MRC Superbrain 809 AC/DC Peak Charger good for newbie

Post by Goon » Mon, 16 Aug 1999 04:00:00



Hi all.

Ok, I have one last part to choose before I order.  The charger is the
piece that I find most confusing.  There are so many features that I
do not understand... probably because I know very little about
electronic properties.  Anyway...

Is the Super Brain a good charger for a beginner.  I am getting the
following for bashing around.
TAO3
Futaba Magnum JR w/ESC
Trinity AmpMax 1400 (couple of 'em)

1) What is a peak charger... is it the trickle thing that I see in the
description.
2) Do I have to worry about "overcharging" with this charger
3) Does the charger do a "charge over a really long time" charge that
I have read is good for the battery every once in a while?

If anyone has a web site that goes over battery basics, I would
appreciate it.

Thanks,
Goony

I'm not sure about the super brain, but a peak charger means that it stops
charging when the battery is full, so you can't overcharge it. If it is a
fast charger, then it should be able to slow, or trickle, charge your
batteries as well as an option. If it is just a trickle charger, then it
will take overnight as opposed to half an hour.

Although I have read comments on this newsgroup that were favorable to
the Super Brain, I wanted you to let you know what else I have heard.  I
have two friends that I race with weekly.  They both worked at a LHS in
my area.  When I was getting into this hobby, they strongly advised
against getting a Super Brain.  They said that nearly every one they had
sold at the hobby shop had come back with problems.  Then, this past
Friday night, another racer I know who did acquire a Super Brain second
hand, had it malfunction on him during the racing.

My advice is to stay away from the Super Brain.  I suspect that they can
be good chargers, but that their quality control is very poor.  If you
want a charger in that price range, try a Duratrax Piranha or a Hobbico
925 (the Hobbico has been discontinued, but you may still find one.)
Both of these chargers should be available for around $40.  They are
virtually both the same charger.  I have been using the Hobbico for 3
months, and it has worked flawlessly.  Be aware, however, that these are
simple peak chargers, and can only be used on 6 or 7 cell NiCd packs.
If you plan on getting into racing that requires 4 cell packs, or maybe
into gas racing where you need to charge receiver packs, or if you are
going to buy some of the NiMH 3000 packs, then you should consider
stepping up to a charger that is more versatile.  Good Luck!

If I had a chance to buy a Millennium for $65, I would jump on it.  They
are popular at my track.  I know one fellow who has 5 of them.  They
seem to be very flexible.  The delta peak can be adjusted, so they are
capable of charging NiMH packs.  Only drawback is that they are DC only,
so you need a power supply.

The Tekins, particularly the 112c, are also popular at my track.  The
drawback here, according to recent posts to this NG, is that Tekin is in
some sort of internal turmoil at the present time.  Apparently their
customer service is severely lacking at present.

I have one of the Super Brains and have had it since 9/98. I have
repeatedly charged stick after stick without letting it cool down
although I wouldn't recommend it.  I have had no problems with it.  I
don't put it under the stress of racing but have charged with it many
times and have forgotten and left sticks hooked to it for a week with
no noticable harm to it or the battery.  It does get extremely hot
after about 3 sticks in a row and emits a plastic smell which R/C Car
Action I believe reviewed and not the same smell.  It just seems to be
from the stress of multiple charges.

It's great for the money and I have not had any problems. I like mine
but you have to choose for yourself.  If you plan to race there may be
better ones out there plus I don't "think" it will charge the new
3000mah sticks but someone may know for sure. (How bout it fellows?
Anyone know for sure?)

Good Luck!
Bill

I too have a SuperBrain 809.  After I had it for a few weeks, it
overheated and actually melted the case (in fairness, it was about 94
degrees that day and I had it under the hood of my car which was very
hot).  When the case melted, I could not push the Select button any
longer.  I called MRC and they replaced it without question (it did
take a while and I did have to call and 'complain' about the time.. I
was told 3-5 day turnaround and it took a little over 2 weeks),
anyway, while it was being replaced, I ordered two 12VDC fans (1-5/8")
from Mouser Electronics.  When the charger came back, I opened the
case and cut out two holes for the fans to sit into and four mounting
holes for each fan.  Found the bridge rectifier circuit which puts out
about 17VDC, and wired the fans to that.  When the charger is peak
charging (2Amp or 4Amp.. not trickle).. the voltage drops down to
right around 12VDC, otherwise, the fans are running faster than they
are rated, so I did spend a little extra and got Ball Bearing fans.  I
added a switch that I can turn the fans on/off (I don't know why I
added it) and drilled a few more holes in the case opposite of the
transformer to draw more cool air around the transformer.  With this
configuration, the charge works FLAWLESSLY, and I've charged 8 packs
in a row without any significant heat buildup.  NOTE:  The fans only
work when the charger is running off of A/C in this setup, but it
wouldn't be hard to wire it so that they would run AC/DC.
