battery for heading pad

[rcs]

I'm looking for a 12V rechargeable battery to drive the 10cm X 5cm heating pad that you sell and was wondering if you carry it. I couldn't find something compact enough(ex: 4"X2"x1.5") for my application. I also need a charger for it. Could you point me in the right direction?

We do not have any 12v batteries or chargers. You can find these at Radio Shack, hobby shops or any of the on-line battery retailers.

This heating element is rated for 5-I2 V DC; I have a 14.5V 3800mAh rechargeable battery. Is it OK to drive it with this battery?

At that voltage the pad will be in danger of overheating. You could use that 14.5v battery to power two of the pads in series. That way, each pad would be getting about 7.25 volts, so they would both be operating at a safe level.

I realize the pad will get overheated, but could it damage it permanently? Can it handle it for say 15-30 mins?

We haven't tested it in those conditions. The resistive mesh is protected by a polyamide film. At some temperature, the adhesive for that will likely begin to degrade.
