Pulling the trigger on XinTD C8 V4 XM-L2 T6 18650 from intl-outdoor, need to know where to buy Xtar+VP1 charger, batteries

Well thanks to Foy’s revieiws and everyone else here I’m ready to purchase bike lights, batteries, charger, and handlebar mounts. Also looking for a smaller helmet light with fast-helmet mount.

I plan on intl-outdoor for the XinTD C8 V4 XM-L2 T6 18650, need battery suggestions. Can this light use protected cells?

Where should I buy the Xtar+VP1 charger from?

How about a really lightweight AA or 18650 helmet light?

One of my boys and I are ready for some night paved trail and rural road riding and he’s been bugging me to get my butt out of the chair and back into the saddle.

md-lightsource has the VP1:
