I'm thinking about adding some flashing LED's to my child's ride on vehicle (Power Wheels). I'm looking at something like this by Sho Me..
It says each LED unit draws 0.05 amps and is powered by 12VDC and there is a controller that I would have to buy too. I'm hoping I can just use a bunch of alkaline batteries in series (by finding something at RadioShack to hold them) but I'm not sure if alkaline batteries have the amperage capacity to provide constant 12VDC for any length of time - especially for four of these LED units. I couldn't find the mAh rating of Duracell batteries on their site - can anyone give me an idea of the typical mAh capacity of a battery and whether they think four of these LED units at 0.05 mA each will work with a regular battery pack without having to go to a 12VDC lead acid rechargeable battery (such as those used to actually power the electric ride on vehicle). Note, many owners of these vehicles actually tap into the vehicle battery system, but I don't want to do this. Thanks!
