cheech and coaliton,

I recently bought some of these packs from a racer who offered them at a reasonable price. They are SMC IB-4200 6-cell matched packs. Now, I am aware that there have been stories of these particular cells blowing up, so I want to be cautious with them (how do you maintain them?). I was recommended by the seller to discharge them to 5.4 volts and to charge them at 6 amps with no more than a .03 peak detect (cutoff). Now, the problem is that I only have a MRC Superbrain 960 and its maximun charging capacity is rated at 3700mAh at 4.5A. I have searched for info on this and some owners state that the 960 can charge more mAh than its claimed capacity. My question is, how can I discharge to 5.4 volts if my charger doesn't have that feature? Are there any cheap NiMh dischargers out there?

Sorry if I got out of topic but these batteries are specifically for the evader.

i never charged my smc over 4 amps, and i dont even bother discharging them, i just run the battery till it dies.

Sounds like the right thing to do in my case. I wanted to follow the seller's instructions on how to care for these packs mainly because of safety precautions. I suppose his maintenance instructions are aimed at racers who want to keep their packs in otpimum condition. Who knows, maybe I am feeling buyer's remorse after reading stories of IB-4200 cells blowing up [&:]

I have been charging the rest of my packs (GP3300s and IB3600s) with the charger's default setting of 3 amps and no problems yet. I guess I'll do the same with the IB-4200s. Would charging these at 3A be easier on the cells? Thanks.

About how fast would a Sidewinder 5700 make an Evader go on 8 cells? Thanks.[8D]

cheech4

45+ mph

rcmaster103

I'd say it could go around 50mph since I can go 40+ with a 6 cell on my 5700.

cheech4

40mph with the 5700 on 6 cells?? nice... what gearing??

rymansl2

Yea I agree cause I can do 45+ on 7 cells with my 4600. Of course I geared the crap out of it But it still counts

I should get my dog-bones this weekend...

Here are some pictures of my EXT waiting on some ST drieshafts.

cheech4

cant wait till you have it done,, this way you would be the first and tell people whats needed if they want to switch...

How come the Mamba Max 5700 can make a car go about 60 MPH on 8 cells then?

cheech4

i dont know about 8 cells but a 3s LIPO it can, maybe your referring to the mamba 7700?

T-Maxx88

Well, I found [link=http://youtube.com/watch?v=xaKebiUuH6I]this[/link] video and they are using a Mamba Max 5700 with 8 cells and are going 60 MPH. Are they just saying that they are going that fast or what?[8D]

cheech4

no where in that vid did they show testing for mph, unless i missed it... plus it doesnt look faster or that much faster than my evader speed run, so there no way it did 60 mph... i think they were blowing up some smoke....

rymansl2

Yea theres no way that was 60mph. Looks about 40-45 to me.

Hardin Valley Magic

Not to be disrespectful but it did show a gps with 60 on it.....But it didn't show them stopping and taking the body off. So one never knows. Just my pennies worth..

T-Maxx88

So about how fast would a Sidewinder 5700 go on 8 good cells? Only 40-45 MPH? Does the Sidewinder 5700 and Mamba Max 5700 have the same top speed on the same number of cells? I was also wondering if the Sidewinder woud take off slower than the Mamba Max since it can handle 70 amps instead of 100? Thanks for the replies.

ah-see

I'm thinking of getting a LiPo battery for my evader + sidewinder and i'm not really sure how much amperage the esc will draw from the LiPo. That way i can cut the costs on the LiPo battery and get something like 10C or 15C rather than the more expensive 20C and beyond.

anyone running a low profile tire and rim set-up. the tires and rims that come on the evader st are ok , but they are out of balance and a bit heavy. i seen some LP rear tires at tower but cant find the matching rims. im looking for litest,best balanced 2.2" tire and wheel combo out there. i hate it when i pick my truck up off the ground, then hit the throttle and the rear tires wobble like crazy ! drives me nuts.[:@] lol !

Frozen72

Did you glue them or were they pre-glued. My Mashers are VERY unbalanced. You could try ot balance the rim using some clay and a prop balancer.

cheech4

on 7 cells about 40-43, 8 cells closer to 50, i would say 47.. and yes both systems will have the same speeds if you going with the SW limit.. the SW can only take 8 cells on the 5700 where the MM can power 3s lipo. so up to 8 cells they will be both the same. as far as the amp thing the MM will be faster cuz it can push more power hence the price difference.. but the SW is no joke at 70, did you see my vid?? thats on nimh smc 6 cells. thats pushing out 35-40 amps, 70 amps is doubled the accelleration of what u see in that vid..

cheech4

road rage proline tires with 2.2 rims.. enough said..

cheech4

i saw that but i still don't believe it.. CC them selves said that 60 mph is doable in a 5700 with a 3s lipo and they were using a touring and buggy for there tests.. and i have seen on losi XXXT and T4 break the 60 mark with a 3s lipo.. but a heavy car like a rusty and on 8 cells nimh 9.6 volts compared to 11.1.. still hard to believe.
