WISMEC Reuleaux RX200 TC

@7sixtwo: You really can't trust the RX200 battery readings. I made a small log once the the bracket voltages are from a multimeter vs. the RX200 readings.

4.11, 4.26, 4.21 (4.20, 4.20, 4.20)
3.91, 3.95, 3.99 (3.91, 3.92, 3.92)
3.82, 3.86, 3.92 (3.83, 3.83, 3.83)
4.21, 4.21, 4.14 (4.21, 4.20, 4.20)

So is it battery no. 2 that is put under the most stress in the series? When checking the remaining voltage of the batts with the RX200, I've always noticed that one is a bit lower than the others, e.g. 3.87, 3.8, 3.84. I have the batts labelled 1-3 and rotate their positions in the tray every time I recharge em.

I've had no problems with ver 3.0, (came on the device), or ver 3.1. *knocks on wood*

Have you checked those voltages with a dmm? My rx shows the batteries as having different voltages but my dmm and charger show that they are actual at an identical charge level.

Good to know. I'd noticed the RX's readings changing slightly from one check to the next, (done within ~5 sec of each other), so I suspected as much. I've just been usin em as a guesstimation of exactly when I should recharge when the battery bar goes from ~60% to ~40% full. I usually recharge the set when they read ~3.6-~3.5V.

I have not. I don't own one. I thought that in a series, one of the batteries is put under more stress than the other two, but I guess that's unrelated to the discharge rate of each one. Right?

I'm no expert, but I think the batteries should be stressed equally, in an ideal situation. In reality the batteries aren't identical and the one with the highest internal resistance (if I remember correctly) will be stressed the most. It's dependent on the battery though, not the position of the battery in the stack.

...with the caveat that I might be totally wrong...

Back on 3.0 firmware and it's working perfectly again. All day so far no random changes and they're all .1 apart (in my charger exactly the same). Guess I'll not rush to install the newest firmware without reading into it. Crisis averted.

But now you can't vape at 250W, like the cloud-chuckingist of bros! How could you possibly be satisfied without that raw powah?!

Glad that going back to 3.0 fixed the issues you were havin.

Ideally all batteries should be discharged equally in series. Once they age it is possible that on or more may increase their internal resistances. Once this happens it will be strssed less than the others and the ones with lower internal resistances (most ideal condition) will have to bear the extra demand.

Another problem with an unmatched set is if the internal resistance of one battery is exceptionally high it can act as a load (think coil) to the entire circuit. It is highly inefficient for a battery to act as a load sucking current from the others. Not to mention the potential of excess heat generated if the current demand is high.

@atroph: I totally agree. But there are too many stories of one battery dropping extremely low (even youtube videos) which batteries when used in series can't be explained by normal means. The only explanation that would make sense is one of the taps to read the cell voltages is actually draining one of the cells on some RX200s.

 

[atroph]

?? Dunno.

So many variables and skill levels of said youtube stars.

I would venture to say that statistically speaking this is a great mod. 5, 10, or 50 negative reviews have very little influence on the amount that were sold. 50 bad out of, say, 10,000 is 99.5% success. Ask any business person or engineer and they would call that a win! We are not dealing with safety of flight or anything like that. It is a $40 mod afterall.

Increase the negative to 500 and you get 95% success. That is still pretty good for what it costs and what it does.

You want "high end" then get a DNA, although they (evolv) have had some issues of their own in the past.

It really sucks for the consumer who purchased a bad unit. Unfortunately the customer service for China mods is in the toilet and the best bet is to purchase from a B&M that you can physically visit and hope for an exchange. Problem with that is the B&M markup...

I agree with the spirit of your post but 50 fails out of 10,000 units is 99.5% success rate and 500 fails is 95% success rate.

Yup you are right. Sometimes the maths gets the better of me. fixed post.

Well mine started having problems with a few days left on the vendors 30 day warranty. Sitting idle most of the day and I picked it up to use and got atomizer too low and after that device too hot. Since device was cool at the time, no Bueno. After all the recommended fixes, switching batteries, coils etc... checking the 510 connection, it still goes into a coma, only to come alive and let me take 2 or 3 vapes and then relapsing back into a coma. I contacted the vendor and returned it for store credit. I doubt I will get another one and instead will look for a device that has a deeper 510 connection so that I can use all my tanks on it.
I am sure that most of you have a decent RX200 and don't have problems with it and hopefully that will continue for you. I enjoyed mine for 24 days and thought it a great mod, but after these problems I would rather move on and give something else a try.

Ok a couple things. I've had my rx200 for like 2 or 3 weeks now and I like it a lot. HUGE upgrade for me. I'm not thrilled that the paint around the bottom edge where it sits is wearing already but oh well.
Anyways I have a couple questions. When checking the battery voltages on the device what order do they go in? Is it left, right, then middle?
Also what is the maximum acceptable amount of variance between the 3? Right now mine are reading 3.88 3.89 3.86. To me a .03 maximum variance seems pretty good? When I first bought it I limped by a week or so by charging the batteries in the device until I got a charger and now that they're externally charged they're usually pretty close. I didn't like doing that.

Don't trust the battery voltage readings on the rx, they're really inaccurate. In most cases it'll show much more of a voltage difference than there actually is.

From memory, and I might be wrong, I believe that it's as follows as you look at it from the rear:

1 - Back left
2 - Front
3 - Back right

Someone correct me if I'm wrong.

Also- the device won't operate if the variance is greater than 0.3V.

Ok .3 volts. So yeah if one was 3.8 and another 4.1 Thad would be bad. I've never had much more variance than maybe .07 or so.

And in reality you probably don't have that much of a variance. See my earlier reply to you.

Has someone seen the "charger error" before? Found no real facts about it.
I have two rx200 and the the newer one with HW version 1.04 only a few weeks old started showing the "charger error" some days ago. Just have to wait a few minutes using an usb charger. Each rx200 got a brand new set of 25r only used usb charging and always cycled them after full load. The one with HW version 1.0 works fine. I tried different chargers, although they all work with the HW 1.0 one. And also checked if the battery set from the working one produces the same error - it does. Even tried firmware 3.00 instead of 3.10. Any tips what else I could try?

 

[BillW50]

@sdk: You mean it shows charging when it isn't connected to the USB? If so, yes I heard of that one before and connecting to the USB makes it stop right?
