I bougth a 50W Led that is rated at 30-34 Vdc with a IF of 1500mA
I would like to use it to do video illumination powered by a battery array.
Is it better to pack batteries in parallel with lower voltage like the RC batts that are rated 3.6v 4700mAh and drain them with the DC-DC Stepper or with higher voltage batteries like the square 9v rated at 200mah
Instead of a DC-DC Stepper is it better to stack batteries to run this, like 4 x 9V 200mah series, and use a resistance to limit the current to the led?|
