Wondering how to change a LiPo Connector? If so, here's my quick and safe method with tips to get the best results.
This example is shows changing the connector on a LiPo battery, which is usually the most difficult due to the high short protentional if you don't know what you're doing; but the same process would be followed if you have to change the LiPo connector on an ESC / similar.

    You make it look so easy, I always watch your videos even though I'm no into RC hobby, there's always new tips I can pick up along the way.

    Hi dude, I was due to replace some gnb27 connectors with some a30 ones. They are infinitely smaller, but the same principle is used. Thanks for sharing! 😊

    Great video. Soldering is comforting for me. I switched from EC5 TO XT90. I pretty much do what you do, but i love the vise technique which i will adopt. 😊

    Very good video John, I have never seen it done like this.
  • @stevendegiorgio3143
    I just cut the connector shell and the bullet pins come right out.Than incert them into the connector you want I did this and it worked fine.
  • @FPVenius
    Very nicely done and explained; thanks!

    Put a temporary strip of kapton tape across the back of the cup before soldering then if you have any spillage it just runs off and won't stick. Also have you seen the QS8 connectors yet? They're basically an enlarged XT90.

    This is one task that can totally ruin your day if you don't take your time and prevent a short at all costs. It happened to me once. The spark is bad enough, but the really dangerous part is if it welds itself to the other lead. If you can't rapidly separate them, it's like holding a hand grenade after you lost the pin and spoon. I was fortunate and was able to separate them but in that short time the battery became very hot, and one cell was smoked. I do like the new solderless connectors that have come out and have been converting my packs over. Either way, be extra careful.

    Very interesting as always ! Where are you installing/using those new batteries?
  • @garyowen3743

    Any R2 updates ? how are the parts holding up and are the seams starting to show cracks in the paint ? any events with the droid ?
  • @flyboywbl
    Though you can plug ec5 into xt90 if you are lazy
  • @thomaswalton9089
