As the board has common ground am I correct in thinking I can connect the battery neg to the 510 and then on to the ground pad rather than going to the B-?

I won't be relying on the enclosure as a part of the path, there will be continuity between the battery neg and the ground pad. I'll still be grounding the board via the mounting lugs.

i don't foresee any ill side effects from connecting batt - to your 510's ground. it's all common so...........

Check this out. Here is my Hotcig DX200 with a Subtank with a Ni200 0.09 ohm in the RBA Mini Plus.

[7Pv6lle] 

Here is the same Subtank running on a Lost Vape Triade.

[tlojhVR] 


Noticed the Triade is far much smoother? What is the difference? Well Daniel (DJLsb Vapes) said his DX200 uses the aluminum box for the 510 ground and the board ground instead of ground for the 510.

All I can say is to try it and it doesn't work really smooth, it would be easy to add the correct ground, right?

UPDATE: CB was typing while I was too. So I didn't see it until later.

billw50..........hes going to have a ground wire from the 510 to board. i think he wanted to know if he could ADD the battery negative wire to the 510's ground wire as well. so he should have proper grounding.

i agree though, having an actual 510 ground wire to the board is a plus and reassurance.

I thought I'd throw something up for comparison,  my DX200 not hitting temp DX200 not hitting temp.JPG
And hitting temp,

@  BillW50, what are you using for wire? It sure has a big change from cold to hot in resistance.

I know CB, but you have to add in the changes to inductance and capacitance using the box as the battery ground. It might work fine, but it could get squirrelly. It should be fine what Hotcig did too, but look at the difference.

@dwcraig1: As I stated, it is a Ni200 0.092 ohm coil. Same one on both mods.

Say I just saw your problem awhile back on one of mine. I solved it, but I don't recall what I did. I believe it was happening on a Crown RBA. What are you using for an atty?

Not sure what problem, refresh my memory.

Thanks for the comments guys.

To clarify I plan using the Cisco 510, the brass solder/capture ring has six holes, I plan on using 2 of them, one for the battery neg wire and one for the connection to ground pad. Heavy gauge wire will be used.
Although the enclosure is aluminium it's the ring that makes the connection. As I said I will still make sure the board is grounded via the 3 mounting lugs.

Bill, you made me look.  Granted these traces are from a DNA75 and a DNA200, but one, the DNA200, has the 510  connected to the board with a 12 gauge wire and the other, DNA75, get ground for the 510 from the body and gets board ground the same way.  Both traces show fairly smooth temperature regulation, no sharp peaks and valleys.

@scooby: It is worth a shot and it should work, but if there is a problem you will find out. It is definitely worth a shot.

Yes I see. Well I am planning on getting a second DX200 and see how that one pans out. Maybe there is a bad solder joint in mine.

Still not sure what you mean, maybe the low temp?
Oh, it's a Serpent
