I got the light Saturday. I screwed up. Evidently I ordered the SAR version. The headband is rubberized, made to mount on a hard hat. I called Fenix today and they emailed me a shipping label to return it. They don't do exchanges, so they said just order the correct one after they credit me back.
So, I just ordered the correct version tonight, in anticipation of the refund.
I quickly tried out the " wrong " one last night, holy cow like the headlights on my new GMC! I'm looking forward to navigating with it.
@tod osier. The battery is indeed a sealed battery pack. I forgot to inquire how much a new one would cost. I'm sure it's not cheap, but I'm expecting more than a few years life out of the pack
* I just watched a YouTube video showing the HP30R battery pack fits this unit too. The HP30R pack opens up and holds 2 replaceable batteries. The HP30R pack even clips on the HP35R headband *
