Ok well what I realized today is if your truck is being kinda slow and you have soem cheap 1500 or 1900 packs the best upgrade to make your car/truck 2x faster is get some gp3300's the place to get them is jax packs for about 35-40$ I put in some 2400s today and my pede was ripping wheelies and its mostly stock. I deffinitly would recomend any high mah cells.

I havent tried out 7cell but if anyone has post what you think about them.

yeah, im a racer for Jax Packs, and i must say they are the best packs ive ran. Before i started racing with them i went and baught similar packs from other companies, but i felt more punch and power with Jax Packs.

Higher capacity batteries allow higher amp draws at both peak and continuous, which can lend to more torque and top end. 7 cells will be a VERY noticeable jump from 6 cells. :D

I heard a rumor that 7 cell drains the batt's faster, But its probli worth the power.

im gonna run matched 6 cell gp3300 packs in my evader...already got em ready

Pro 2 its no rumor its just a fact that they drain faster because they are putting out more voltage to so they drain down quicker.

more voltage=more current (with same resistance)=more drain from the batteries. V=IR. It's worth it, however. You loose maybe 10% run time, but you gain much more than 10% power

Um i dont know about Gp3300's, i havent personally tried them. but comparing nicd cells to nimh cells, i find that nicd has better punch...so then wouldnt a better solution be to go with high quality nicd's? ie: those sanyo 2000's? :p

The extra power a 7th cell delivers is VERY much worth that 10% less run time seeing as how power increases by anywhere from 25-36%.:D:D:D

How did you get those numbers? I noticed a performance boost with a superrooster and low turn motor but it wasnt 25%

GP3300's supposedly have the same amount of punch as the best NiCd's, so you might as well get GP3300's for the extra runtime. I say "supposedly" because I went straight from cheap 2400's to nice GP3300's, never experienced any good NiCd's.

There's a forumla (exactly what it was, I forgot, it's floating around in the BL motor forum somewhere.) With a brushed motor it could be less noticeable due to less efficiency, more heat, which would cause a loss in power.

yea, i have a couple nice sets of sanyo 2000 cells and also 1700 sanyo cells as well(both of these were cream of the crop back in the day =P).

anyways, the 2000 perform quite a bit better than the 1700...punch is very impressive. after these guys i bought a pack of sanyo 3000s(i think it was 3000 or 3300...dont recall, i tossed the pack) stick pack and it was bad in comparison to the nicd's.
punch wasnt the same...but i did get more runtime. but i hear lots of good things about the GP's. i'll try them out. BTW, what should i set it to peak at on my charger? i use the pirana and i can set it at a certain amperage for peaking. i know for certain that they peak over 3300...does anybody have a safe number to go by?

The 2400's had great run time and a lot of punch. The 3000's came out and the run time was better, but punch wasn't the same. Ni-cads were actually better. There is nothing like the new 3300's. More punch than anything you have run and run time that is more than you will ever need. I was running 2400's for stock racing and 3000's for mod, but now I just run 3300's all around.

I believe conventional wisdom says to use a peak threshold of about 5 mV per cell OR LESS for GP3300's (and perhaps NiMH in general). Charge rate of 5 amps is about as high as recommended for bashing. Faster charging just beats up the cells more, and is most useful for racing, where you want maximum performance. If you have the charger I'm thinking of, it'll only charge at 3 amps max when plugged into the wall. You'll need a DC power supply to get a full 5 amps. 3 amps is fine, it'll just take longer to charge. A properly discharged pack will likely charge up past 3300 mAh, so don't worry about that as long as the pack doesn't get super hot. My GP3300's can charge over 3900 mAh without being overcharged.

I've haven't noticed any difference in punch between Sanyo 2.4s and GP3.3s, but the GPs last so much longer than the 2400s...
