Questions:
· Am I being too aggressive with my resistors. Current formula is at 35V/3A ~ 12 Ohms and 100 watts. I could set voltage at 33V output and go to 11 Ohms and 99Watts. Voltage max cannot go over 35 anyways. I am worried about losing too much in my resistors.
· Does my booster allow me to regulate current as well so I would not need resisters; it looks like more of a voltage regulator with a Max 10Amps?
· Should I put current drivers on each parallel circuit rather than resistors, that way if one blows I should be able to regulate current rather than blowing the whole string?
-> I am not that worried about blowing the whole thing because I have a breaker. And even if a blow the string I plan on having 3 others in the water to use as backup…
· For the switch panel I wasn't sure if I could put my own fuses in there at 9 amps?
· I am thinking that if two batteries have around 200 combined amp hours? Any suggestion on this to ensure we have enough juice to run these. Running all four in the current scheme would give us around 5 hours, I am thinking we may not be running all 4 all the time depending on what side we are hitting up.
Any suggestions on how to do this more effectively are welcomed. It seems like I am pushing the higher limits on all of this stuff with the current Schematic, but I want maximum output for the lights.
Diagram
A) Switch Panel ($37)
B) Driver ( $8)
C) Resistor (3X3 = $9)
D) LEDS (4*3 = $12)
I plan in running 4 of these circuits off the switch panel.
So that would be around $160 (exclude housing & wiring) for a Maximum 108,000 lumens
I am handling heat sync on a separate thread.
I am probably going to heat sync drive, resistors, and LEDs to an aluminum Square Bar/Plexi and have everything under water, so it will be water cooled.
