2025.05.16 test five Powkey s60 medium wallets:


I was expecting sun around noon but it didn't happen. But then it got unexpectedly sunny around 1pm, with tiny
clouds occasionally blocking the sun. Good enough for me to run out with my gear and test the original and four
new Powkey s60 wallets. I wanted to see how they performed individually (to see if I got any duds) and also to
see how they would work when connected in parallel.

This was also a good opportunity to compare the performance of my small CPY FLA controller against my
small 150w and 300w LIFE controllers. I brought out my ancient "load tester" (light bulb box) to pull down
on the batteries while the controller tried to recharge them. (I still have yet to come up with a static load to
test panels with)

Sadly, the light box failed after running at 24 amps for several minutes. I haven't opened the box to review
the carnage, but I'm expecting the relay and possibly a few lights to be in pieces. I need to make a new box
with the big resistors so I can test more reliably. I suppose I could drag my electronic load out, but it's also
somewhat limited in power dissipation, and requires AC power. (the display is also basically impossible to
read in full sun)
