FTFY.

This is me vaping on it .........FTFY.
Old thread, old problem...
Possibly a new insight into what causes this issue though.
I got my grubby mitts on a db - 25r cells really wouldn't go in without much struggling - certainly far more pressure than I would ever like to put on a cell, and so much that I wouldn't give the door tabs long for this world.
So I took it apart for a lookie.
The battery contacts up at the top are the cause of the issue...
They are made from a bent piece of flat metal, much like every toy ever.
Because these contacts are wont to compress, there is a coil spring added inside for a little extra pressure and resilience.
The whole caboodle is soldered to the lower PCB - and herein lies the problem...
The assembly technicians are obviously of the mindset "more goop is more better" and they've thrown bucketloads if solder at the job.
What follows is a crap sketch, and a poor description...
View attachment 181554
Blue is flat spring
Orange is coil spring
Red is how much solder should be required
Green is how much of the flat spring should flex
However...
Grey is how much solder they've thrown at it
Purple is how much of the flat spring is available to flex due to overdoing the solder
So, the 'recommended' fix of hitting it just distorts the solder - it means the cells might fit, but it means there's still not as much flex as there should be, and it's still too stiff.
So, I filed out most of the excess solder and hey presto if it doesn't bloody work just fine and dandy.
So, that previously mentioned "inflexible battery contacts" thing both here and on the website sale page?
Liar, liar, pants on fire.
It's a blatant falsehood.
What this is, is a pure manufacturing defect caused by cack handed assembly and poor inspection processes.
For shame 3fvape, for shame.
You made up a load of bollocks to shift the blame onto the consumer. If only you weren't so stupid.
Of course, that's the warranty out the window....................
If anyone still wants one a UK supplier is doing them for £72, which is £27 cheaper than 3FVape.
