Just had a bit of an oopsie while I was zooming around my backyard and when i went to check on the drone i noticed a few wires sticking out of my battery but i couldn’t and still can’t figure out where they came from and where they go. It’s an ovonic 6s lipo if that helps. Thank you!
#Where do these wires go?

you broke the balance plug
the wires are from the balance plug
the wires should be in the balance plug
if they're not, they'll spark
While repairing this is not impossible, it is not something that I would recommend if you don't already know exactly how each of those wires is connected. Replacing balance plugs is a delicate operation because of how careful you have to be not to short the Lipo cells together in the process
@little cedar ehh, I think that in many cases it's actually quite easy
If you or I were the one doing it, I'd agree
Just make sure to tape pins up if you have multiple out, and the just transfer them over one by one to a new housing, replacing any broken pins with new ones by splicing them on from a sacrificial extension
Everybody sucks at it the first time.
I'm a bit worried that you don't know where those wires came from, because they came from one of the two plugs that have to always both be connected during charging.
When i looked into the housing all the holes already have a wire in them, which is why I’m confused to where they go
6S lipos have a 7-wire balance plug. You broke two pins completely off the plug.
Oh wait yeah, I just noticed part of the housing is missing
that might be a little bit of the issue
it must’ve snapped off with the crash i guess l, Don’t know how i didn’t notice it earlier
first of all
tape the loose pins up
if they short out, bad stuff will happen.
Afterwards, order some 6S balance extensions if you don't have them yet.
Like put electrical tape over the metal ends?
yeah
alright
Do you own pin crimping tools for these type of pins? @valid inlet
just checking before I write something up
I believe I do
That's a first
JST-XH is the specific type
in that case, do you know how to depin and repin these connectors?
If yes, then I will tell you just one thing - the wires must be in the correct order
I haven’t don’t that before. I tried once with a 1s battery that came loose but it just kept coming out
well, if either of those 2 pins is damaged, then you have 2 options
A) snip them off (with a bit of wire to give leeway) and splice on a new pin+wire salvaged from an extension
B) remove the pin and crimp on a new one
to figure out the order of those 2 pins, you need to measure their voltage against the next pin in line
there should be 1 cell of voltage between each two adjacent pins (1-2, 2-3, 3-4, etc)
(so like 3.2 to 4.2V)
Alright none of the pins are damaged so i’ll. go with B. If i’m not confident with doing this, would the best option just to buy another since they’re only about 30$?
if they're not damaged, then it's neither A or B
in that case you just slap them into a new plastic housing
can you get good macro shots of those pins?
they have a retention tab on one side (the flatter/rounder "top" side)
I just wanna take a look at the retention tabs, because those are necessary to hold the pins in the housing
buy a new one anyway while ordering the spare stuff to repair this one
more batteries = more better
Where are those?
alright, gimmie a minute, i gotta intake the pins
intake the pins
@valid inlet ?
I'm only asking about the 2 that came out
the rest stayed in so those are fine
ah
sorry about the wait, it was tricky getting the pins in focus
I can see the pin retention tab in the 1st picture. 2nd picture is from the wrong angle for me to be able to tell anything
okay I am officially too tired to think straight
2nd picture is where the retention tab should be i think it’s pushed in or smth
it's probably still there, just needs to be pushed back out
that is a repairable issue
with some sewing needles
as long as you're not shorting it to another battery pin, no
cool
since i’m not too confident with my skills and i don’t mind spending some money on some more batteries, how could i go about disposing the battery? i would think to use the destroy feature on the battery charger but i can’t really do that since the connector is broken
honestly
why
all you need is to bend one tiny piece of metal up
and then just move 7 wires over to a new housing
one by one
I don't like the idea of destroying a perfectly good battery xD
alright
I can give it a shot
for the new connector should i just get the plastic header or the header with wires already attached
that's up to you
I usually just buy extensions
they're useful as extensions until i need to sacrifice them
if I need housings, I have them
if I need pins, I have them
if I need wires, I have them
if you manage to fix that one pin, then realistically you only need the plastic housing
alrighty, and should i push the pins down? since in the picture it looks like the pins aren’t fully on the wire, don’t know if that’s how it’s supposed to be or not
wdym "aren't fully on the wire"?
in the first picture here only the end of the pin is touching the wire
i’m not really familiar with electrical stuff so sorry if this is an obvious question
nah I just find it hard to answer your question without seeing the pins in person 😄
can you send a picture of the pins from the opposite side?
the side opposite to the retention tab
if you want to, you can take out one of the "healthy" pins out from the connector and compare them side by side (carefully :D)
!repin
You might often come across an unusual abundance of wires on your VTX connector, or the ESC - FC connector not being in the correct order.
This video is made to help with that! Once you know how, it's rather easy and quick.

Thank you! I was literally just about to ask if there was any videos you suggest on doing this
this side looks normal to me

this will probably be even better

HOW TO REPAIR A LiPO BALANCE PLUG | As a BEGINNER!!
Today we figure out how to repair the balance plug for a Lipo! Not too hard but something you need to be careful with!
If you have a damaged balance connector, you should first check the voltages of all the cells and make sure they are within safe range. A broken balance connector could get ...
didn’t think this was such a popular subject
hah
is there a way to prevent this other than crashing?
everyone does this at least a couple times in their flying carreer
well, just securing the plug better
if it can't get into the props, it can't get chopped
well, tree branches can also wreck them
some people use rubber bands to hold them to the batteries, others use 3D printed (TPU) holders
everyone eventually figures out what works for them
it depends quite heavily on the batteries and the drone
i don’t think it went into the props, it could’ve though, i always check to make sure it’s not near them at the beginning of a flight so i guess it could’ve been bumped into them
this kind of damage is most commonly caused by a prop strike
that’s convenient, i just so happen to have a 3d printer and a full spool of tpu filament
i’m not sure
well, was worth asking just for the fun
all i know is that it’s red

V1:
Primarily designed for micro quads (16AWG) but large wires will fit in most cases.
Goal is to prevent the balance lead flopping around whilst flying.
Made a closed version since I tend to take Lipo's on planes and the highly appreciate if you not only the XT30/60 but also the balance lead.
V2:
Now 2S, 3S, 4S, 5S and 6S version
Increased open...
