>>1787069This is what I soldered up, all these bits from a local electronics hobby store. You need the clips that slide over the battery leads at the very least, I solder those kinds of connections otherwise they're weak as fuck, and I also like that trailer style of electrical connection. I have a battery charger that happens to have that same connector to its interchangeable leads so it just plugs right into the battery. It's worth the 20 bucks to get a cheap iron and the bits and do it proper, you will never regret having a 9$ soldering iron even if you just use it to do hash later.
