I have some of Gerbings S2 battery powered gloves and so far they have been warm enough for my winter riding in NC. The battery charge does not last very long though. I don't want to spend $80 for extra batteries if I can help it. Is it possible to rig a way to plug the gloves straight into motorcycle battery for long trips? I should have bought the hybrid gloves to begin with and I wouldn't have this problem but I'm trying to make do with what I have. Hopefully I'm not the only dumb one in this situation.

 

I just checked out the S2 gloves on Gerbing's website. According to the information for the S2's, the batteries should give you a MINIMUM of 2 hours at 100% output. If you're not seeing this kind of battery life, it might be worthwhile to contact Gerbing. Perhaps you have some defective batteries and they might replace them....can't hurt....
