To you folks who are using high powered torches on bar/helmet mounts for cycling - what batteries are you using?. Specifically has anyone purchased additional 18650 type batteries for them?. I've got 2 x Ultrafire WF502B torches here which are simply amazing bar mounted with a couple of Twofish Lockblocks but the other day one of the batteries decided to give up the ghost. Now looking to purchase a couple of replacements but the different manufacturer options out there are numerous to say the least. Had a look on eBay and it's hard to tell what is good quality and what isn't.
My current batteries are 2600 mAh 3.7v Ultrafires, they came with the torches. What should I be looking for, does it follow that a higher mAh will be better?. I've asked this question in the Road Cycling thread in the Sports section of the boards too, hopefully someone who knows more about these things than I do can advise.
