Anyone tried DIY heated grips? This link Heated Motorcycle Grips | Shop the Best Heated Handlebar Grips Today! - Cycle Gear has them from $45 to $260. The cheapest $45 Trackside grip heaters is made with the same concept as these inexpensive ones from Aliexpress.
Shipping was 5x the price. I did a quick test. Ran them on a 2 A USB charger and measured 160 F surface temp with a thermocouple. Resistance is 7.5 to 8 ohms per heater. Will install them on my ebike by wrapping over it with self fusing silicone tape and see how well they work. No 5V on my ebike but have 12V. Will wire them in series and run it on 12V, get a little more heat. Hope they don't burn out.
