How to solder Lipo battery connectors Qs8 antispark 8mm (OSE)

This is very dangerous, this is not for kids, u must understand how electrical current works and have experience with lipo batteries. This is my way of de soldering a connector and soldering on a new connector. If you have any question's please feel free to comment. Thank you for watching

Thanks for the demonstration. I'm using these for my 50mph E-bike battery. 👍☯️

[@KiloWattRC]

No problem man. I just put a 2K watts vevor kit in my 6 year old SSR SRZ 800 and he's loving it at 35mph. Glad the video worked out for ya

[@richduperbash2966]

Great demo Brother 👊. Solding these big suckers for the first time right now and you boosted my confidence. Love the focus about safety. Nice skills and steady hands. May not be surgery, but kinda is when you need everything right 🍻

[@KiloWattRC]

Thanks for watching man. Also here is a updated video on doing them. Let me know if you have any questions and good luck man kzbin.info/www/bejne/bHOrZ4lsg9doj5o

[@richduperbash2966]

Truly appreciate it Brother 🙏

[@PatricksDIY]

Thanks for the Video, I think the lack of flux was my issue, this helped me out.

[@KiloWattRC]

Thanks for watching 👀. Yeah flux makes soldering life so easy.

[@tkostang]

When you’re doing the second wire (positive) I’d wrap that negative side with electrical tape. There’s not much room to wrap it but it’s possible. Nice video. Very impressive skills. I can’t solder lipos and stay that laid back…. Freaking anxiety

[@KiloWattRC]

Thanks for checking out the video. Yes you are right, safe is better then sorry

[@Convolutedtubules]

I was pretty spooked about doing this on my 14s lithium ion pack at 52v nominal and 280A maximum 🤯🔥🔥

[@KiloWattRC]

What are you using 14s battery for? If u don't mind me asking.

[@Convolutedtubules]

@@KiloWattRC I built it for my converted ebike. I also used it to power an induction furnace and hope to build an electric Mountain board for it too one day.

[@SOMNIOHM]

👍Good stuff!

[@KiloWattRC]

Thanks for watching man

[@dominicgonzales9057]

Man you made putting that cap on at the end easy! Most of the time when I put them on, one side of the tabs go in and the other side doesn't. I try to push it in and it gets mangled. Haha.

[@KiloWattRC]

It just takes patience

[@based_will]

Great tutorial man, thank you. Getting my MMX8S done up right today 👊

[@gaffle-411]

At 4:23 ladies and gents... not only should you add a little flux on that post, but you should ALSO lightly PRE-TIN THAT POST, THEN proceed with the rest of his steps. He didn't pre-tin it so it took longer for that wire to integrate/adhere with the solder and bind + he needed to get the iron touching the post AND wire for an even quicker melting point/bonding point. Also, your solder is a little too thin. A larger diameter solder would disperse easier and you'd spend less time and heat trying to get it melted in place. Lastly, you should have some electrical tape covering that red wire that had already been soldered for an extra safety step. If your soldering of that black wire would have come loose, it could have easily fallen down on the red one shorting things out. An electrical tape barrier would prevent such a mishap. Good post anyway...

[@KiloWattRC]

Yeah it all good. I tried my best giving the proper warnings of the dangers. I forgot to pre tin first lead its all good, did it on second lead. I wish could of made video super perfect but it happens. I have the thicker solder but I just like using the smaller solder for some reason. Thanks for watching man

[@KiloWattRC]

Alloy 60/40. I would definitely love to have lead free solder.

[@stevesocransky6341]

And in addition to the Pretin step in the plug as well as the wire . Wrap the gator clip teeth with 8mm silicone tube to protect the wire jacket

[@MRBRUSHLESS]

Awesome video very nice tutorial on soldering connectors great job thumbs up 👍

Thanks for stopping by my dude. More to come.

Thanx for the video, because I'm wanting to solder my own battery connections and wasn't quite sure how. NOT so hard,but ya gotta be careful not to short out the battery lol, battery fire is not good, lol. THANXSOMUCH ,and KEEP ON BASHING! FROM BARRIE ONTARIO CANADA 🇨🇦❤.

[@KiloWattRC]

Thanks for checking out the video. Yeah soldering battery leads takes patience and correct tools to me the job easy.

This is REALLLLLY good! Thank you !

[@KiloWattRC]

No worries my dude. Thanks for checking it out man

[@jimmyboy5881]

I’d really like to know what your temperature setting is on your iron in this video. You’re really making it look easy but I know it’s the small stuff that matters. And since I’m kinda new to this I can use all the help that’s offered. And thanks for the video BTW - very helpful to me !

[@KiloWattRC]

Thanks for watching. I had temp at 800F

[@3SonsRC]

​@@KiloWattRCmy temp only goes to 480....will that be OK?

[@hexidev]

​@@3SonsRC Most soldering irons wont work as the wattage is too low. Just check the wattage and everything above 100/150watt should work

[@gary6190]

Really enjoying your videos. Thank You.

[@KiloWattRC]

Thanks for watching man, I appreciate the support man

[@jeremyallen2917]

Hey DISHDOCTOR, I just stumbled across your video and it is very informative for soldering these connectors. We recently started using these on some of our builds. Have you ever experienced any issues with these connectors failing by getting very hot and the plastic ring on the inside melts? We've run into this a few times and can't pinpoint what is the cause. Thanks again for the great vid!

