I've tried some battery operated gloves by Five- great fit & pretty warm by themselves, and with a little heat they work well, but I have found the battery runs out of power at inconvenient moments - while it's still cold. It would be OK if the battery would last, say, 10 hours on low. Then you could charge them up again overnight. The last trip I used up one set of batteries, then one of the second set fritzed its connection & wouldn't work.
On with the Powerlet heated glove liners which connect to the bike and now more problem. Had the heated jacket liner on as well (also Powerlet), but didn't need the heat on that on. Riding all day with the jacket liner & glove liners on doesn't seem to affect the bike's battery at all (on either the V7C, the V7S, or the 1100 Sport)
Pete & some others have another brand of gloves which can use either batteries or a direct wire from the bike's battery - sound interesting.
It looks like the technology is advancing fast - so, watch this space, they seem to be getting better all the time.
You'd better hurry up & terst it out Ron, before the cold weather disappears completely. There was talk of a Tassie trip recently.
