hi there,

after another disaster trying to solder some dean connectors, i thought about bullet connectors. I have seen them on some extreme big lipo packs but was wondering if there is any down side to use them on every pack?! i mean, why not?

thanks,

No reason, I use 5.5mm ones by Castle. Every so often you need to spread the males plugs a little to get the "bite" back, but Deans get a little loose too with use and time.

They are easier to solder. Just tin wire and bullet and while heating bullet back up, insert wire and watch for when solder on wire melts. Pull heat and hold for a few secs. Instant connection. I've got 2 pr to solder this afternoon for some new lipos with 12ga wire. Those are big and very hard to solder with deans.

I've read theres an amp level where deans start to get soft, they finally get hot, then bullets are preferred. But it on up there amp wise so I doubt thats a good reason.

hey duster,

thanks for the info. what do you do about making sure the battery connectors don't touch each other, you know what i mean?! do you use different sizes to make sure you don't plug them in wrong?

thanks

I do them one at a time when soldering so there is never a chance to short. As soon as one bullet is soldered, I fully heat shrink it to cover the outside. The only way left to connect is from inside the bullet. Then I do the other wire.

You can get these soft caps like used to cover nitro carbs to cap the open bullet while batt is not used. I use same size bullets and pay attention. Obviously plugging them in wrong can happen, I haven't done it. I have a healthy respect for the DC we play with. Screw it up and you're going to fry something!!!

Bullets usually have a hole drilled at 90 degrees to the bullet. I turn this hole so I can see in it when I tin the bullet and so I can see the tinned wire's solder melt when assembling. Then I know its time to remove the heat and let it all fuse together.

excellent info. thats a lot. what do you think about these:

Haven't personally used them but have seen good feedback on them (or something similar) on another forum.

They eliminate poss wrong connection completely though, which could be huge.

it looks like they are reg bullet connectors in a housing...i am checking some out right now at hobby city...

thanks again,
G
