Wiring 3 50w LED Chips Off a 12v Battery
Those are meant to be driven by a constant current driver, so do not directly apply 12v to them. Instead select a 12v input constant current LED driver that can supply no more then 3.75A and has a voltage range that includes 12-14v. You will need a heatsink.
For longer lifespan and given that those look to be very cheap, I would stay around 2A or less.
