Default Do I really need matched batteries?

Same as question. Normally, I'd expect people to say so, since they offer higher voltages and longer run times. However, I plan on running sportsman stock at the local track, so I'm not totally sure I would need them, as the competition may be quite low with inexperienced racers. About 15-20 racers show up for that class every weekend. Sometimes people with crappy 1500 packs win, sometimes people with $80 matched packs win. So, my question is, do I really need matched batteries? The cost of matched cells is really getting to me. If the answer is no, I'll probably pick up some of those unmatched 2400 stick packs from Orion for the Emaxx and convert them to saddle. (Two six-cell batts for only $45!) Sorry for the long post.

You can get a good deal on matched packs at www.promatchracing.com and if you want them in saddle they will do it for you for some extra cash. Matched packs are not necessities but they certainly help. If you do get matched packs just make sure you look after them.

Recently, I've bought a Sanyo 2400 match saddle pack. I've also bought some Sanyo 1700's, wich I soldered together in a saddle pack myself. Honestly, I'm dissapointed about the 2400's. The 1700's got more punch and they costed half the price. They are charged and treated the same way.

What settings are you charging the 2400s with? There is no way they should be outperforming 1700s...

As for matched vs. unmatched, I would always rather pay a little extra for a "low-end" matched pack than unmatched batteries. Everything will be more consistent, and the pack (in theory) should last longer when properly cared for. Also, there are plenty of "budget" matched batteries available... for example, I have had great luck with the < $40 2400 packs from Integy.

Joe, Just go with the less expensive packs, I use unmatched batteries and they work just fine for sportsman stock racing.
It really just depends on your budget, My budget is very little.

Even for sportsman, i would get a "good" matched pack... not the best... but a good one that will last you a while. As you get better, you will be able to keep using the cells, and not just make them into practice packs as the guys who bought the cheapies will be doing. If you take care of them, they should last you a long time.

Cool

I run in the sportsman class here, and it is very competitive. The "good" guys in the pro stock class are doing 30, 31 laps, while us in the sportsman are doing 29, 30. So really, the pro stock is more like the A-main and the Sportsman is the B&C mains. I have only ever used matched packs, and I always plan to. I have some 75 dollar SMC 2400's, and they are excellant. Just make sure you take good care of them

I use 1700s for F1 racing indoors, and I have never had one of my 1700 packs "out punch" my 2400s... but that may be because my 2400 packs are all pretty nice matched ones. The 1700s I have are all the yellow/black Panasonic ones, don't know if that makes a difference either.

Just buzz your 2400s at 5 or 6 amps, discharge at 30, and they will have plenty of punch! Just very little runtime... but who needs runtime in 5 minute stock anyway?

Joe,

IMO, you should always use matched batteries. You don't necessarily need to get "Ultra Intense Voltage-Major Runtime" packs if you just plan on racing locally. Matched packs will help ensure that your pack won't go flat halfway through a run because one cell discharged before the others. It's kind of like having to run on 7-cylinders for the rest of the race. Most matchers will have "average" matched packs available for 1/2 to 2/3rds the price of their "top of the line" packs, so it pays to have cells that you know are going to discharge evenly throughout its discharge cycle.

If you do decide to get serious about competing though, with practice you will eventually reach a level where the difference between winning and losing will be in the batteries you run.

Joe: No you don't need matched packs. I honestly don't notice the difference between matched and unmatched packs. I am not a really hardcore racer or anything like that, so it really doesn't matter to me. I am not saying matched packs aren't best, they are, but if your tight on your budget, don't worry about the matched packs.

I will simply say this. I manage to beat a lot of people who use high end, matched, voltage increased cells. I have two matched packs that really aren't any better than my unmatched ones, atleast as far as I'm concerned.

There are many factors that contribute to going fast. The cells are only one of them. So don't be overly concerned with them.

If you dod decide that you need matched packs, try www.speedtechrc.com. they have Integy Matched packs that cost less than some companies unmatched packs! Some people will tell you something about the numbers not being as high as Integy says and all that crap, buy don't worry about it, their high enough for what they cost, and they are matched. So thats another option if you feel the need for matched goodies.

Good luck.

If you have any of the good stock motors out there, the batteries are the bigget effect on the speed and acceleration of your car. Invest in maybe one really nice pack for the main, and some decent matched ones for the heat. Plus, they last longer, so when you replace your batteries you can use them as practice packs!

Buy some used matched packs for cheap and decide what you think. One time I bought 4 1700 matched packs from a guy who took great care of them for 48 bucks (That is 12.00 a pack) Worked another deal where the two matched 2000 packs I got for 15.00 dollars a pack. At those prices you can't afford to run unmatched packs!
