Before my 18650 lab testing, I am watching more videos on how others are doing.

Now I am going to do a stretch stretch test on the boost converter XL6009. The AliEx user guide seems not very clear, so I need to google the Chinese version to clarify.

New XTW6009 vs Old XL6009 Boost Converter:
So I googled for the XL6009 module user guide. I had a pleasant surprise! My XL6009 module is actually updated to XTW6009 with a wider input range of 3V ~ 32V!
In other words, my original conclusion that XL6009 not good for 3.7V Lipo cell input was wrong! This saves me much time of using my digital storage PSU (Riden RD6006) to verify XL6009 for oust of spec calibration/verification.

The OP's 12V 0.4A BLDC motor has the following spec:
I think it is similar to the following:
(1) Gdstime 7525 (75x50mm) DC12V 0.4A 2-pin Sleeve Bearing Brushless Sleeve Blower Cooling Fan
I think it is just an ordinary blower fan. So I will just get an common DC12V 2-pin computer cooling fan for testing.
GdsTime 7525 fan references:
(1) Gdstime 7525 (75x50mm) DC12V 0.4A 2-pin Sleeve Bearing Brushless Sleeve Blower Cooling Fan
(2) Gdstime 5015 50mm DC 24V 12V 5V 2Pin Ball/Sleeve Bearing Brushless Cooling Turbine Blower Fan 50mm x 15mm Blower Cooler Fan - AliExpress HK$66/2pcs
