery is compatible with their attys ... and with their chargers.]
And penstyle batteries will work in the universal (push-in, rather than screw-in) chargers.
Tip: You obviously are a person of good taste (using penstyle atomizers).

However, the best skinny (i.e., non-mod)
battery is the Kr8 (280 mAh like the penstyle, but a
true 3.7V starting at 4.2V fully charged). You'll need a 901-to-801 adapter, but it's worth the extra
two and a half bucks (and quarter inch).
