Default Battery questions

I only have a couple of DYNAMITE Dyna-Sport 1500s, and would like get some newer/better/stronger/longer lasting ones.

I see quite a few 3000-3300s on eBay, seemingly very cheap. Could there be something wrong with them, assuming they are not used? For example, are there some companies "to watch out for", good or bad?

How about building my own batteries?
-What, if any, are the limitations (high and/or low) on volts, mah,
whathaveyou? For instance, Radio Shack has Sub C batteries with REALLY
high mah.
-What about wiring, series versus parallel? Series = speed, and
parallel = torque and runtime, correct? Would we be able to see/"feel"
a difference?
-What about 7 cell? What about more than 7?

OK....

firts, don't buy the radio shack batteries! Get a name brand battery.

As for soldering them together, I use a 45 watt iron from HOME DEPOT and 60/40 rosin core solder. You can get all this stuff at your LHS.

I peronally would avoid buying batteries from e-bay...especially if they are used. It is suprisingly easy to ruin a battery and not know it, so a used battery from someone you don't know is a bad idea.

If you're building your batteries, buy a DEANS jig and all your building problems will be solved. Always build your batteries in "series" not parallel. Parallel will give you more runtime than god, but you be a slug and no fun!

Also check out www.axiommotors.com for batteries if you're looking.

Default Clarification

"assuming they are not used?"

Just wondering about brand names? I believe Tenergy was one of the names that I saw. Im a newbie, so I wouldnt know what would be considered a "name brand". And Im not sure the batteries I saw at RS were actually RS brand.

I would like some volt, mah, runtime, torque, etc, "guidlines". Or point me in the direction of some previous threads I could read that contain the info I seek.

Thanks

Batteries to look for would be Hefty Cells,SMC,Promatch,Poleposition,EA, all these are reputable matchers.

I think www.maxamps.com and www.boomboombatteries.com would have to be the cheapest for assembled sxs GP3300's.

Default My charger

I have a DYNAMITE Vision Peak charger.

I would still like to know some of the other info, like what volts and mah would/could/should/shouldnt be used. Like I said, Ive seen some REALLY high mah sub Cs, but maybe volts would be wrong/bad, i wouldnt know.

And I would also still like more info on building my own packs.

Please bare with me and my newbie questions. Im not a dumb*%# (I can fix most ANY paintball marker), I just like to get a basic "elementary" understanding of things before I start tinkering.

For your batteries, I would definitely pickup a good discharge tray, the integy octane 2 is what I use and it does the job well. You really need to equalize the cells before charging them for best performance and maintanence.

As for what to charge them at, I do my cells between 5 and 6 amps depending on what class I am running and the cells themselves, also set my thresholds at 5mV per cell. You want the cells to peak in the lower 9V range. Mine usually peak out around 9.3V and really work well.

Maintained properly, they will last a long time.

I use Promatch and SMC right now, promatch being my favorite.
