battery help

[hasty falcon]

Battery wires caught in prop and when i go to move it it sparks, im very new to drones and have no clue what to do

[merry hound]

Holy shit lol

That was a while ago I’m assuming you got rid of it by now?

Or is it just sitting in a field?

That’s some nice St. Augustine grass

Are you in Florida?

Shits fucked mate

She’s done for

[merry hound]

I mean you could technically fix it

But the fact that the wires are being shorted in the photo, the cells might be drained already

[distant arch]

The fact it’s shorting means it’s done for

[hasty falcon]

Yep

She is back at home

Sepreated and cut lines carefully 1x1

[distant arch]

I wouldn’t trust it

[hasty falcon]

It arced a couple times its the only 4s i have so as long as its not one of my 6s thats all that matters, the 6s’s are all the same group number so that woulda sucked more

Grab a multimeter and check the voltage of each cells (have the -side on the black wires and go through each red wire) it might still be perfectly good, but you need the voltage of each cell

I don't think you can measure IR with a multimeter, can you?

I'm trying to google it but I'm just getting a bunch of tutorials on measuring cell voltage with a multimeter

[distant arch]

You could probably measure normal resistance

[burnt peak]

Oh, yeah no it was just a typo, I meant the voltage

I am not so sure how you could get an accurate resistance reading on a battery with a multimeter

[spare warren]

Brief sparks are fine. If the cells are a healthy voltage you can just crimp new XH terminals on. Be careful and don't expose more than one wire at once, putting each terminal into the housing before moving on to the next one

This is a common racing injury

[spare warren]

No, you have to calculate it while it's charging
