I have an old Pentagon Light L2 that takes 2 cr123 batteries. It has 6volt printed on the side. I'm having a hard time finding info on it. I've finally exhausted my stash of batteries and am not willing to buy more expensive, disposable batteries. The light works perfectly and suits my needs. It was issued to me on deployment so I'm kind of fond of it as well. I'm trying to find a suitable rechargeable replacement for the cr123's. I'm pretty sure two 3.7v (4.2v fully charged) batteries would fry the thing. I found Soshine 3v rcr123's at orbtronic, but the tests I found said to not run them in series. Any help would be great. Thanks.
