Hebiki, looking forward to the review!

Ghostfit, don't worry it will not explode after 1001 cycles
No there is no implication, it will just keep on counting. Until 9999 and then starts at 1 again... let me know as soon as someone reaches that!

I used the Spintec on every battery I own. I am wondering how often I need to use the spintec to retain any of its benefits? I can tell you right now with it taking so long to disharge and do its maintenance cycle, it is not possible to do all the packs in a race day. Many of my packs are deadsjorted as well-so that further difficults the time thing. I cannot let these packs sit around for hours waiting for the spintec.

also-is there any data to support that the Spintec has its greatest affect on brand new packs. For example you use it right after the first cycle-or even before the first charge to take any residual charge out of packs.

Thanks in advance,
Ray

Will do ! ....Any prizes for being the first ? like a new I.C.C unit ?

hey ray.. i know what you mean. but even though it may take hours.. as long as you do them as close as you can ... you can see solid results. all my packs went from IR of 50..and now they constantly hover around mid 20s. average voltage went up about .1x for each pack. as for brand new packs. my newest packs stay between 25-35IR (since i dont use them as much as my practice packs)

will you recommand discharge the cells by Batman everytime after run?
will it hurt the cells?
by the way...before charge it...will you also discharge the cells by Batman?
as currently i'm using Novak Smart Tray dicharge each cell to 0.9V prior charging.....

What is the last firmware version of this Spintec Battery Manager ?

It is 1.5 the last available ?

Thanks

P.S: The manual state that also NiCd can be used ... does the decristallization happen also for NiCd ?

Picked up the BatMan last week and have now completed one BatMan cycle (from full charge) on each of my far-less-than-stellar batteries (3300s). The funny thing is, when picking the top three packs to race with, I don't know if I should focurs on capacity, run time, energy or IR (look at those IR numbers - OUCH). So, I'm asking you guys what you think. How would you rank these batteries (1 to 6) and why? You can also tell me if you think it's time for new batts. I run stock. Thanks.

Pack 1: Label voltage 1.179; Avg. Volt. 7.73, Energy 117, Capacity 4512, IR 60.0; Runtime 507

Pack 2: Label voltage 1.184; Avg. Volt. 7.71, Energy 116, Capacity 4449, IR 41.8; Runtime [can't tell what I wrote!]

Pack 3: Label voltage 1.170; Avg. Volt. 7.65, Energy 122, Capacity 4733, IR 50.5; Runtime 532

Pack 4: Label voltage 1.162; Avg. Volt. 7.61, Energy 124, Capacity 4834, IR 41.0; Runtime 543

Pack 5: Label voltage 1.173; Avg. Volt. 7.74, Energy 105, Capacity 4035, IR 45.0; Runtime 454

Pack 6: Label voltage 1.174; Avg. Volt. 7.60, Energy 119, Capacity 4656, IR 61.5; Runtime 523

Thanks for your help!

it will not hurt the cells if you use the Batman. i use it to discharge ALL my packs after every run. the Batman will bring your batteries down to 5.4v. so before you charge, put it on your Novak Smart Tray and equalize. then you are ready to charge. repeat the process

yes. you will receive the latest firmware. all batteries eventually will start to "crystallize" the Batman will help break up with the crystallization and help lower the IR in your batteries

ranking order:

1. Pack 4
2. Pack 2
3. Pack 5
4. Pack 3
5. Pack 1
6. Pack 6

i ranked them according to your IR. i run mostly stock with some 19T. a lower IR will give you more punch. you'll notice your IR go down even more once you run your packs (either in practice or in a race) then discharge it again on the Batman. purchasing new batteries will all depend on your budget and how long you've had these cells and how you treat them. but since you have the Batman now... taking care of your cells just got easier and the new ones you do get will last even longer now.

So you'll rank the IR over the Average Voltage? I thought in stock the voltage was more important. I race stock and some of my IR's are pretty high but I though it was ok because the voltage was still good. Opps..

