Default ib3600 verses ib3800 for off-road stock?

Is there really that much differance in punch/performance for off road stock racing? All numbers being equal accept runtime?

nope, however. gp 3300s would suit you better. They are lighter so better suited for stock.

Sorry party wagon, I think the vast majority of racers on this site would disagree with you. A GP3300 is indeed lighter than an ib 3800. But, the 3800's have more than enough rip and top end to compensate for the weight difference. If you happen to look at the stock or 19 turn a-main at any recent big carpet race, you will see that 3800's fill the grid, with the occasional 3700's. I'm sure that this would not be the case if gp3300's were still the battery of choice for stock racing. You can get a decent set of new matched 3800's for around 40-45 bucks, which can be used for a variety of applications.

I wouldn't be fooled into believing that a lighter car is always better in off-road racing. In many cases, adding weight in certain areas of the chassis can improve the handling of the truck or buggy.

Numbers is what matters in stock racing...highest voltage is king, you all know that.

IB3800 packs put up better numbers than 3300's and 3600's and many 3700's (though GP is very close with the 3700's).

here is deal. I have 2 kids and me all racing at the same time. You figure 3 heats and a main that's 2 packs per outing for each, 6 total. I can get 6 packs of 3600 for $200 or 6 packs of 3800 for $300.

I am sold on either 3600 or 3800. So comparing those two is really what I am after. Although I thank you for your input so far.

I would just ask yourself how serious you are. Is it more racing for fun then get 3600s or serious then 3800s. For stock offroad you wont notice a huge difference between a 3600 and 3800. I still run GP 3700s and they are great. But I have some 3800s on the way.

Yea wagon, I think you need to do some further testing.

I found 3600s will SOMETIMES out perform a 3800.Im not saying id rather run them, but it happens.If its the money thing then just get the 3600s.

Take a look at Team BrOOd batteries.They have the cheapest 38's Ive seen in awhile.Something along 1.190-1.196 for $35 +/- at a 35amp discharge.These are better then the packs I got at promatch and paid $65/pack.Just a suggestion, to what I wish I would have done.Not nocking any other companies, Team BrOOd just has the best prices Ive seen. So if you need 6 x $35 =$210 and maybe since your making a big ol order, they might throw in some battery bars or something.Good luck

Run time makes a difference in punch, especially at the beginning of the race.

The voltage numbers you guys see (and love to go apesh!t over for some reason) are average voltage numbers...therefore, the average voltage of the cell throughout its run-time. Take two cells with 1.165 average voltage, one with 20o seconds and one with 400 seconds (for explanation's sake). Because discharge curves are pretty much linear, both cells will have to spend an equal amount of time both above and below the 1.165 volts mark for that to be the average voltage of the cell. In the above scenario, the cell with only 200 seconds of run-time will discharge from its maximum voltage much faster, falling below the 1.165 mark faster, and reaching completely discharged faster, than the cell with 400 seconds.
