hi,
is this looking ok so far? or am I destined for a fiery death?
any input gratefully received!
next step is solder 12awg silicone wire to the nickel then spot weld that to the battery + & - and join the 2 x 5s4p packs (once I’ve practiced soldering the wire to nickel and I’m happy it’s secure enough)
thanks!
I may put a thin sheet of acrylic or that stuff they use for yard signs between the 2 packs to keep them apart, just not sure how hot it can get and if it’d melt anything sandwiched inbetween.
or I may just wrap the 2 packs separately, hmmn?
put the wire on the dab of solder and add heat from the top; keep heating it from the top until the wire goes all the way through the dab of solder; all the solder should be fluid at that point
That way you should get a solid joint. The wire will get really hot, probably too hot to hold in your hand. Best to hold it with pliers.
Since you’re going to do the soldering away from the battery pack, you can take your time, which is good.
not sure what’s going on here, i have made 2 good joints that won’t pull apart but most of my attempts are like this.
I’m soldering on top of an aluminum plate, could that be taking all the heat away, or maybe my soldering iron doesn’t have enough ooomf?
I like ABS for this, nice and cheap and easy to get ahold of. Could of course print something. If it’s getting hot enough to bother abs/acrylic/pla, no bueno…
using some flux, and the solder is 60/40 (not sure if it’s lead free), i will try scratching up the surface a bit and grab a brick or some wood to solder on, appreciate the advice!
just tried it on a piece of wood and the solder melted well and made a solid joint,
the aluminum must have been sucking all the heat out of it, thanks!
Also Ive shorted a TB pack around 4 times by mashing the positive and negatives sides of the pack together. Besides scarring myself forever, it was fine. So you should be as well
it’s leftover red Sharpie where i was marking the cuts, should there be fishpaper rings on the negative ends?
i will be covering the sides in kapton tape
