I have built a r/c car that runs on 2 30AH 12V DC deep cycle batteries. The motors are 24v motors that will each draw around 15A at full power. My motor controller can handle this, as well as reclaiming braking energy.
This is my way of saying that i have a 24v power system. Now my issue is that I want to run a 12v device on this 24v service. I do not want to have the hassle of another battery to maintain so i would like to power it off the main batteries. All the BECs and other converters that i have found only supply around 1 amp while the device i am looking at powering will take around 4-5A 12v DC. Does anyone know of a device that will do this.
