Apollo Reliant 60W - TC with TCR adjustment, including Stainless Steel support

[cigatron]

@cigatron I don't have a Evic so can't comment on that however I've over shot the SXminiM's "0.3 ohm max TC" by 3-4x without problems in Ti mode so using that as an example, I think other mod's "max ohms in TC mode" might very well be bogus as well.

A quick look at the Reliant website and manual say nothing about the maximum resistance in TC mode. 2ohms seems to be working for me here. I do have another Lemo2 clone that I may play with later today - maybe see if I can get a 2.5-3.0ohm coil to TC.

Others have commented on the SX m-class having a "soft" max res function. Violating the max res on those mods turns down power or something, but stays in tc mode. The Evic has a hard cutoff at 1 ohm and will jump out of tc mode and into vw mode if violated.

Looking forward to your high ohms testing with the reliant. If it can handle 3 ohms max res in tc that would open a lot of doors to alternative wire types and help with tc accuracy and precision.

Humm.... I left the Ti (0.35ohm) tank mounted last night when I put the mod on the USB charger and no "new coil y/n?" this AM. (I have not found a way to 'power down' the device, you can lock it but it appears to be always on.)

Maybe it does it with x% resistance change?

 

[USMCotaku]

I'm of a similar mind. Ti is performing fine for me, and I have a preset for it.
Besides tinkering with new wire, what's the advantage to SS?

One of the advantages is you can safely run it on a non TC mod, so no worrying about "what coil is in this tank?" [emoji14]

So is this an SXK board with some firmware tweaks?

Yes and no.
The board is made by sxk, with design input from Apollo that go beyond firmware tweaks.

I believe the maximum voltage the mods can generate limits the maximum resistance that can be used at maximum wattage/joules. Considering for most of the builds that I use <30W or even <20W or even 15W is plenty enough power to reach my set point in <1sec I'm thinking that at say 25W (for example) the maximum resistance is double what YiHi specifies. Other mods may just assume that a >'x' ohm coil when fully heated would require more voltage than the mod's chip is able to produce, (limiting available power) and automatically kick you out of TC mode when it detects a coil >='x'.

While the Apollo Reliant does not list the upper resistance limit, there is a limit to the boost voltage the chip can generate. It might be interesting to see if the Reliant starts to auto-adjust the wattage setting downwards (like it does when the battery voltage drops).

Yesterday I was having issues with winding a large 32awg Ti coil and ended up using 28awg and getting a much lower target resistance. While in the middle of this my almost exactly 3mo old SXminiM decided that it would claim any tank mounted has a resistance of <0.050 ohms and no longer fires. So I'm down to one reliable single 18650 mod until I get the SX fixed/repaired or replaced with something else.

(sigh)

Far beyond tweaks such as..... I understand it s a different UI. Is the TCR adjustment comparable to an SXK.

He has an SXK Nebula and a Reliant, the temperature control on the Reliant is more accurate and smoother. The Reliant also has mech mode, no other SXK has this feature. It isn't just an SXK in new clothes.

And yes the interface is refined.

Oooh, that sucks. Still within warranty I hope.

Off topic for this thread but that high price tag on those things does buy the user something rarely seen in the industry - 1 year warranty. The vendor I purchased it from is trying to figure out how to do it has they never had one returned before. Here's hoping that they honor it and don't find some excuse to say I abused the thing.

I'm really starting to dig the flat spot where it says "Reliant" as that is where I park the mod in between use - let it sit on its back - screen up.

Maybe it does it with x% resistance change?

I often wonder if that's the case with the Evic as well; x% res change causes new coil/same coil message. All I know so far is with a .19 ohm coil the res has to change a minimum of .02 ohms to display the message. When my 430ss arrives my new builds will be twisted .35 ohms. Then I'll know whether it's a x% res change or a fixed .02 res change that triggers the message.

I will try to remember to resend it tomorrow, it's apparent that it got lost since it's been 7 days ago I sent it out.

No hurry 54, maybe it'll show up tomorrow.

Reliant - 1 week later....

• I have not quite nailed it down but it seems like a resistance change of 0.2 ohms is enough for it to ask NCSC
• After being on the charger overnight I got asked the question and I said YES. After answering the question (why don't they display the resistance while asking the question?) I found that my ~2.0-2.1 ohm coil had dropped to ~1.9 ohms and now I had a weak/lame vape. I hit on it a few times and then dismounted the tank and purposely remounted it "warm" and when I got the NCSC question again I again answered YES and got the resistance locked in at 2.1ohms - almost perfect and a great vape!
• Thankfully the Reliant will ask the user rather than autoadjust the resistance down from the initial setting (like many other mods do). Funny it seems like other mod owners are attempting (by freezing) to get the lowest reading possible so the mod does not 'auto correct' it to a lower value later.

I'm liking this mod.

Off topic: The other half shipped off my SXminiM to the vendor I purchased it from today. I'll know next week if they are going to replace it or not. While the "M Series" is still listed on their site for sale they told me that they could not get any more from YiHi and any replacement will likely be another brand.

I thought it was on a timer but it isn't, I had it not ask new atomizer question after sitting all night.

It's definitely due to ambient temperature changes over time causing the resistance to vary.

I agree, a mod takes a lot longer to cool than an atty, greater enthalpy. After vaping for a while it can take hours for the mod to cool to 20°c, especially if ambient temp is close to 20°c. Seems like my evic tc mods refine res at the very instant they reach 20°c. That can mean overnight at 20°c room temp or less than 15min in a cold vehicle.

 

[GeorgeS]

I'm having an issue with logic and the mods that 'refine' the resistance of the coils. Correct me if I'm wrong but in almost all cases the 'refinement' results in a pathetic vape.

The "logic problem" then is why do many TC mod users assume that the mod's themselves are able to read ambient temperature when that exact feature (if it existed) is what might be used to correct any resistance readings.

The way I look at it is if the mod compared the ambient temperature and the resistance of the coil between uses it would be fairly easy to determine that a drop in resistance was because a drop in ambient temperature (and a rise in resistance may be related to a rise in ambient temperature) and the registered resistance of the coil should remain the same. However if the ambient temperature dropped and the resistance of the coil remained the same or higher, then it may ask if a new coil was mounted as it would expect the resistance of the coil to drop with the ambient temperature.

The Reliant appears to ask if a new coil is being used if the resistance changes by some predetermined margin OR if it the coil is just disconnected for a few seconds. On other TC mods (such as the iStick TC40) even when the TC is supposedly "locked" if the mod senses a lower coil resistance it will use the new lower resistance to calculate further coil firing.

 

[f1vefour]

If the device could read ambient temperature and compare it to the previous resistance this would be perfect, the new atomizer question works fine just in a manual way.

Now that I know it is due to temperature changes I like the feature, I do wish I could turn it off and have automatic correction based on temperature instead.

With both methods included it would be fool proof.

Ideally it could use two temperature readings on screen, current temp and last temp when last fired for automatic mode.

And in manual mode say "AT (ambient temperature) Change of 4°F - New Coil Up/Previous Down.

I mean this is ideally, it could be implemented in different ways.

 

[jazzvaper]

^^^^^ Or, it could ask whether you changed location. The Arctic? Sub-Saharan?

 

[f1vefour]

I swear it seems like the Reliant has a boost feature, it gets down to reach temperature.

What do you mean by that? I don't get it...

In any case the "new coil or old coil" is not annoying me. It comes up mainly after you sleep at night and never during the day unless I switch atomizer. I can definitely live with it.
