First off, great news, thanks for posting it! It sometimes takes some effort to sort it out, but as you just discovered it has it's advantages......
Bummer about the short 'grams'. It's usually pretty close in my experience with most concentrates since they fill the vial or container fairly completely so a short one in the box would stand out. One time I did get 3 that were not quite .6 grams, not the one the label said. Made for some pretty expensive wax. Next time I took the other two back still sealed to show them. They immediately apologized, said they'd mislabeled them and immediately put four real grams of the same stuff on the counter. I pushed one back and said, 'thanks, but I only got 3'. The 'guy' (turns out he was the manager....) pushed it back and said 'no, we're sorry....'. Yeah, he got more of my money. Still does.
Until then, the scale might be a good plan (although you don't know the empty weight). As Regan said, "Trust, but verify". Bet you didn't know Ronnie had a MMJ card did you? Must have been one of the first?
I doubt you could fry them that way, but anything is possible I guess. For sure you want the RCR123As to run a SV unit. While you wait (impatiently) for them why not send the lot (including the charger in fact) back to D9. They're usually very fast with replacements and that would give you a clean slate to start with.
There was some issue with adapters damaging the connectors mechanically. I believe it lead to an upgrade, it did on Omicron and I think I recall Persei having similar problems. My original Persei single head died but IIRC it was a straight electronic failure, quickly replaced (although now the s/n and logo are off of course....).
But that's my advice, sent it all to the shop, my bet is they'll send out a new unit, replacing both heads and the batteries and charger in the process.
Good luck.
