Default Battery Building Question

Hey guys

i put a small dab of shoe goo inbetween the batteries and then get a piece of strapping tape to hold the battery together. i let it dry overnight, and when the shoe goo dries, the pack is solid.

mmmm not sure what glues you have in the US. I know here in Aus we have a glue called flash. when you have situtions like this you buy a bottle of flashback and apply it over the area and bingo-problem fixed. Zap a gap might have a zapback type of thing ?????

I could be wrong but I think the CA does someething to the plasti Shrink Wrap on the cells and this is what causes the discoloration... I know the Pack I just built did the same thing and 6 years ago when I built packs they did it too (looked terrible on black cells) but yah I think thats whats happening the ShoeGoo Idea sounds like something to try.

the ca glue actually melted the shrink wrap a bit and distressed the wraping causing it to discolor there is nothing you can do except disassemble remove old wrap,put new on, and then glue with shoegoo only

i would discourage you from usin ca glue because it breaks down the shrinkwrap and on some of my cells it has cracked around the glue and when the cells get hot it shrinks and gaps apear in the wrap

We normally use FenderMender or Zap-A-dappa-Goo I think thatīll be almost the same as Zap a gap or other body-repear stuff.

In my expirience the problem with CA is not that it reacts with the shrinkwrap, but it tends to leave a white shade if the gleu dries in a damp/humid room. It reacts with moisture, on a hot summers day there will be no white shade. I have had the same problem while sealing the edges of my CF chassis. Almost looked like SSG!! The only way to get rid of it was pollishing the chassis!!!! took me about half an hour.

Donīt know if youīll manage to do that to your battery pack!!!

GOOD LUCK

I usually place the loose cells into the car that I'm going to be racing in. Put a small dab of shoo goo, and either tape or use the battery hold down (flipped upside down to prevent the shoo goo from sticking to the hold down). I've found this to work well, as the batteries will be conformed to the chassis, allowing them to "sit" into the battery slots.

Edit: rc411.com has an article on soldering in their "how to" section....

Default Use good solder!

If you use good solder like Kester 60/40, or deans, with a 40+ watt wide tip iron, a deans jig, and good battery bars, you shouldn't need any adhesive at all, it's just extra weight, and retains more heat, hell i can take one of my older packs that i dont use any more and throw it across the room or toss it 15 feet in the air, if you do it right they wont come apart.

everytime this has happened to me, i have never been able to get the white stuff off. a way to hide it is to spray a little oil (wd-40) on the cells and wipe it clean. it will last for a while but it will come back. i know it sounds korny but it should work. i don't glue my cells together. this has happened on other things i've used ca on.

I always use CA glue from Target, and I've never had any of the white shade on my batteries.
But if I use it on something made out of plastic it does.
Maybe it also have something to do with the shrinkwrap you use.

Just curious, How exactly do you polish glue on your chassis
