So been doing some scale offroading at night, and I got something similar to this from ebay http://www.ebay.com/itm/Cree-XM-L2-...726566?hash=item25899f93a6:g:kuoAAOSwyQtVwwCN and was wondering what would be the easiest way to power it from my main battery or something else, in order to get the best performance?
I have a 3 cell main battery for running the truck, so 11.1-12.6V from that, the radio runs off the speed controls 5V 3A BEC, and my servo runs off a 10A 7V seperate BEC. I tried some cool LED replacement bulbs for a car, that run on 12V so it was easy to just wire in. They dim under full throttle, since the speed control can pull up to 150A (with a different motor, not sure what this combo might pull but its probably alot lower) after the battery drops from being fully charged. I can add another battery, just to run these, but would need to know how big the battery would need to be in order to run a long time, say 4-5 hours max.
According to the specs on the LED I got it can take up to 4.2V and 3A?
