NiMh and NiCad field charger

Post by Flierb » Wed, 15 Jan 2003 06:38:08



I am looking for a field charger (for NiCad and NiMh should have said that
the first time,) that will charge at least two packs and
preferably 3 packs at one time, it would be for 2 flight packs plus
ignition, wonder what seems to be the more popular chargers for use at the
flying field. I would not need more than 2 amp capacity per port but would
need 5 cell ability, would prefer max adjustable charge rate and peak detect
plus trickle. A nice option would be a readout that tells how many milliamps
was put into the packs.... this is probably asking too much though!
Thanks

Bill

Bill,

I just picked up a Hobbico Field Charger that will charge 1 - 8 cells,
adjustable from 200 ma to 2 a.  It will charge Ni-Cads, NiMH, and Li-ion.

Tonight at indoor electric flying, out of 10 of us there were 6 of these
chargers there and they were all busy..

Good Luck,

It is asking too much. That beast doesn't exist yet. The closest you
will find that has all the capabilities you described is the Alpha 4,
but its hard to get and limited to 1amp. If you go the other way, you
can find a two port charger, but it will be limited in a few others
ways.

Then finally, you can get everything you want, but in a single port
charger, such as the Super Nova or similar.

And finally, if you are willing to spend big bucks, you cold get
everything you want in an industrial charger, but it would be
expensive, and overkill.

I don't underrstand the requirements exactly, but some of the Schulze
range will definitely do 3 packs at a time, with enough computerised
gimnmickry to probably do what you want.

Yes, I forgot about the ISL 6-330d. Sells for about $200, and provides
for two port charging. It has a terrible user interface and
programming input setup, but can do most of what he requires.

Worth consideration.

That sounds just about right for me too, at the flying field it looks like
this for me:

I arrive with everything charged and ready to go (but has probably forgotten
the sunglasses or the kids or anything else not directly flying related)

I fly my first pack empty, changes to my second pack, putting the first on
charge and keeps on flying...

The second pack get's empty, but the first one isn't charged yet, so I want
to put that one on charge also, and the first one will be charged after I
had my coffey...

Now the first pack is fresh, and last's about to the time my second one is
filled, but now my tx battery is low, and I'm all out of coffey....

Either I need a multiport charger / multiple chargers or a bigger coffey
bottle.....

Hmm. I was thinking of one of thoe. 'terriblle user interface and setup'

Well no change there from my Futaba TX then :)

Hi,

I use the FMA SuperNova 250S peak detect charger -
http://www.fmadirect.com

I also get to the field with 5-7 packs charged, and I then rotate my
discharged batteries through the charger, one at a time.  The unit has
only one set of outputs, so I can only charge multiple packs via a
harness - something I rarely do.  It only has 12V inputs, it can
charge NiCd, MiNH and Pb batteries and has storage for 10 battery
profiles.  You can have it discharge and charge, but not JUST
discharge.  It will discharge at up to 3A and it offers charge rates
between 0.1A and 5A for up to 25 cells.  It will trickle charge a
battery if it is left attached to the output leads after charging.
The unit is small (5.71x3.62x1.57 ) and has a small fan for cooling
and is very convenient for field use.  The LCD menu is not very
intuitive at first, but you can get the hang of it after a few uses.
I paid $108 for mine at an electric show in Northville, MI, in July
2002.

I believe the Dymond Super Turbo Charger (http://www.rc-dymond.com) is
the same basic unit (I spoke with the firmware developer once at a
show) but in the Dymond unit they have surfaced a few more features
such as settings for Delta Peak Sensitivity and Trickle rate and you
can have the unit charge and then discharge.  If these features are
available on the FMA SuperNova, then I just haven't yet found them.

As I get more into flying electrics I may look into one of the better
chargers such as the Schulze, etc.

Good luck,

Ken
