I don't think 528 did anything wrong. If there was a short, putting it on a mech and firing it would make it quickly evident. If it wasn't a short, it would make it quickly evident. Regardless of which issue it was, putting it on an unregulated mod WOULD tell you the issue. I do this sometimes, and I'm an electrical fucking engineer, so I know how dangerous a short can be. No short (unless it's a literal dead short) is going to be SO bad it causes thermal runaway / damage of any kind in one second or less. Simply pressing the fire button for half a second and releasing would make it obvious if there was a short or not. Also, it's HARD for the RDA to be at fault, RDA's are SIMPLE as hell. You have negative post(s) milled into the deck, then a positive post(s) with an insulator around it and a copper pin running to the 510 positive pin on the mod. Unless there's a clear issue with said insulator, there's no way it can be a short issue on the RDA itself. I think 528 just told the guy to troubleshoot, that's it. People have become so fucking terrified of lithium batteries it's getting ridiculous. ANY even SLIGHTLY, POSSIBLY unsafe thing will have people roasting you at the stake, which is obviously what is happening here. #StopTheLithiumCult. People are turning battery safety into a religion. We can all color outside of the lines people, you just have to be as safe and as smart as you can be whilst doing it. Retail regulated mods can be picky and finicky, so I in no way fault 528 for suggesting this as a troubleshooting option. Also, the issue (jumping resistance) can probably be boiled down to one of three things. One, a bad 510 connection on the mod itself. Two, a loose/bad connection on the post-to-coil part of the build. Or three, a loose post (loose 510 pin, loose negative post, etc.). None of these three things are dangerous.. I think 528 would've saved themselves some grief if they just stopped posting after the first few comments, then deleting the comments definitely made it look worse. I don't think it's because they fucked up, more because they just wanted to separate themselves from the bullshit as much as they could at that point. All this is coming from me, someone who has openly and publicly stated on multiple occasions that he does not like 528 Customs or their mediocre products.
