Started version 2 of the unofficial AA NiMh battery test today.
The last test with these fully charged 2450mHa batteries from Ikea lasted 21 hours. This time I added an “Icstation LM2577 Mico USB DC Voltage Regulator Step Up Boost Converter Power Supply Module 2V-24V to 5V-28V 2A (Pack of 4)” You just got to love the title of the stuff on Amazon.
Let’s see how long it will go this time. I am hoping for more than 24 hours. Let the countdown begin.
Test Parameters:
- Fully charged batteries
- Added Boost Converted and set it to 5 volts
- Connected to the USB power port on Pi for safety this time.
- Running my python script from the last test to record the current date and time to a file.
Funny note: I said in my Adam Savage voice when connecting the last wire, “AA NiHh battery test version 2, starting now!”
Results:
Start: 9:46 am
End 3:51 am
Total run time: 18 hours, 5 minutes
Not as good as without the booster.
