Truce!!
Im not worried. I intentionally told him to get the olight instead of something like a meteor m43 because of all the safety features. The x7 has reverse polarity protection, low voltage protection, thermal protection. You can't even tighten the tail cap down if it isn't properly aligned. The kit batteries are protected Sanyo ga cells. Used to be Samsung 35e. Olight confirmed the switch. Pretty solid. The charger is definitely the weak link hence the post above. Won't cause any fires but killing your batteries due to overcharge isnt a desirable feature. I think this light will meet his needs. Checking a big back yard for coyotes and other predators at night.

First off, I apologize for being a bit snarky.
It's just that some of this is a bit more complicated for people not familiar with li-ion cells, chargers and lights that can really blast your eyes and do it in a fraction of a second and I know this from personal experience!
I was in the elevator with my GF and was fiddling with my EagleTac D25C Ti. clicky. I usually leave that light set to come on in low, since it has a memory function. Well, it had been tightened at the head, so it's on direct drive with my AW IMR 16340 and I quickly blasted my GF right smack in the eyes for an instant.
Oops. We walked around her area and she was seeing black spots for about eight minutes. Lesson learned. Imagine if I had hit her with your buddy's X7 Marauder?
Secondly, Olight was having some documented issues with their high drain cells bundled with the X7, whatever cells they were using. Turbo was non existent, or it lasted only a few seconds, so there's that issue, which may already be sorted out, but you can read the threads over on 'general discussion', or 'flashlights' for further understanding.
Lastly, nobody should be using li-ions (or even NiMH) cells and chargers without a digital multi-meter. They're almost mandatory for cross checking what the charger and cells are actually doing.
We take the above for granted, but making sure somebody knows what they're doing with their new charger and cells and actually getting some instruction prior to usage is both prudent and ultimately a safety practice. Flat cells can look similar from the front and the back and improperly inserting them into a charger with no reverse polarity protection can damage the charger, cells, both or heat up and possibly spark a fire, if not caught soon enough.
Anyhow, good luck to him, as that's a really nice light, evidently, but it's not a toy like a MagLite might be.
