Hello,
I am trying to power a 5v DC fan at maximum RPM, and I am using 3.7v lipo for space and weight savings. I have the circuit hooked up to a charging circuit (https://www.amazon.com/dp/B01LHD9D7E?ref=ppx_pop_mob_ap_share) and then to boost converter.
XL6009 DC DC boost converter module (https://www.amazon.com/dp/B07L64GJ42?ref=ppx_pop_mob_ap_share)
This circuit works well without load and I can adjust voltage from 5-25v. I can even setup a LED driver, and push a high forward voltage LED (5.5v) with no problems.
When i hook the 5v DC fan which is rated at 150mA the circuit shows 3v instead of the preset 5v. If I increase the voltage it simply outputs the same 3v. I can't imagine I'm drawing too much current but can't imagine what else is wrong. The fan works great if I plug it directly into a 5v source. I'm new with electronics and feel like I'm missing something simple.
