Sigelei 213W TC Box Mod

I have this mod (Lord, I know this is an old post)

OK… So has anyone had the problem with it where you put fresh batteries in it, tighten the tank down and when you fire it the battery power level indication strip starts flashing?

It doesn’t do it all the time, just once in a while. I love this mod and I don;t want to replace it. I think it might have something to do with that little contact pin that must have a spring but I’m not sure.

Does anyone else have this problem?

Never a that problem of flashing unless the bateies are unbalanced it will go to a screen that says so
I have 2 213’s and just got a 213 plus love it also
I have many mods and these ad my favorites all day
