Quote:On the PCB, I had 4 pads that I can place low-pass filters, currently I only placed one 100nF. I had been experimenting w/ placing all 4 caps, also w/ some higher values. They really don't make a difference in my testing.....

Examining the evidence, it is appearing that the bootloader induced memory corruption problem is the main concern. I had very reliably brick a unit just by jiggling the battery on its housing.

Hi Chris,
Thanks for the reply. I was unclear. I was just thinking more of something to basically "debounce" the battery, like a 10 microFarad capacitor. If the circuit can't see the intermittents from battery jiggle, then maybe you avoid the bootloaderish memory corruption, and life is okay.
