Reuleaux by Wismec

[dwcraig1]

I may someday correct these wires but at the wattage I use they are no problem, but for some folks they probably will be.

[VapingBad]

Has anyone measured them?
The min spec is
PVC 18 AWG 1.29 mm diam conductor
Silicone 20 AWG 1.02 mm diam conductor

ok battery analyser done for LG brown 300mah batteries

with the 3.09 cut off they came out at 28.97 WH

so 26100 mah  

however these did not display the fast roll off at lower voltages that lipos do.
and this was a test from their first charge.

I will be re running the test once they are charged with a 3.0 volt cut off as these look like they can handle it looking at the graphs in the analyser and the battery curve is much more linear than with Lipo.

I think it was john who said you could lower the soft cut off to 2.9 as the hard cut off is 2.85.

(don't quote me on that!)

I think this will get the reading and useful life  closer to the 3000mah 33WH useful capacity forgot to put the csv in lgbrown3000mah.rtf     change the .rtf to .csv and itshould work

[QUOTE=scooby]That was my face when I saw this VB. My first post, good to see you!

Out of interest and as I'm waiting on one of these, if the battery connection wires don't conform to the Evolv specs, as they don't by the looks of that image, what redress does a customer have with the vendor/manufacturer if any.

Good to see you m8, I was gutted when you left AAE-C hope you are keeping well.[/QUOTE]

I'm well. Sorry about that, my only regret was that I wouldn't get to see your craftsmanship at vapefest and get to show you 'Eclipse' but it was something I had to do for a number of reasons.

I know there's a lot of scaremongering on the web, but even without actual measurements just looking at the pics (there even seems to be an anomaly between the + & - ) it's plain to see that the battery wires are much thinner than they should be, especially compared to the output ones, this leads you to believe they don't meet the specs. Can someone take the measurements please to confirm this.

[xevape]

I would gut that box just to plop a lipo in it...I never understood triple 18650 for a DNA200.   Just doesn't make sense to me.   Those wires though.   That is pretty lame for such a nice looking box.

The wire 'looks' like 18 gauge silicone encased, the small wires are for cell monitoring and 1A charging to the Balancer. Voltage drop for such short lengths is negligible

Voltage drop for such short lengths is negligible <0.03V / lead. The most important 2 wires in the Mod, any, are the two output. Read the specs again and read the info printed on the wire. LOL you can use 20 gauge silicone wire for the battery.

If you look carefully the b- wire is not the same as the b+.. They're using the same wire for b- as they are for balancing..[/QUOTE]

I thought that they had disconnected the main -ve wire, but as you say the pics on photobucket show some skinnier wire for the -ve while the battery tray is being removed.

I'm not sure you can tell by looking at the pics that the wires are silicon!

All the wires are important for the efficient and safe operation of the device.

As Gm11 states and I mentioned earlier there is an anomaly between the + & - wire gauge.

it is obvious from the pics that something is amiss.

[dwcraig1]

I think they connected B- at another spot, the small diameter black wire seems to be for just balance.
Gee, if they are 18 gauge already, well I ordered some 18 gauge silicone wire this morning.

[Jaquith]

Silicone wires with flexible cores are more flexible and typically with more sheen than PVC counterparts. Wismec has a team of Engineers and they can read. I'm confident the Reuleaux is built to spec. Evolv has published their specs since day one. I'm confident they read them. If the Reuleaux is bad with bad wiring then prove it. My box wiring is overkill http://i.imgur.com/waQ0wmnh.jpg

[VapingBad]

As Flavoured pointed out on ECF the negative should be from the other end of the battery pack, maybe they are using the chassis.

[dwcraig1]

I my open mine later this day. I expect to find it has chassis ground too.

[dwcraig1]

There is obviously a problem with it as seen by the battery sag in the live view that I posted. I tested these batteries individually and got 36+ amps from the Mxjo's and 38+ amps from the Lg's pulsed with 0.1? load.

It just doesn't look like 16 gauge to me.
 

where are the balance leads? whats soldered on the four balance taps.

[dwcraig1]

Here is live view using same build but with a 900 mah lipo, note that the pack here is only charged to 12.1 volts where as the earlier test with the 18650' was @ 12.6 volts.

Now while I'd prefer to see 3 black and 1 red, maybe they chose the colors as they did to reduce production errors. Count them .. 4 .. see http://smg.photobucket.com/user/djs61/media/The%20Reuleaux/Wismec%20Reuleaux%2015.jpg.html

 

[Spector NS5 RD]

can you figure out where the balance leads are?

[VapingBad]

It only needs 2 balance wires, 4 is better but if they take 0 & 3 from the battery pads, need better photos, but you would expect to see a thin wire from each battery pad to the nearest balance pad and the 2 centre balance pads connected to the battery cradle.  I suspect that is what they have done plus taking the negative from the cradle to one of the screw points and common grounding to the chassis, but it is all conjecture from the photos.

draw me up a diagram kid. im pickin up what yer layin down, but  a diagram would make my night. thanks.

[dwcraig1]

I only see two balance wires, the third is B+.
I'm not counting the one that joins the cells.

ChunkyButt200 said:

Wow look for the little wires (2) red + (2) black = 4. Two from the top and 2 on the bottom .. all 4 balance are there and accounted for.

Yes on a 3S you need ALL 4 wires; positive and at the end of each negative:
 

[Identical ecig file and identical dual Ti/Kanthal Atty] Next 18650's sag (voltage drop) more than LiPo's. Here's a 2S DNA 200 (133W) with fully charged batteries (2) vs Reuleaux with 3S and nearly depleted (~10%) vs a 2000 mAh LiPo 60% vs 900 mAh LiPo fully charged:

Not very good, just lashed up in M$paint


This is not a recommendation, but it could be how the Reueaux is wired, just saying don't shot the messenger.

[/QUOTE]theres two red and one black, dunno where yer seein the fourth wire. but @vapingbad drew up a sweet diagram to help me understand. thanks @vapingbad.
