The Xtar VP1 is a super smexy charger! New release! They aren't available everywhere yet. Very expensive for a 2 Bay tho.
When they come down in price a bit more, I'll be in the queue for one, for sure.
The VP1 will happily take FT 18350's with Out spacers. If you choose to buy one, let us know what you think.
If you prefer to wait for a price fall, I'd recommend the Nitecore Intelli i2. This charger does not require battery spacers for 18350's either.