Hi guys,
I do know that this BatMan have not been designed with stick pack in mind, but my results look very wired.
Just pick up two of my warst packs for make my first test.
One 2400NiCd no name (Conrad)
One 3000NiMh from Sanyo (old and abused)
Both packs use a Deans plug
In order to get a clean connection, I put a new unsolder deans male and from the two free metal part I have connected the BatMan.
The NiCd that perform really crap (50% top speed then my GP3300) was almost discharge, and after 20 second (BatMan time, so around 200 real seconds) did copletly discharge the pack, and reported an incredible 57mOhm internal resistance
Done this I plug in my Sanyo 3000 (fully charge 1 week ago) pack and the final result is even more incredible: 315sec 7.47v 70.6j 2800mAh 22mOhm
22mOhm for a cheap ready made stick pack is impossible!
I would have expected that having additional cable and the deans connector in the middle would have shown me very high internal resistance ....
Other strange thing is that the voltage reading is chnaging quite a lot, it show for example 7.6volt and after a fraction of second is show 7.4volt, quite a big gap!
Is my BatMan ok and the problem is just the extra Deam connector?
Should I sold a male Deans in my BatMan for have more accurate reading , since I use only stick pack with Deans ?

Thanks

Hi,
Maybe I got an idea way my Ri are so high.
It would be nice if Erick can comment on it.
Since I use stick packs with deans, I have two parallel cable long around 10cm (5cm from the pack and 5 cm from the BatMan.
These two cable could act as capacitor/condensator ... so when the BatMan make the inpuls for discharge some corrent is comming from the capacity accumulated in the two cable and not from the cells itself ... so the RI look much better ... if I put an additional capacitor in parallel to the pack, I'm sure I will see incredible low RI value!

One other thing I have notice, a single second of the BatMan is equivalent of 25 real seconds. From the reported data 315sec and 2800mAh it also raise that it is not a 35Amp discharger, but a 32Amp
Considering that the time is 25 slower, the battery is in fact discarged in avarage 1.2Amp ... not a impressing but still reasonable for use between two races ... assuming no more then 1200mAh left in the pack

Anybody is using BatMan with Dean stick packs?

PS the most cool thing is the sound that the cells are doing while discharged by BatMan !

Hi,

How many cycles did you do to bring the IR from 50 to mid 20s? I just started to use it and found IR of some of my packs are in 50s and I would like to give myself some hope...

Many thx

James

There is something wrong with this BatMan !!!

Grazianos reported a strange report (consisten with his other tests*BTW) :
Pack 4: Label voltage 1.162; Avg. Volt. 7.61, Energy 124, Capacity 4834, IR 41.0; Runtime 543
He see a capacity of 4834mAh !!!
Even assumin he tested a 3700GP, there is no way to get out of it more then 3500mAh with 35Amp discharge !
My second test over my crappy 2400NiCd from Conrad (even not good for training in any 17T class car) did report:
468s 7.43v 104j 4161mAh 61.5m
4161mAh for a old abused 2400NiCd is absolutly wrong!!!!!
On my second test I'm having still 6.5V and 515sec run time!

During the night I try to fully discharge my fully charge Sanyo 3000 (it took only 2500mAh since is an old and abused pack) ... and as good morning I see a stupid result 1 sec runtime ! .. I guess the pack has been fully discharge, and after it finish the first cycle for this packwithout any interaction it most probably decided to start a new cycle again !!!!

As well after finishing discharging , my BatMan stay around 30min in a maintenance mode , quite anoying long !

Is my problem due to the stick pack usage withe Deans ???
Did I got a bad BatMan ?
Or is just a fake crappy product this BatMan ?

How the hell this BatMan can state 61mOhm for a crappy old NiCd ready made stick pack ???????
Is this BatMan so stupid that it can't detect any additional cable or resistance in series with the cells ?????

Anybody out there is using BatMan with stick packs and Deans ???

Thanks

e_lm_70

PS: The BatMan that I got for sure was not an intentinaly bad BatMan, since I did start firmaware as first thing, and report ver 1.5 and 0 cycle executed!

Hey James... about 3rd or 4th discharge cycle... i saw my numbers drop below 40. now around my 5th or 6th..its hovering around the mid 20s.
