Some testing going on elsewhere inspired me to skip my crappy little PSU and do some testing with only batteries. I soldered a single SRP7030-3R3FM back onto the test PCB and tried both 2 and 3 cells that I had laying around on my bench. Resting voltage was around 7.9v and >12v.
Results were a little more encouraging this time around. Worst case w/ the 3s seemed to be about 8v peak w/ 11.6v input voltage.
8v peak at 15.7v input voltage (loaded) from 4s.
aaaaaaaaaaaand my modded HF meter is showing 15-20 amps output - clearly incorrect. If I “can’t see the forest for the trees” it’s because of stuff like this!
