Please don't sell yourself short girl. This just happens to be a Unisex lifestyle, where both boys and girls are equally technically capable. You have demonstrated on more than one occasion you can play with the big boys LOL. We each have our areas of expertise and there is so much information out there it is impossible to acquire it all. I often coin the phrase that our daughter use to you when little; <<Sharing is nice>> You definitely have the bases down path, and only minor tweaking is required, if anything is required at all.
There has been some reported issues wrt battery spacers shorting out attys whehn changing batts if you are not careful, that is all.
I did learn something new today. That stacked CR2 protected batts will not fire a standard JoyE 510 atty. The protection circuit kicks in due to too much current draw. Ya, see, even someone with a technical background can be taught a thing or two. So please never sell yourself short.

There is much to learn and I have always enjoyed learning, more than passing on lessons learned.
