Rx pack chargers

[GTD]

Can anyone suggest a charger/conditioner for receiver packs, one that
supports multiple packs simultaniously, preferably with slow and fast
charge rates? One that supports 2 packs at once is ok, but I'd really
like one that does up to 4. Thanks, Greg.

2 pack chargers are pretty common but I think a 4 pack charger would be
pushing the price limit for what you want it for.

MRC Super Brain 977 will do 2 packs charge and/or discharge, 1-9 cells and
costs around $95 USD. Its also a AC/DC charger from what I can tell. It
will also charger almost every type of battery.

Next up the price range would be something like the Schulze range of
chargers. The ISL6 - 330de also does 2 packs. The positive about this
charger is the firmware can be updated with a simple eprom replacement so it
will never go out of date. I think it sells for around $150 USD.

I think Schulze also do a 4 or 5 pack charger for around $900 USD.

Something else you might consider looking at is a charger that is capable of
charging lots of cells. My charger will charge 1 - 30 cells and I charge a
pair of packs for the Emaxx at the same time since the packs only get used
in the Emaxx. The only thing I do is discharge them separately.

Cheers

I was looking at the isl6-330de, and I guess I just don't understand
how these work. How can it charge 30 cells at once? Do they all have
to be in one big pack? It says the 977 will do 2 packs, and 1-9
cells, , is this each pack, or both put together? It appears, by the
connecter that they are designed for the large battery packs, is there
some adapter needed to attach receiver packs?
If someone has a link to somewhere that explains all this in detail, I
would appreciate it. Thanks.

When you say "receiver pack" I am assuming you mean a 5 cell hump or flat
pack?
I know it's not what you are asking for, but I use Traxxas chargers from the
Revo kits.
Real cheap on eBay as you can usually snag one up for $20-$28 with a flat
pack battery.
I own 3 of them and they charge reciever packs pretty fast.

When I charge the 2 packs for the Emaxx I have a separate charging harness
with a pair of deans plugs wired in series, that way the charger will see 12
cells. The problem you run into when you charge more than about 10 cells is
having a power supply that can supply enough amps and continuos volts. My
little power supply is just on its limit for charging the 2 packs @ 5 amps.

At 30 cells a charger obviously becomes a inverter since it only has a
nominal input voltage of 12 volts. So 30 cells would want a supply voltage
of at least 36 volts which the charger handles. This is why you would need a
power supply that has a output of around 3 - 4 times the charge current
needed.

Yes you would have to make a adapter for your receiver packs. My charger
has banana type sockets on it and didn't come with any charge leads, so I
just made them up to suit. I have one lead for charging the single cell
glow starter, one for the rx and tx packs, another for single 6 cell packs
or the Lipo packs, the one for the Emaxx packs and a last set for charging
my 1:1 scale car battery.

Hope that helps explain it a little bit.

Yes, that is EXACTLY what I am looking to charge.

I have that type of batteries I am looking to charge, what I was
looking for is something that could also condition them, and do
multiple packs at once.

Shouldn't be too hard to find something that charges/cycles/discharges 2 at
once...4 would be the trick...

Thanks. I was looking through TH for chargers, I just don't know if
I'm clear on it all. I looked at the Accu-cycle elite, and it looks,
if I understand correctly, much like what I need. Since it states that
each output can handle 10 nimh cells, am I correct in my thinking that
2 reciever packs (5 cell flat or hump packs) can be charged on EACH
output, for a total of 4 simultaniously? Thanks for helping me
understand all this.

That I am unsure of... I know there would be no problems with 1 pack per
line being charged/cycled/discharged on the different lines with this
charger.(total 2 packs at once)
With 4 batteries,however, obviously you would need some sort of splitter,
either for series or parallel (don't know which would be the more efficient
or correct way) to obtain two batteries for each charge channel for a total
of four... I also do not know what kind of effect this would have on the
charger.. It should feasibly work, as in tricking the charger that 2 batts
are actually 1...however, minute differences (voltage levels) in the packs
may have an advert affect in the "synchronized" charge.(resulting in 1
battery possibly being charged more than the other) I also have no idea as
to how a discharge would affect 2 batts on a single charge line.. I would
almost think that it would be unwise to try it as well,as one pack may have
a higher voltage or "more juice" than the other and possibly render one of
them unchargable/unacceptable due to too low of a voltage (overly
discharged).
Sorry I couldn't help more.
Good Luck!

It shouldn't be a problem charging two packs on the single output as long as
they are done in series (and the charger can handle the number of cells).
With parallel charging the charger see's two (as an example) 6 cell 3000 mah
packs as one 6 cell 6000 mah pack, so the charge time will be doubled. You
also have the problem of the packs equalising and the charger will most
likely false peak a lot.

With my Emaxx packs, I always discharged my packs separately and then
charged them up in series so the charger see's one pack of 12 cells @ 3000
mah, charge time is the same as it would be if I only did one pack. I only
do this with my Emaxx packs because they only get used in the Emaxx and they
are the same age and capacity.

Different capacity packs should not be charged two at a time.
