Is it better to leave the opaque sheetwrap off for cooling purposes now that summer, at least in Texas is here or approaching? I noticed yesterday, the first day I have flown in 85 degree + weather that my batteries stayed hot a long time after a flight. I used a KR1700 Zagi pack, a homemade CP1300 Zagi pack, Radio Shack 1000 homemade pack.

I decided to make a cooling tube with a computer fan and card board warped in excess colored Zagi tape.

Thanks

The link doesn't work for me either. I can get to the main page but when I click on the How To button I get a 502 connection error.

Link works for me. The site should say "make sure when building packs like the one on the site that when doing end to end, the + side is soldered to the - side of the next cell". Dummies like me
would screw it up!!!!

Thanks for the tip Dave. Some things are just assumed, but I will make the change.

Wattage of soldering iron?


I've noticed that it takes a long time for the solder to melt with my 25 watt soldering iron. I'm afraid that if I tried to build a battery pack with this iron, the long time I need the iron next to the battery would harm the battery. What wattage iron whould I get?

I started off with a $10, 45W soldering iron from Sears. It worked just fine. I also found that it works better to use the very thin solder. I have since upgraded to a Weller soldering iron, and I absolutely love it, but that $10 Sears iron will definately do the trick.

Here it is: http://www.sears.com/sr/product/summ...id=00954042000

Thanks, very nice work !


Finally, I now understand how to do it properly, and will start doing it, rather than buying them ready.

Does that Sears 45 w iron allow one of those hammerhead tips to be used? I have a Weller SP40 and the plastic base where the metal rod comes in to it distorts from the heat causing the tip to be off center. Luckily I can get it fairly square by pressing the tip on a hard surface to bend it back. The Weller irons seem to cost a lot more than other brands and I don't think they are worth the extra money. I bought it just to use the hammerhead tip.

Thanks

The tutorial looks good. Photos are the only way to really convey what needs to be done.

I've been thinking of trying this, but I have so many other things going on, I haven't tried yet.

A suggestion -- get someone who's nit-picky and a grammar/spelling guru to proof your copy. There are numerous errors.

I have not actually used a hammerhead tip. I just used the widest tip that the Sears iron came with and it worked fine, but I think the hammerhead would be better.

Joe, Thanks for the tip. I'll get right on that. You definately need to try building your own. It is super easy.

I'm finding that my 40 watt Weller takes forever to heat battery enough to apply solder. The iron is tinned. I also use solder paste flux too. Its the flat side of battery that takes along time.
I'm thinking of going to a 100 watt to do batteries. Save the 40 watt for doing sermos and motor connections.
