/diy/ - Do It Yourself

>>1483862
Just stopped at Wally World and they had these little power banks for $5. Logical thing for me to do would be to run the lights straight off the power bank so I avoid the whole unprotected 18650 thing and charging them off of a USB cord with alligator clips on the end.

But the mad scientist in me has another idea- I could rip out whatever protection circuitry is in the little power bank and attach that (plus the micro USB charging input) to the 18650 on the fixture.

Update- I just plugged this new power bank into the lights, it blinks the LEDs 3 times and shuts off. What the hell is that? This older square one runs them fine.
