Lithium Batteries for bike lights

samdidgaf - Lithium Batteries for bike lights - A'ME heated bike grips


I still have a lot of these old Nokia batts. I soldered three into series (see my other warnings below!) and hooked it up to my hacked bike light (a 4 watt downlight globe inside the orginal bike light).

I got about 15 minutes use before it cut out - but I don't know how well the frankenbattery was charged. I'll give it a full charge and hook it up to my 30 dollar wattmeter and see.


Just this morning I read about the A'ME heated bike grips and thought it would be easy to make bike handle heaters with a few of these batteries, some resistance wire and a motor speed controller to regulate the current/temp.
Might give it a try.
