Hi Texas_Ace,
First of all, I do not have the skill and tools to build by myself a driver like the one you have designed.
About the size of the driver, it is not an issue, I already made some lights based on 4 Cree XML, and I use some metallic boxes (20 cm x 10 cm x 5 cm to give you an idea) to put heat sinks, fans, and have enough space to do nice wiring. It allows me also to use large carclo optics of 26.5 mm diameter.
About the batteries, I do not want to use 18650, I have already a ton of different Lipo batteries (from 3S to 6S, up to 8000 mAh) that I used to fly my RC helicopters and drones.
My previous lights work fine, no overheat issue, and I drive the LEDs at 3 Amps each time for several hours.
Why I am interested by this device, it is just the nice display to see live the parameters (current, voltage, power, Vin…), I like this. And because it is all integrated, no exta effort to do to connect by myself a voltage/current LCD display.
May be I can use the DPS5005 instead, it will take less space.
I do not want to ignore your advice, I’m here to exchange with skilled people, so I carrefully take in consideration your message, and now I don’t know what to do…
Many thanks to take time to read me and answer, I really appreciate.
I hope my English is not too bad…
Regards,
Richard.
