    Yeah, I've looked at several of their products and they seem to be well built and relaible, and honestly at a good price point.

    Help with battery packs

    Looks like a winner to me. There is much to be said for buying quality batteries. Trust me. When it comes to a project, quality batteries make all the difference.

    Help with battery packs

    No, you're probably looking at the correct things lol. Good lithium cells are still ridiculously expensive. For the most common size, an 18650 (panasonic, sony, AW, etc), you could pay anywhere from $10-$20 for a single cell. However, they are worth their weight, as the brands I mentioned and at...

    Help with battery packs

    One thing that i noticed in the reviews was someone stated it was actually only 12000 mah instead of 15000, so that could change things a little. I'm no math expert anymore, been too many years since highschool lol

    Help with battery packs

    Reviews on amazon are none too nice as to the longevity of the pack. Common complaint seems to be the charging circuitry fails after a while...If it wasn't $55 I'd say go for it...If it were my money, I believe I would continue to look for a better option. My only other concern is what cells it...

    Help with battery packs

    Sounds like a good plan. the ground effect is actually very effective, and from some studies I have seen on emergency warning lights (Being a volunteer firefighter in NC), ground/ambient changes in lighting actually catch attention more than the light itself.

    Help with battery packs

    These notes are extremely true, and something I didn't think to mention. Normally around my area bicyclists are somewhat encouraged to have a slow flashing light. Not like a strobe light, but more like a 4-way hazard light on a car. Check local laws, and as Gryd3 said, don't make them too bright.

    Awesome. The flashing will extend the life of the battery pack to some extent, and as you already mentioned help to increase visibility.

    Help with battery packs

    I agree with Bob. Lithium would seem to be the way to go. Are you using these lights as "headlights" or just lights for riding at night so you have less chance of getting run over?

    If you "don't know how to make circuits" then all that info means absolutely nothing to you anyway. You gotta know the basics before anyone can help you out. Being there are a plenty of lessons and tutorials out there for those basics, they have helped you by advising you to do some Googling. I...
