Hi I just registered with CPF, but I've been lurking around for the past year. I just bought a BC-10 and I can't believe how much of an upgrade it is from the Chinese flashlights I've been using for the past year. It's quite a difference and I am really enjoying the flashlight.
I was hoping I could have some experts help me out and tell me whether or not these batteries are safe for my new flashlight. I've been using the Tenergy RCR123a 3v 900mAh protected batteries with the chinese flashlights and they've worked fine, but after reading a thread reviewing the flashlight by Selfbuilt and the comments I'm not sure if these batteries are okay or whether or not they'll do long term damage. A lot of reviews on amazon have said that the battery puts out 4.2v at full charge. I'm not really sure how this affects the performance of the flashlight. Some help will definitely be appreciated.
