    May be setting up headlight soon for use in winter. Concerned that gel cell may not do well when
    cold. Suggestions for dealing with this or other cheap types of batteries? I have some pretty fancy
    chargers from other hobbies. My lithium ion batteries are too small, unfortunately.

    Is there any way you could rig your light so that you can stash the batteries in your jacket? My
    climbing headlamp has a cord so that the batteries stay warm- I can hang it around my neck so it
    stays against my chest, or over my shoulder/neck so it stays in my armpit. Either way, it stays very
    warm, and my experience is that my headlamp lasts something like three times longer than a headlamp
    which has exposed batteries in frigid temps.

    if you feel handy, im betting you could cut the cord and splice in a longer cord so that it would
    reach your torso, and just sew a loop of nylon on to hold it around your neck. a little funky, i
    imagine, but it makes a huge difference if you can pull it off (though perhaps your battery pack is
    enormous. mine is only 6AAs)

    I don't have the light yet. I have thought about stashing the battery in my clothes and about
    insulating it. However, some types of batteries just don't have as much trouble with this, so I
    thought there might be solutions I wasn't aware of. Just need 4ah lithium ion! For my electric model
    plane that uses NiMH, a foam jacket keeps the batteries warm enough to run out their charge. But gel
    cells are cheap.

    You might consider the length of time outside as well. For a typical 15 minute one-way commute, a
    gel cell doesn't lose all that much heat, especially inside the standard neoprene wrapper.

    A two-hour mountian bike foray in real cold would of course be a different matter.

    I have my gel batteries in the garage (no heating). No problem even when -20 deg. C. Have a 1++
    hour commute and my 3.5 Ah 12 V battery have no problem in giving power to a 20 W halogen bulb
    during the ride.
