I could use some help to make sure I'm doing things right. I'm making a LED Array with a 6volt rechargable battery.
LED Stats (What the guy on Ebay supplied me with, I hope they are right)
Voltage: 1.5V~1.6V
Color: Water clear
Angle: 15~30 degree
Current: 140mA,
Peak(pulse): 700mA
Power: 200mW (think that is peak, they seam to run at 90mW)
Size: 10mm
6v rechargable battery, seems to run around 6.4v
What I'm looking at doing is running 16 LEDs. 4 in a series, so I don't have to use resistors. Then run Four series of 4 LEDs to the battery.
I tested it with one set of 4, and got 1.55 volt across the LEDs.
Is there anything I'm missing? Or anything that looks funny here?
I'm not good at figuring out the power usage. The battery says it is 4.5AH
I tested one LED, and it was pulling 90mw. Am I corrent in assuming it will last a little over 3 hours?
