/diy/ - Do It Yourself

HALP!!!

I still have this damn thing on my workbench. It’s the same shit that happened with the other one where I used a different power bank.

Still trying to power these LEDs off some Li-Ion batteries, want to use the chip out of a power bank so I can charge it via Micro USB input and have the battery protected.

Made a USB cable that goes to + and - alligator clips. The power bank was supposedly good for 1.0A, the light draws ~0.6A at full power. When I had the USB out plug to gator clips, it powered it fine. But I want to wire the output straight from the board so I have protection from draining the battery too much.

Used the regular switch, it flashes and shuts off, overcurrent protection I think. Used the dimmer switch and somewhere between 0.4A and 0.5A, it shuts off and I can’t run the lights at the full 0.6A. Two different power banks, both rated at 1.0A output, they both powered the light fine through the USB port. But when I rip the USB port off and try to solder straight to the board, I get the over current protection BS at around 0.5A.

What am I missing here?
