Replacing worn out Wingsland S6 cells

Well I now have 2 S6 packs which are showing there age and much shorter flight times.

So time to replace the cells.

This time the cells I am using are Hyperion G6 1400Mah ones as I ordered the G7 pack I had before, but was sent a G6 one from Robotbirds in the UK

So this was the pack I received :-

A 4S pack, which means I have to carefully split the pack!

Balance of cells was around 3.8 per cell, but normally HV cells are around 3.87 per cell.

First off I charged the pack to storage which took 164mah to get the cells to 3.9 per cell which is what I would expect from HV cells at storage voltage.

 

Right now onto the tricky part!

First remove the blue shrink wrap.

and then the bit of plastic that goes around cells.

Then (CAREFULLY) cut the balance cables and remove from the pack.

Then what I did was to use a small grinder and cut the pcb like photo below

Also note cells are stuck together with very sticky tape and best way to seperate them is by using lighter fuel ,

squirt some down sides of cells and then after a min they will come apart much easier (AGAIN be careful, lighter fuel and lipos that can catch fire!!)

Then to make it easier after this I cut down the middle of solder where cells are to seperate the cells (Sorry I forgot to take photo of this)

But in photo below is where I cut which is marked in red.

Reason why I did it this way, was trying to unsolder the cells you need to apply too much heat. This is what I done before and I am concerned its damaging the cells, so if you are really carefull ginding and cutting is far less stressful on the cells, but you still have to be really careful not to slice through pack or short the cells with cutter.

Once all cells are loose you can unsolder what is left of the tabs and you should end up with something like this:-

2 of the 4 cells now almost ready to go into the S6 battery case.

Next solder 2 of the cells together making sure you connect postive to minus correctly!!!!

And attach the balance wire to the battery pcb.

A really big issuse is the case is quite easy to get apart as its not plastic welded, but held together with really small and flimsy clips that will almost certainly break when you get case apart.

On the case below the clips broke a long time back as I was testing different cells and the case looks far worse for wear by now 😉

Cells and battery pcb back in case.

Yes I marked the cells after reading with meter so I got it right.

The postive and neagtive is marked on the S6 battery pcb as B+ and B- (Triple check you got this right or you will blow the ESC and dc convertor on the main Wingsland S6 board!!!!) I know this as I done it once! And as you cant buy the esc board its a write off, unless you want to replace every esc fet and dc convertor chip which I had to do once.

So you must check and check again that the voltage you have on the pcb is correct at around 7.6v at storage and the small balance wire should be reading 1 around 3.8v if at storage from new.

After that put it in charger to make sure it charges and if you got it wrong, blow the charger and not the s6 😉

 

Then charged it up and then on next post will give results.

WARNING!!!!

Only try this is you are experienced in soldering and lipo batteries, you will 100% void any wingsland warranty and also void any warranty on the lipo pack, and so for most people I would strongly advise against doing this , and to get legal stuff out of the way if you do this mod and anything catches fire or burns down, or you destroy your S6 or charger its down to you as you have been warned!!

 

Best solution is some third party lipo maker like GiFi power would make better batteries , they make them for the Dobby and so why not the Wingsland S6??? I am sure they would sell a lot if they made some!!

Wingsland S6 Flash Light

Just got hold of one of these wingsland s6 Flash lights off Banggood

Clips on top of S6 and lines up with the data pins on top of the S6.

Quite neat that you can change the brightness settings in the app and also turn on strobe effect.

A drawback to all this is it will reduce the already short flight time of a S6 with the extra weight and what the light draws.

But apart from that a nice add on

Think out of all the clip on’s wingsland made for this, this one is the best.

The All-Around Obstacle Sensing & Avoidance module would have been a neat add on,

 

but Wingsland never released it and wont see anything now they given up on the S6.

Updating a Wingsland S6 with problems.

After trying out a different S6 camera firmware, my quad started to have issues connecting and staying connected and to start a fresh again I thought it be a good idea to update a fresh.

And as I not wrote anything before about doing a update and it may? help others having strange issues with there Wingsland S6.

What you need:-

Usb cable from pc to micro usb type which plugs in the S6 next to the sd card.

A Windows pc

Wingsland S6 updater util

Camera firmware

 

First follow instructions in the Wingsland S6 updater util link above from what you will also get the file from at the bottom of the page.

Now after about a few mins the updater will be done and S6 will have stopped flashing, so power off S6 by removing the usb lead.

Then run Wingsland S6 app on phone and it will tell you of a firmware update to install the lastest firmware version (because version in the Wingsland updater is a older one), so do this next.

Then download the camera firmware file above and unzip it and place the Wingsland.bin file from it onto the SD card.

Then put battery in S6 and power on and wait for a few mins until its finnished installing the camera firmware.

Then power off the S6 and take out the SD and delete the Wingsland.bin file from sd card and put it back in the craft.

Then once S6 powered back on , go to the camera settings on the app on phone and reset the camera settings.

I would also reformat the SD to cover all bases (Make sure you saved your videos first)

Hopefully all this might have helped.

Although doing this still will not cure the fact that at times when I start app there is no video and have to exit app and back in a few times. This only seems to happen on my iphone6 and iphone 5, the app on android dont seem to have this issue and so assume this is another bug.

Happy flying!

Wingsland S6 camera firmware S6X70807

I have added another Wingsland S6 Camera firmware – S6X70807 to the camera firmware downloads
There are a lot of issues for some with video freezing not showing up in app and dropping out etc.
Just maybe a different version might improve it for someone.
You can downgrade and if not happy you can upgrade back to latest version.
As always although I have tested this , you do it at your own risk .

Read the info at top of page of downloads please.

Wingsland S6 Camera Firmwares

**Update**
This version of the camera firmware caused me all sorts of problems with video locking up even more than normal and terrible lag etc.
So would not advise to try this unless you are curious and dont mind the risk!!

Wingsland S6 Range test

Another range test using R6 with S6 and got to 300 metres distance and could see it as a dot , and just as well I could see it, and using a android phone this time and video kept locking up and was lagging around 20 seconds! Most of this due to it being a old android phone I feel though.
Also on the Android version it shows a wifi strength signal icon top right and the ios version does not have this.
Think I see why its missing from ios version, it does nothing!!! Did not change strength in all the flight, so obviously another feature Winsgland never fininished to add to the list.
Wingsland should have released the sdk for this so maybe others could have made a better app for it!
Anyway, got out to 300 metres about 984 feet and video was still working , apart from locking up and the lag.
Then as I was at 50%, decided to bring it back.
Was flying out against the wind, so expected it to get back okay with tail wind.
But for a tiny quad, quite good distance and I think the max you can go with controller is 500 metres max which I think is hard coded into firmware, and to get far if possible it will be tricky to get back with short a short flight time we get on these.

Also the app seems far more stable on a apple phone vs android one.

The phone screen recording is not good quality as had to turn that down because this is a old phone and dont have the needed cpu power.
