I'm not even sure if we have to do it. I just did it because after discahrging what was left on the packs they charged more than they used to. I thought that if that happened discharging 300-400mA, what could happen if I did it to a complete pack.

That's why I did it. However I know of people that never did a complete discharge and their packs improved anyway, probably not as fast, but they did.

Hi Erik

Just obtain a BM - I am experimenting with some old cells - What would be very helpful is a guide at what would be the very best set of figures you would expect from a set of new GP3300's and the worst figures from an old set of cells - just as guide to know where we are whilst learning.

EA Motorsports- I got mine from ShopModel in HK- it took about 4-5 days to come in. I would try creating a different user.

Bat Man is awesome! I especially the noise that comes from the batteries so you know its gotta work!. Cant wait to see what my old batteries from 03 will charge at!

Thanks
Spintec!

Finally ordered mine and can't wait to try it...

One thing tho'.. anyone else experiencing packs go flat if discharged from a full charge? Erik, some explanation on this please..

Also, why is everyone posting 'results' of their dischargin from already race heat discharged packs? Seems like the packs are not on the same line when the Spintec device gets in to the biz..

Hello, sorry for my late reply... was out of office for a few days

Roedor:
- We also noticed improvements on nearly new packs, yes. They accept more charge.
- The biggest improvements are made in the first 3 or 4 cycles.
- We are working on a 4 cell version, but it's difficult to estimate when it will be available. Probably at the end of this year soonest.

Highwayman:
Looks like the I.C.C. project will be delayed a bit. Hopefully the first batch will be available around July, but don't hang me on this one See also the I.C.C. thread here
Regarding cycling your packs, I do not see any real reason to do a full charge and discharge just for cycling it. Just charge it all the way, run it for 5 minutes, then put it on the Battery Manager. Every cycle you do counts and reduces life time!
We have not found any significant better results between discharging a completely charged pack, or discharging the remains after a race.
And yes, due to the Coolflex current (blocks of 35 amps followed by a cooling down period) discharging takes longer than with conventional dischargers.


Micros_rock:
Yes, most people still tray their packs for equalizing.

Rod M:
We have heard of good results also on the Intellect cells. Anyone can confirm this here?

rcnewb2004:
If you run your packs completely empty, then the Battery Manager can't do much. You can not discharge empty packs My advise would be to not run your car until dead stop, you risk damaging your cells (reversal).

Simon:
You discharge your pack as soon as possible after racing. 500 mAh would roughly take 15 minutes or so.

jarkkom:
I have not heard of that before, except from Dotman on this page. Also I see no difference in doing a full discharge or only discharging the remains after racing. The process is the same, so why would the results be different? Maybe others can post their findings here?
People are posting mostly results of already raced ('empty') packs, because there is no real reason to discharge a fully charged pack (except for testing and benchmarking).

SagaMike:
The best packs I've heard of are close to 500 seconds, the worst are... well below that. Normal packs around 450 I believe.

Berger:
Good to hear! Hope this one is okay...

Hope I answered all the questions.... if not.... ask them again!

Yes, the Battery Managers have just been sent to Horizon. They will be there very soon now!

Hi Erik

Is this correct:
Immediately after discharging (about 3hrs for a 420 runtime) of a fully charged pack, I have to wait about 35-40 mins before any figures appear, with a message running - saying 'Maintenance - Please wait' or words to that effect. Is this correct?

I am not Erik, but I think that is correct. Mine does it too. If you listen to the batteries you can still hear it doing something during the maintenance process.

E.J-
Thanks for the info on the I.C.C.,you guys over there at Spintec take all the time you need to get this thing right. Last thing we need is a rush delivery to the market and have problems like the Spektrum's -JB

THanks for the reply Erik,

How much "juice" should be left in the pack then, for batman to have maximum effect on the battery pack?

SagaMike:
Yes, that's correct. In the 'Maintenance' mode at the end of the cycle, the Battery Manager chooses an other discharge algorithm. It then steps down in frequency and uses a different current-shape. We feel that this section of the cycle is the most important and is responsible for the performance increase (decrystallization).

rcnewb2004:
John_S is right, 500 mAh is a nice value. As said above, as long as the system goes in maintenance mode the results will be OK. We have not noticed any better results by doing longer discharges (like fully charged packs).