[@KiloWattRC]

Yeah when you run constant crazy amps the red insulator in female positive bullet melt to male positive bullet. QS10 connectors might be a better choice for your constant amp needs

[@njd879]

I'm actually going through the same problem with the xlx2 1100kv kraton 8s. I never considered qs10??

[@subradiant_music]

Great video. Also not a bad idea but I would tape the other lead when doing the final soldering just in case lol don't want any solder to drip off and condition both leads lmao

[@MikeStallone]

I do the same thing with taping the wire I’m not working with! Nice vid man, these connectors are amazing

[@KiloWattRC]

Yes man safety is important. Thanks for watching man

[@joseCalderon1976]

Many. That liquid really help doesn't it? I can solder, but I think that I'm sling its wrong because I'm not using the sponge or the liquid. Thanks for the video!

[@KiloWattRC]

Check out this video and let me know what you think 🤔 kzbin.info/www/bejne/bHOrZ4lsg9doj5o

[@nowEUCme]

I always heat shrink the connections before the cap goes on... without it gives me major anxiety

Great Video Bro

[@KiloWattRC]

Thanks for checking it out.

[@josephmorelli3191]

Great job! How do you avoid melting the connector. I have ruined so many connectors I don’t want to solder anymore.

[@KiloWattRC]

U want to only solder with male and female connectors connected. Have all materials needed in arms reach and know what you are grabbing. It takes some practice, but very manageable

[@DeRock401]

Qs8 hold so much heat. You can’t melt them unless you really overdo the heat. Also make sure to have male and female connected to act as. Heatsink.

[@xXYannuschXx]

These QS8 look great, but they are so freaking expensive. And the only stores that sell them to europe only sell them in pairs...

[@MrDeceptacon88]

Hi nice vid...have you ever had the solder melt and come off the connector while riding with high amps?

[@paulmryglod4802]

I just finished doing this. Blew up the connector after hooking it up. Bad solder job, too much heatsoak for too long.

[@hannibalshop-ups6598]

Thanks for sharing boss. That trick to get the cap locked in, sheer genius! Glad I saw this before destroying another one😂. So that glue you were using, is that pretty much flux?

[@KiloWattRC]

Thank-you for watching. Yes its is liquid flux

[@zeeek1]

If you just put some black tape on one connector you are far safer

[@andrewwhiting5526]

Nice video, what temperature do you have your soldering iron set at?

[@KiloWattRC]

I have a Weller 40 watt station. And I use #5 setting for temp. Not sure what the actual temp is.

[@dasboata1]

Nice job to help those out but the liquid flux is acid base & not supposed to use it on wire

[@KiloWattRC]

Completely non-corrosive liquid solder flux consisting of a solution of special rosin in alcohol. Contains no traces of acids or chlorides and is completely safe to use on even the most delicate electronic equipment. Part No. 10-4202 2 fl. oz. Bottle Part No. 10-4216 16 fl. oz.

[@fredvan1632]

What is the heat you set on your ion to do this solder?

[@KiloWattRC]

max temp 800F

[@vincevirina425]

can i use this even for 6s system or just 8s systems? and also...if i replace the esc, do i also need to use this on all my batteries? thank u

[@KiloWattRC]

Yes you can use 8mm qs8 antispark connectors on 6s they are rated for 200amps. Sadly all lipos will need the same connector upgrade. But its a upgrade that well with the hassle

[@joshherrman3201]

What do ya think of those connectors so far? I've been thinking about making the switch.

[@KiloWattRC]

I have them i have them on 22 lipos and 5 esc I couldn't be any more happy. Easy to solder, and for antispark feature is a luxury

[@SoleEpiphany]

Those connectors don’t mess around, what will you be using that batt in?

[@KiloWattRC]

I agree man. I'll use in X maxx, and arrma kraton 1/5.

[@briandicosmo3843]

Why cant you tin the wire and connector then use heat once to join them.

[@KiloWattRC]

That works

[@NepDouble07]

What do you mean misalign the holes? How would not having a connector plugged into it cause that?

[@KiloWattRC]

The heat from iron will soften the plastic in the connector causing the bullets to move or miss align in the connector. Making it hard to connect and disconnect. Have the connectors connected keeps the bullets aligned in both connectors making it easy to connect and disconnect

[@18ct]

Having that opposite connector plugged in also helps with heat dissipation whilst soldering. Especially if there's wires soldered in like in the video. Heat sink. Stops your plastic connector getting messed up. Thank you for the video. I'm about to solder 22s worth of li-po. Along with matching series harness. And parallel charging cables. As much as I like soldering. I'm not looking forward to it. Gonna take a few hrs. I spent £90 on QS8 connectors. Gonna be running 22s 10ah 25c tattu batteries at 150a peak. 92.4v @ 150a. 13,860w minus any voltage sag under load. 18.48 bhp on my bike.

You have to make a adapter.

Do you need flux for soldering?

[@KiloWattRC]

Yes flux is highly recommend, it makes the solder soak into the wiring.

“Male connector, female pins” Huh?

[@KiloWattRC]

The male connector uses femal pins vice versa female connector uses male pins

[@carpballet]

@@KiloWattRC Uhhh, nope. A male connector uses male pins (pins sticking out) and a female connector has female “pins” ( a hollowed out “pin” to receive the male pin)
