Hi, I'm a beginner so please forgive my ignorance! I just crashed my newly built F550 hexacopter and damaged the balance plug on the LiPo battery. Does anyone know where I can get a new one fitted? (I don't feel confident in attempting myself, despite building the drone OK). Thanks in advance for any help

Hi buy a balance plug and heat shrink from giant shark or H.K this is important make sure you buy some lead based solder and low wattage soldering iron .The correct way is to strip back the wires push the heat shrink cable up the cable out of the way .Tin the wires and mechanically join the wires(you hook the tinned ends together) before soldering them i prefer to twist the wires together and then tin and solder the wires in one go when it comes to small gauge wires.Pull down the heat shrink over the join and use the iron to shrink the heat  shrink.

Not forgetting that you need to thread the heatshrink on for the individual balance wires, and keep it away from the heat, BEFORE you make the solder joints up. :''

Even more important only do one wire at a time and fix the heatshrink on that wire before doing the next!!

If you bought the battery from a good LHS they will probably fix it for you.  I'm pretty sure my local one would ;).

Otherwise you're pretty much on your own. It's not difficult if you have the right tools and you're careful, as the others have said.

If you do try to repair it yourself do it in an open space in case you short circuit if so you don't set your house on fire,,, :xx

Cut and repair one wire at a time you will avoid shorting any wires take your time.A small pair of side cutters and pliers will defiantly help

One other caution...  If there is any chance that the LiPo itself (and not just the balance plug) has been damaged in the crash then I would discharge it and dispose of it.  I'd rather err on the side of caution than have to deal with a fire insurance claim for my house.

just a thought, if all you damaged was the plastic of the plug you can buy a new lead, then one by one push on the little tabs that keep the connectors in place in the plastic and put them into the plastic hosuing of the new plug.

if a wire came loose you can simply peel back the foam pad on the end of the pack and see the point it came off.
unless you're confident it's best not to muck around here because you can easily solder acorss the gaps and cause a short.
