the leads were were a little long and heavy gauge wire so by me changing them out made for a better fit in the box IMO you might be able to get away without changing them
the one I linked fits fine not sure why the specs tab shows that size but the description tab is correct Dimensions: 106x35x41mm we have the same size box
I've found 2 of my SMOK RBA's have the insulator melted and cracked that was causing me issues with replay. SMOK has a new deck out for the TFV8 that is a clamp style and so far is working well
on the board did you jumper the the last connector pin 4 either back to 3 or to B+? do you see each cell voltage in device monitor? when I was ruining it in 3S I just jumped it to the B+
Are you using a 3S or a 4S? I've used a 3S for a week or so while waiting on the 4S to arrive just need to switch the config in Escribe but no issues at all for me.
None I did the all the calibrations ie the battery analyzer and case analyzer.
Replay doesn't seem to like my Steam Crave Titan no matter what build I use but using a Kylin it's working flawless.
