    The option I've used for strip fuses is to glue the head of bolt into the base of the chassis (or otherwise secure it in place) and then you can fix down the fuse and the power lines (with ring terminals) using nuts. I don't actually have a photo but here's a video of me plugging it in.



    All the main power connections are made using ring terminals and M5 bolts.

    Good luck with the soldering (and be careful of the carpet)!

    Well stage 1 of my build went badly

    Ruined the EC5 connector and ordered the wrong battery connector, clearly need to neaten up my soldering again before attempt the connectors!

    I've seen and done worse. So long as the solder isn't touching each other and is solid on the connector, I'd isolate the wires, wrap it up with electrical tape and call it there. :P

    When you say wrong connector, which do you mean?

    Yeah dont mind the looks but it wasnt very strong and snapped easily and then made a mess of the connector trying to do it better so ordered more lol

    Turns out the one i got was XT-90 to XT-60 converter but ended up with another female end so gone for this instead https://www.amazon.co.uk/gp/product/...?ie=UTF8&psc=1 so can cut the banana plugs off and its good to go

    I've had trouble melting the housings of the xt pin connectors when soldering, so the contacts go all wonky and don't fit the other connector any more... I guess that's what you've had too?

    It can help to mate the connector you're working on with a spare connector, that keeps the contacts lined up and works as a bit of a heat sink...

    ... Though there's also the risk you ruin two connectors not one.... :'(

    Well it looks like the ones I ordered were pre soldered which meant were useless

    Im looking to replace my soldering iron as its a bit old, any ideas?

    Spent ages looking on amazon but even the ones with mostly good reviews have a few "DANGEROUS this will burn you" reviews so no idea lol

    Plus don't know how much to spend on one when will only use it for this lol

    So long as the iron works, it should be fine. What is the wattage?

    TBH, I don't solder connectors these days without a third hand, makes things that much easier to do. The presoldered one you bought will still be useful. If you cut off the banana plugs, like you mentioned, they become pigtails and easy enough to solder into a wiring loom. That is what I did before getting to grips with a third hand.

    I mean, if the iron isn't hot enough to burn you it's not going to melt any solder...

    If your old iron has a really knackered tip or is low power then you probably will have problems whatever you do technique wise. From what I remember something in the 80-100 W range is about right.

    I have to make do with a 25W! It works but I would prefer something like a 60-80W.
