36V step down to 12V/20A for two pairs of LED’s
36V step down to 12V/20A for two pairs of LED’s
(OP)
I am not an electrical engineer but I took a few circuit classes in college 20 years ago đŸ˜‚. Before I burn up some very expensive LED’s can someone please check my work?
Here is the situation: I have a 36V/63Ah LifFePo deep cycle marine battery that I need to connect to four 12V/10A LED’s on my boat. I will put two LED’s on the port side and two on the starboard side. So I was thinking of splitting the leads off the battery and putting a voltage regulator to step down to 12V/20A for each side (port & starboard). Then each side will split again to a forward and aft LED.
Please see attached circuit diagram and let me know if you think this will work!
Thank you in advance!

Not sure about the Ah rating. I'm guessing the voltage will drop to 12 volts at about 36/12 x 1 hour = 3 hours.

From a 36V, 63Ah battery you should expect 3X the Ah at 12V, times the 0.96 efficiency for running your 40A of lights.

DC 36V/48V Step Down to 12V 20A 240W DC DC
No. But it does mean one 12Vout converter can only power 2 Lamps
A total power of 480W out load might need 530W input or so to the converter allowing just over 10% loss being conservative.
In theory, a new battery rated at 63Ah @ 36V can output 63*36= 2268 Watt-h or 530 W for just over 4h.

Here's some ideas that might be simpler.
1. You can run three LEDs in series and not use an inverter.
2. Install a 12V car battery and keep it charged. Use that for your LED circuits.
