Hello, everyone! Totally new here. Well, I'm going to buy a pair of 12 volt "eagle eye" LED for a medicine experiment, and I planned to connect them to either a rectangular 9 volt battery or 3 cylindrical 3.7 volt batteries. But now, these LEDs are meant to be connected to a 12 volt car...

Hi, i have a few question about lithium ion batteries i have an idea and for it, i need a battery that can generate 2880 watts. Is there such a battery that i can buy with that much power? if not, is it possible if i put 5/10/30/etc batteries in series to create it?

hello. i have a 24 volt motor that is 180 watt and 2600 rpm. i was wondering if i could hook up 36 volts to the motor to make it go faster?? would i ruin the motor or anything? should i not risk it??? thanks.
