You can use your own protected cells i think, at least somethingThis little light is awesome! However, there are a couple of things I'd like to bring to everyones attention:
1. The included battery is not protected.
2. The built in charging circuit charges to 4.3 volts before stopping.
3. There does not appear to be a low voltage cutoff at a reasonable voltage. I stopped mine at 2.4 volts when doing a full drain test.
4. The lens is plastic. It scratches VERY EASILY. Be careful!
5. The interface is awkward. Very Klarus RS1a esque.
Aside from that, it's a hilariously bright but tiny light. Blows everyones mind that sees it. The tint is amazing. I don't have a single cool white light that has a tint this nice. The beam is great! Much cleaner than my only other triple (Nichia 219 triple) and floodier.
I think it's a good buy under 60 bucks.
plastic lens is ok, the olight SR mini used plastic lenses as well.
