Spintec Battery Manager

I got my Battery Manager a few weeks ago and ran my packs through a few cycles to see if the BatMan made a difference. My results were not very positive. I charged 14 packs completely which charged to an average of 4000mah. I ran two cycles for each pack. These were the discharge numbers: The average runtimes were around 370...avg volts 7.60, energy avg 82, capacity 3300. The interesting number was IR. the first cycle had IR's in the 30's and 40's. I expected the second cycle to be lower, but they actually went to the 40's and 50's. I cycled a brand new EA pack with only one run on it that registered a 59.5 IR. I wouldn't have been too concerned by the numbers except I took 8 of the packs to the track last weekend to test and each performed poorly. My cars lacked punch and topend. These packs had performed well previously. I'll do more testing, but I was curious to hear from other people about their experiences

you going to hesperia on sunday? i can show you the readings ive taken on my 6 race packs.. each time i discharged on the Spintec, the IR goes down (usually 10+).

For the US guys, there will be a large shipment to Horizon next week. So very soon you can easily order them through your local hobby shop!

Thanks antonio...
BTW, when do you expect the ICC to come out?

...So would you still want to tray batts after using the BatMan?

Yep,
I still do. Just to be sure all cells are balanced. It doesn't take more than a couple of minutes to equalize them.
Regarding new packs and 3700:
My 3700 are brand new and my new packs are 3700
I'm doing the routine after all the runs but I can't say that the results are much better because the packs are barely used
However if the BM does the same it did with older packs, I assume that the degradation I found with the 3300 will take a lot longer to occur.
I wasn't expecting too much from my 3300 anymore. To be honest it was quite a surprise.
With one if theses "revived" packs I was able to drive consistently in the front of a friend of mine using brand new VTEC3700.
Not that his car was bad or anything, but because my car/motor/pack combo was perfect. The car would just jump out of the curves and that has a lot to do with a good pack. I didn't feel the mushy feeling it used to have from minute 3 till the end.
In conclusion. If it did what it did with my old packs I'm going to use it on my new packs ALL the time. If I can make them live for a a couple of months more it's worth the investment in a big way.

But what I'm saying is that with some 5 years experience with the old version, I could still race my 2000 packs as they're kept in good shape. So I expect it won't be much different with the new improved version.

I just got mine today, it is much smaller than you would guess by looking at the pictures,

Hey guys,
I am just a newb here, and I don't own a batman, but all this talk has just gotten me excited and curious.
I run modified, and I dump my packs ( or get pretty close anyway), will the batman do good for me? I mean there isn't very much left for the 35A discharge to do anything... Will it produce the results that I have been viewing all through this thread? I run GP3300s matched 1.178+s.
I am not sure if this question has been asked, but I REALLY don't want to read through 264 replies of all sorts!
Thankyou!

This is from my personal experience and it seems to be consistent and not a one time effect.
I have 5 GP3300 packs that were not accepting more than 3300-3200 mAh and were having a lot of trouble delivering 5 minutes on the track.
I discharged what was left in them with the BM. After that the packs accepted more charge and the Peak Voltage was lower than it used to be.
Then I charged them completely and discharged them with the BM. It takes a couple of hours to discharge a fully charged pack.
Now, ALL 5 accept around 3800-3900 peak at around 9V (not 9.3 as they used to) and on the track they almost seem like barely used packs.
Run time is not an issue with 4 of them and the punch is awesome.
Now I'm using the BM ALL THE TIME after running with the GP3300 and the GP3700.
It seems to me that I've found the right tool for the job.

how many times do i need to cycle them, or regularly do i need to cycle them (complete charge and discharge)

Hi
I've got a question. When do you discharge your pack with the BM ?
is it before running your pack or after ? i mean when you arrive at the track you discharge the rest of runtime from the last cession and after you tray them and charge
or you discharge the day before or just after your run and keep the cell discharge and just tray them the next week of training ?
I've got around 500 mah after 5 min race (modified are 12 turns in france ) how long does it take with the BM to discharge 500 mah ?
thanks to give me your experience
Simon

Do you have to connect your packs to a discharge tray after discharging with the BM?
