Quote from: fazersharp on 01 December 2017, 10:58:34 amBeen looking into this a little more and came across home made heated inner gloves using something called kanthal wire but they started showing graphs and talking about ohlms law and stuff and the possibility of the battery melting.Can anyone with electronics expertise help me build some, the wire is in different gauges and my plan is to use 2500 rechargeable battery's 2 for each glove.I only need enough power to heat the second half of 8 fingers and only for 1 or max 2 hours and only on the backs of the fingers.Heated grips just wont do it for me as its only the fingers than get cold due to sh1t circulation, my winter gloves are good but after about 1/2 hour of riding the fingers start to get cold, my winter riding is a quick 1- 1 1/2 hour blast or until my fingers are too cold. so I only need to add extra heat for about 1 hour.I was out for about 3 hours yesterday in one of the coldest days of the autumn/winter so far but I was only pootling around from shop to shop in traffic and I was fine but that is not what I usually do when I am out and the main cold factor is wind chill which is why I am thinking of just heating the back of the fingers. I have looked into hand guards but they just wont fit.Word of caution, i’ve bought a pair of gloves from a bike show many years ago and they had a thinsulate inner glove in them.Problem i found was that the inner glove moved inside the outer glove on the throttle hand, so i found myself really having to grip the throttle to stop this happening which eventually became a nuisance and hard work.You don’t realise that a lot of throttle work is done with just the palm of the hand.I was lucky though to even get to try them, as when we got home my girlfrinds dog decided to chew the wrist part of one of them whilst hiding behind the couch.I was not impressed.

I have even thought of directly attached to my hands Goa'uld style.But what were you doing hiding behind the couch.
Yep AA, and thinking of 2 per glove - even if that would only give 1/2 hour of heat would be ok as it give me another 1/2 riding

With two Eneloop pro 2,500mA/H batteries in series per glove, you would get approx 1v*2= 2V average per glove and, say, with an average current of 2A (2,000mA), that would give you a duration of around 30 minutes and 2V*2A= 4W of average heating per glove.To get this, the resistance of the heating wire in each glove should be 2V/2A= 1 Ohm.Attached is the data sheet for an Eneloop pro 2,500mA/h NMH AA battery:
To get this, the resistance of the heating wire in each glove should be 2V/2A= 1 Ohm.
Thanks for all that.
would 4W be a good temp
But would the wire length also be a factor and if I have it going up my sleeve to an inside pocket then that will also be heating which I do not need, so would that section just be a normal wire with very little resistance so it does not heat up.
Don't know if these gloves are any use, but they are low cost and may be worth a try:https://www.ebay.co.uk/i/152552617838?chn=ps&var=451943275842&dispctrl=0&adgroupid=49522826521&rlsatarget=pla-378973156056&abcId=1128966&adtype=pla&merchantid=107424964&googleloc=1007219&device=c&campaignid=857333952&crdt=0

But because of crap circulation in the fingers they get cold, my hands - per-say do not get cold neither do my thumbs, so that is why I was thinking of inner glove and only to heat the fingers.

The electrical power just to heat your fingers may be less than to heat your whole hand, especially with an already well insulated glove.I didn't explain fully in the link to the eBay gloves (and they were only an example and may not be the optimum choice): I meant to say that you could probably use the electronics (batteries, charger, etc) maybe even unravel the heating element, for your own design heated glove liner, especially in view of the low cost. Of course, Dudefrude's suggestion of a ready-made inner heating glove is the way, unless you are keen on some experimentation and a custom approach.
