Difficulty of Making Battery Packs

Hi

I am looking at purchasing an Xray T1R, but, because you have to make your own battery packs for the chassis design, I am a little intimidated about making battery packs (soldering, heat shrink, etc). How difficult is it to make them, specifically for someone new to this and should I let it get in my way of owning the car?

Than you very much.

With a battery jig, such as the one from Deans and a good soldering iron its really pretty darn easy. The key is a good soldering iron. I struggled making my own packs for a while but invested in a good iron and from then on it was smooth sailing.

Good luck!

if ur soldering iron is not hot enough, it's difficult to get a proper solder joint. i would suggest at least 80 watts for the iron...

Ask your hobby shop.

If you buy the car & the batteries from them, maybe you can talk them into doing the soldering for you too - if you're lucky free, or maybe for only a few dollars.

The first few pack I made were pretty rough, but now it's a piece of cake. I would suggest not practicing on expensive cells, maybe even get some cheap everreadys to practice on. And like everyone says a good hot soldering iron with a biggish tip will make life a lot easier.

a Deans jig and a decent soldering iron really makes it easy.

One thing to be aware of - if your cells already have shrink wrap, don't put another piece of shrinkwrap on them. In cars like the XXX-S, it can mean the difference between your cells sitting in the battery "grooves" correctly, or not fitting at all.

Battery packs are really easy to make, I use only a 50 watt iron and have no problems at all. I do have a digital tip temp readout on the iron, so I know when the iron is hot enough to solder another bar (usually takes 10 seconds between bars to regain it's heat) Just practice and you'll get good quick with it.

After a few packs you'll get the hang of it. Don't let the battery building get in the way of getting a car that runs saddles.

Rocky,
If it scares you to build a pack or you don't want to invest in a soldering gun,jig,connectors and wire. Just order your packs from www.promatchracing.com. They offer assembly of their packs w/connectors.

Yeah, battery packs aren't that hard. You just have to take your time when you build them. If you take yourtime they will lmost always come out really nice.

When you ask a question on this boards odds are you will not be hurting for answers! You found the right place my friend. Good choice on taking the plunge with the battery packs, good soldering skills really make the hobby more enjoyable.
