Spare batteries and lens adapters for Fuji XE-2?

[nightfly]

Got a used XE-2 recently and am preparing for a trip.

Need a spare battery and possibly a lens adapter to play with my Leica glass.

Any suggestions on batteries? Fuji or some 3rd party?

Lens adapters? The Fuji one is pretty pricey are there other alternatives that work well? Would rather probably just get another lens then sink money into the Fuji one since I'm on the fence about adapted lenses anyway.

i use 'promaster' batteries...as good as the oem. many use 'wasabi' also.
i tried a couple of adapters early on, i bought the cheap 15 buck ones and they worked ok for me.

I've got Wasabi Power, EforTek batteries and chargers, Patona batteries and an Oaproda slim travel charger that can plug into any USB charging device. One of the advantages of the Oaproda is that I can plug it directly into my Watson wall charger (for the x100s) and it charges from the power supplied to it by the Watson charger. It charges slightly slower than the straight into the wall style chargers but it's convenient to be able to charge both cameras batteries simultaneously. All are had affordably on Amazon and eBay.

For lens adapters, I have a K&F concept for my old m42 Helios and a cheap eBay brand for my Leica M mount lenses. I hear the Fuji one is good but not necessarily worth it unless you can find a good used price. The Hawk's helicoid is also supposed to be very good and worth a look (I'd probably spring for this before the Fuji), but priiiicey.
