Hi all.
I've only just found this site and not sure if this is the right one to post this in.
Im building a set of lights using the the ws2812b led strips. Its going to have 2x 4 meter 30led/meter and if I run it at full brightness and white it will require approx 14amps.
My long term plan is to run it from a 12volt battery and have that charge during the day by solar but for now might have to be a mains to 12 volt. I would do the mains to 12 so it will be easy to switch.
Where im stuck is on the psu for it and when using a battery what is required to cut the output when the voltage is low as not to kill the battery.
Ive looked at is a 12v to 5v STEP-DOWN BUCK CONVERTER

and a UBEC from the model world

Im not sure which would be better of if you guy and point me to something else. Im not planning of running it at full power so to be able to burst to 14amps or so and have 8-10amps normal may be ok.
Not seen anything for cutting the power yet though but know lead acids dont like to be over drained.
Thanks in advance
