Hello everyone, this is my first post here. I'm pretty new to this whole thing but I've had an interest in it for a while. I just ordered myself a 1W 445nm Challenger from Sanwu. I'm confused about the whole battery situation and my research hasn't gotten me any information, only more questions. The site says that it takes a flat top 14450 battery, which when searched up doesn't give many useful results. I emailed Francis from Sanwu Lasers and I was told to look for a flat top 14500 battery on something like eBay or Amazon. Then there's the whole thing about cheap batteries being unsafe, varying mAh values, overcharging dangers with cheap chargers, protected and unprotected, button top and flat top, etc etc. Put simply, what's the safest and best bet on a battery for the Challenger laser from Sanwu? It has to ship to Canada, I strongly prefer free shipping, and I'd like a charger with overcharge protection to go along with that as well. Thanks a lot in advance!

Efest batteries are good. Do a search for Efest 14500 battery, in Google or even Ebay. You should be able to visually tell if it's a flat top. It just won't have the little bump on the + side.
