Field chargers?
 
I know I am going to open a can of worms but I need some help. I want to get a field charger, but I would also like to have something that could safely discharge my battery packs. What are my best options?

I like my Orbit MicroLader, and I also like the Triton that my buddy has. There are others, of course. I like to control the amperage flowing into the packs. Some chargers are "too automatic" for my liking. I don't like the idea of the device choosing the charge rate by itself.

I like my Accucycle Elite. It charges and discharges two batteries independently. Works on 12v and comes with a 110 volt power supply.

If you can afford it the triton is the best there is. It will charge everything from a 12v feild battery to lipo's to nicds.

Ive been using the Sirius charger from Peak Electronics for
about 4 years now. It is simply great. Nothing to set. No buttons
to push. No displays to decipher. Just plug it in.

It does a RX pack and your TX at the same time.
Ive used nothing else since I got it.

It doesnt discharge but a companion unit is
available for that purpose.

If you like to keep things simple with no fuss
then consider the Sirius.

I agree with Mike! The Sirius charger from Peak Electronics get a big thumbs up!
I too have been using one for a couple of years...takes all the worry and stress out of TX and RX battery issues.

No need to plan ahead to charge the night before... simply plug in (12 volt power)... finish eating breakfast... and your set to head to the field...

Long day at the field??? Easy to top of your batteries from your car's 12 volt power...

very easy to use...

Best piece of field equipment I own!! Highly Recommended!!!

One of the guys at the field swears by that one. i have used it and it is fool proof. i was steering that way and thought i would post the question. How do you cycle your packs?

RE: Field chargers?
 
simply put to cycle your battries you just charge the battery fully. Then let it cool off and discharge the battery again and another cooling period then fully charge battery again. you do two or three cycles to bring the battery pack up to full capacity.

I use the Super Test thats sold as a companion to the
Sirius charger. It reads out battery capacity directly in mAh.

Works great. Another foolproof no hassle piece of equipment.

I use the Futaba charger and discharger. This is two diffrent units, but I really like this setup. Very,very easy to use and the charger plugs into my car through the cigarett lighter plug.

that just put me over the edge looks like im going to order the sirius pro series charger. I have noticed there is a pro series plus. Would this be a better choice. I cant seem much difference in the spec.

RE: Field chargers?
 
The difference between the standard Sirius charger and the "PLUS" model
is the charge rate. The standard Sirius has a fixed charge rate of 550ma.
The Plus model has a fixed rate of 1100ma. The plus also has a small
exhaust fan to deal with the extra heat.

Peak Electronics can upgrade the Standard charger to the Plus model
for $30 if memory serves correclty. I considered having it
done on mine but decided it wasnt necessary. It would only be
beneficial if you had large battery packs to charge. Mine are all
1000-1800 mAh so I stuck with the standard model.

One other point. You cant really tell from the pictures but the
enclosure is heavy aluminum. Not plastic. Very solid and rugged.

RE: Field chargers?
 
how long do you need to let them sit to discharge fully?

XTOL 04-05-2006 09:51 AM

RE: Field chargers?
 
It depends on the capacity of the battery pack under test and
the load that is placed on it. Normally Nicads are discharged to
1.1 volts per cell. Thats 4.4 volts for a standard receiver pack.

The Peak Electronics Super Test can discharge 4, 5 or 8 cell
packs at 125, 250 or 500 ma. So a 1000ma receiver pack if
fully charged would take 2 hours to discharge at 500ma or
4 hours at 250ma.

You normally discharge at a rate similar to what the pack
would see in service. I use 125ma for receiver packs
in my airplanes and 500ma for the helicopters and 250ma
for my transmitter packs.

Nicads are so much better these days than in the past
a lot of cycling is not necessary. I do it maybe once
a month or so during the season on a rainy day and
a couple times over the winter. And as a check before
putting a pack into service that hasnt seen action in a while.
