A couple Battery Questions

[Red01MustangGT]

So I'm trying to figure out what route to go with Batteries. After looking into NiMH I thought that was the way to go because I can get 3000+ mAh and they apparently perform better throughout the charge. But people are also recomending I go with 7 Cells to get more power out of my Stampede (don't quite have it yet hopefully by February). But I can't seem to find a 7 cell NiMH pack. Should I build my own? I have never built a pack before but it doesn't seem too complicated, I would just be afraid that I couldn't get the connections soldered well enough to handle a hard jump. Right now I just have 2 NiCd 1300 batteries that are really old, not sure at this point if they will hold a charge as my timed charger is broken (the timer won't work). So I thought while I was looking at getting a new charger I would get new batteries too.

So Any feedback on which way to go, NiMH or NiCd? Also 6 or 7 cell?

NiMH are what you will most likely want, because who doesn't want more runtime? A 6 cell pack will give you plenty of power, and a little more run time than a 7 cell. But if you REALLY want a 7 cell, you can order one here- http://www.unipros.com/cbpsite/packs.asp?cat=CAR&session_id=237881 However, they aren't very cheap as you can see. Also, the Stinger motor on the Pede runs pretty hot as it is, so adding a 7 cell will only make it worse.

a 6 cell old 1300 compaired to a 6 cell ni-mh 3000 or 3300 will be a night and day diff. i was using new 1500 cad's then i went to a gp 3300 nimh. that was like putting a electric motor on crack. :eek: . just try a 3000 or 3300 6 cell . you wont be disapointed!! in fact i have a 7 cell 1700 cad pack and it is not it all faster than my 6 cell 3300 nimh batt's !! :D

Hmm, thats interesting, that gives me more to think about. I did read somewhere that the stampede would go about 18mph out of the box with a 6 cell and 23mph with a 7 cell. I know it would run hotter with 7 cells and I would probalby have to gear down a little for everyday use, but I like the idea of having extra power when I need it.

And thanks for the link Steve. I may consider it. I do want to support my local hobby shop though (as it is owned by my uncle) ;)

Red01MustangGT - SPC (http://www.specpointbatteries.com) sells matched (with labels) and assembled, GP 3300 packs at great prices. For what it's worth I really don't think you need a 7-cell pack for a Stampede. I suggest you purchase 6-cell packs and then buy a faster motor if you want more speed. I've owned a Stampede for many years and I run 6-cell, matched packs in it. Some days I run a 17-turn motor in it and other times an 11 turn. The 17 turn gives good performance and great runtime. The 11-turn motor is insane! Great acceleration and top speed, but the runtime suffers somewhat.

Hey Guys; Don`t Forget about Ni-MH Batteries and the Whole DisCharging Mess that comes with Ni-MH Batteries.
I`ve read in R.C. Car Action that those batteries will give you a Work - Out.

NI-MH Batteries are good for long running times and will somewhat make you car go faster.

I don`t like to Over-Work Myself; and I feel NI-MH Batteries will kill me.....Ha Ha!

It`s Up To You.

Take Care.

As long as you have a charger that supports Ni-MH, I would definetly say to go that route.. and frankly if I may say so, GP cells are superior to Sayno cells in virtually every way. Stick with GP3300's, you can't go wrong.

Sounds as if you're a basher, if so, check out http://www.surgeworldwide.com/order_basher_batteries.html I would go for an assembled pack if you are inexperienced at building or do not have a very hot soldering iron as you can seriously damage your cells by transfering heat into them during the assembly process.

Cool Thanks, I ordered two from here: http://www.promatchracing.com/gp3300.htm Same price ($35), but the #s look a little better.
