What batterys have a 12 or 24v, 3amp capabilities?
Im looking to get them attached to a battery so i can walk about with them. They got a box at the back which allows them to be powered with 12-24 Volts with an ampage of 3 to 3.5 a maximum power consumption or less. That's the information I've been given apart from their very robust and not very picky when it comes to power supply.
like i said i want to power them with a battery but don't know what battery or if i need to make any circuits.
