I just saw this Infocus INL3148 laser projector that uses a color phosphor wheel with Red, Green & Blue segments. Of course the Blue segment may be clear, but the fact that it has Red & Green phosphors & has 5500 lumens, may mean higher power Laser diodes. Anyone seen any projectors with these...
I would also run the two bars in series (2.5 VDC each).
One thing I would caution you on, is that Red diodes are sensitive to turn-on and turn-off spikes from power supplies. So insure that the SMPS has a stable output.
You can regulate the 2.5 VDC @ 40 amps by adjusting the wire size...
Just received shipment of the new 10 amp discharge rated Sanyo 3500mah cells today.
Measured the Internal Resistance @ 26 milliohms .
A very good spec, since the previous 3400mah cell was ~50 milliohms.
Noticed that they have raised the positive terminal enough that they will work end-to-end in...
Analyzing Chargers do give you more information about your cells.
I use my Analyzer to give internal resistance levels for many different age cells.
The new Sanyo NCR18650 3500mah cells measured @ 30 milliohms on my analyser.
That is much better than the 3400mah cells . . .
I think you are misreading some of the Samsung cells.
The ICR18650-30B cells only have a 6 amp rating (the 30 refers to 3000mah).
High-current cells are only desired when you have current requirements over ~ 10 amps . . . since they are lower capacity.
The newest 3500mah Sanyo cells...
I used a 3 amp driver as customer wanted continuous operation capability.
From using lots of 18650 cells in stressful applications, the best method for matching cells is Internal Resistance with your cell analyzer/charger.
I have gone thru ~500 cells in various projects.
The original green NCR3400B Panasonic cells were rated @ 2C or 6.8 amps.
The brand new Sanyo cells are 3500mah, AND have a 10 amp rating.
That is a 47% increase in current rating and more capacity.
I also have some of the Samsung 25R cells with higher current ratings,
but much less capacity.
Having abused many 18650 cells in RC racing, I would caution everybody on using the pulse ratings on the cells tested. Every manufacturer would say DO NOT use them at those peak current levels, because of heat rise internally and possible venting/fire.
Maximum continuous current rating...
I see a problem with these drivers.
The SS14 Schottky diode in top photo is a 1 amp diode.
It will overheat and the solder will fail at 2 amps.
So if you have one, limit the duty cycle to about 30 seconds or so.
I also am not happy with GearBest .
I ordered a XL sweatshirt from them for a gift .
They didn't ship for a couple of weeks.
Then when I finally received it, they had taken a "Large",
and relabeled it as an "Extra Large".
