BLF A6 FET+7135 Light Troubleshooting and Mod thread

So ā€” itā€™s a tangent, but if anyone has suggestions about what would be a good host for a triple 219c ā€” please start a thread about that.
Something with a whole lot of extra heat sinking, I guess?

I have been using one of the Mtnelectronics FET +7135 drivers in a triple with no apparent issues. The only difference is that I am using an 18350 tube, so I only draw 9A or so maxā€¦. With the 219C it gets hot, but I do not seem to have the other timing related issues.

On the other hand, I also built a 18350 219C triple with a 3A Qlite, still a good amountof light, and nowhere near as much heatā€¦

Perhaps a X6 with a copper heat sink? Or did you mean a tube light?

just hoping someone will start a thread for it elsewhere, this oneā€™s not the place to go off track

lol, then why not just start one silly.

Now that I know what I know. I may go ahead and order the convoy s2 host that goes along with the spacer I already have. The spacer really seems an important factor. Chopping it to fit in the a6 seems like the wrong move. (But I may get impatient and try to finalize this thing. I want some beam shots!) :wink: RMM already builds an s3 tube triple so it must be working well for him.

And thanks for your help Tom E! The only thing I have any business doing is soldering - and even that has been a learning curve! I really didnā€™t do a lot of research before I started modding this light. I emailed RMM one time but really didnā€™t read many threads on triples before starting.

EDIT:

Hi have the longer copper spacer (for the S2) and put it in a S8 (which used the same pill and reflector as the S2). It seems to handle the heat much better than the S2+ spacer I used for the BLF A6 triple I madeā€¦much better. The BLF A6 triple got hot much faster than the S8.

QUESTION! Does the shorty tube fit a protected 18350 cell? KeepPower P1835C 18350 900mAh geschĆ¼tzte wiederaufladbare Li-Ion Batterie Sale - Banggood Deutschland sold out-arrival notice-arrival notice

Nope!

I have tested that particular cell and it is too long for the short tube.

Are you able to recommend me a capable battery for the shorty? I wan max capacity and max discharge. I dun care if it protected or not! Thanks! :slight_smile:

KeepPower (unprotected), Efest, NiteCore and Xtar are all good choices.

These are 18350 cells right? Not 16340?

Yes, all 18350.

THANKS! :smiley:

Thanks! So youā€™re saying that you built an s8 triple or you used the spacer from one? I wonder what the difference is.

Or did you mean you used the S2 spacer (the long one ā€” not the short S2+ spacer) and put it that spacer in a Convoy S8?

Hi guys, Iā€™m sorry I was not clear. I used the longer spacer for the S2 and put it in the S8 host. The S2 and S8 used the same reflector and pill.

The convoy must be better at shedding heat. Must be the pill. It looks more heavy duty than the shelf in the a6. Thanks again tristanxoxo!

If a light gets hot faster at the same drive current as another with a similar mass pill it means itā€™s conducting heat better not worse.
