Sx350 - 510 Connectors, Ohm Readings And Other Stuff Needed?

[Chef Guest]

The SX350 chip comes pre-wired with a positive and negative power wire. I saw one guy soldered those wires directly onto the battery poles. I would not recommend you do that - that's crazy - and could have some real nasty consequences.

But at the end, you just need some way for the battery to sit in your mod, without moving around. People tend to just build a small housing directly onto the box they're building into.

For now my plan is just to buy the Aluminum box and then braze some divisions into an aluminum box - something that's tight fitting for the battery. Also, just going to use a cheap ego 510 connection for now and a old flashlight spring. Won't be sub-ohming this one or pushing it to 30Watts - will probably melt the spring if I'm seding 10Amps of current through it.

My bigger project will be building a mod from wood (Still looking for wood), with a Reo sub-ohm kit and bottom feeding capabilities.

See, I've got an old vamo pcb that I'm 2 play around with first just to get my head around the idea of what needs to be done.

But once that's done, I want to go the whole 9 yards with the sx350. Otherwise what's the point in having a chip that's capable of doing what it can do?

It would be like owning a Ferrari and driving around at 30 kph.

Saw some really nice walnut the other day but can't remember where! Will let you know when I track it down.

Agreed - that's why the I've decided on a two step plan - something quick and nasty now, but I can't push it (more like putting a Ferrari engine into a Volksie)

And then take my time to make something nice instead of rushing it.

I have one or two of the old Reo hot springs (before the gold plated ones) around if that could help.

Wow, thanks for the offer. Those are still pretty decent springs - see people pushed them to 8Amps without any problems. Wouldn't mind getting my hands on one of them if possible.

Would be greatly appreciated @Matthee

Long term though what would be the best option? More imports?

PM me your names, postal addresses and cell numbers and shall post. Long term option - I am a total untech, so a waste asking me, unfortunately.

Maybe @johan can advise?

For longterm the one @Matthee send you is more than sufficient, after all you are already limited to 35W by the SX350

I want to order a repair kit from Reosmods - but that's mainly because of the centre pin with a hole in it, the bottle and the tube as I want to build a bottom feeding mod with the SX350.

The better battery contacts that come with the kit are a bonus, and probably not needed - and the spring from @Mathee would most probably be all you need. The only time that spring seems to fail is if you short it - and the SX350 comes with protection for that as well.

Oh, now I understand your question. Thought you meant long term is the sense of the whole project. Yes, @johan is correct. Those springs can take 0.4 ohms (44 W) with relative ease.

But now if for eg you're using a sony vtc5 30A cont. discharge? Cos @Matthee said that it can handle 8 Amps? Sorry if I sound stupid. don't know that much about this stuff...

 

[Chef Guest]

Ok. And if one were to go super low? Like 0.2 - 0.15 Ohms?

It will start sagging and eventually give out. But, if I understand correctly, the 35 W limit on the chip will in any event prevent you from going that low. Around 0.55 ohms will probably be the lowest you can go.

The SX350 module will go into protection mode when i.e you have a short in your atomizer. So irrespective if you have a 100A battery, it will not draw more than 35W/4.2V = 8.33A. If the SX350 should go faulty and cause a short, the spring (as provided my Matthee) will collapse within a couple of seconds and long before the battery starts to gets hot. Hope it answers your concern.

PS. I'm really bad at explaining.

@Matthee is correct, with SX350 you can't go lower than 0.5 Ohm coils - lower than that and the SX350 will go in protection mode.

Well, cannot be that bad - I understood that.

instead of a super spring, what about a folded piece of coppe plating that has a spring in the middle? that way the current still zaps through the copper, and the battery just compresses the spring?

 

[Chef Guest]

@johan - Thanks alot for the clarification. My brain is swelling with the influx of new knowledge that I'm getting from you guys!

 

[soonkia]

Will have to wait for the board and start doing tests before I decide on final design - very difficult to really determine anything without all the components needed - and merely working off a pretty rough spec sheet

 

[Spyker]

Here is the file showing dimensions

Here are 2 more I found, the first one is the wiring diagram and the other one shows the dimensions.

I was thinking of using something like this for the 18650 battery. Upgrade the leads to something a bit more beefier and I reckon it should work!

But where did you get it?

Slowtech. Already ordered.
