Hi,

For the 18500s I mentioned earlier, not sure if this is good or bad, but I’ve put them in my Jetbeam i4 pro afterwards, and let that finish them off, and ended up at about 4.21V – 4.22V.

The specifications says 4.20 volt +/- 0.05 volt, i.e. the charge voltage must be between 4.15 volt and 4.25 volt.

The battery will end up slightly below that voltage, depending on age and termination current.

This means that both your result are perfectly fine.

I hope there will be a REV A-3 to fix the problem.
Did XTAR say anything about the bug?

Your picture only shows the led pcb, not the main pcb. Does it also say revision A2 on that?

When reported to them, they said that they will bring it up in their Weekly meetings and will be dealing with it.

Hi,

When you said “will bring it up”, what were you referring to by “it”?

I am quoting them verbatim from the email I sent to them. I guess it means that they will discuss it in their weekly meetings and will find a way to fix it in the next revision. That was about 2 weeks ago, they have not sent any updates on the progress.

We are dealing with the XP4 now, we should do more tests to make the new version better and best. Thanks for all feedback and please trust us.

Do you think that you’ll be able to do anything (improvements) with the already-purchased ones?
