Config 1 has new AW18650s. Config 2 has new AW18490s. I have Heron v1s in all of them with the long Heron pin. I use the same v4 switch in both configurations - the taller insulator is used.
Edit:
I may need to watch this. I removed my Heron, took out the battery and noticed that the switch unscrewed without me unscrewing the negative post.
I have been installing as instructed in the video.
I have disassembled/reassembled again without the firing in the unlocked position (testing it on my desk at work right now) and things seem to be working again.
I am not sure what may have caused the switch housing to have worked itself loose but I will monitor and report back with my observations over the next couple of days.
Thanks, P, for the quick and helpful response as always[emoji3]
You're welcome and I am glad we found the cause of the issue
During assembling the locking ring has to be tightened on the switch housing as per video instructions, otherwise the negative post will be loose.
