Default RE: Need Charger

If you're a beginner who thinks he is going to continue this hobby, you should very seriously consider purchasing an intelligent charger. It will do a number of things for you that are very worthwhile. It is actually worth buying instead of a 3rd or 4th model.

A charger like the ACCU-Cycle Elite can easily charge most of the battery types you're going to use over the years. And it will tell you how each of them is working for you. And you can use that information to keep up with the health of the batteries. And that can save you airplanes. I've found two batteries in the last year and a half that had cells going bad. If they had gone bad in the airplane they could have cost the airplane.

Some chargers also make recharging much, much easier. When I come home from flying, I plug my TX into one side of the Elite and plug the airplane that flew the most into the other. And head off to supper. When I check later, the two different batteries are charged and there is a readout that tells me how much capacity those used at the field. I compare that to how much I flew them and can tell in a glance if there is something going wrong in either the airplane or the battery. It's up to me to find that out, but I've gotten the info that somethings wrong. I can then use the charger to check the battery while I look the airplane over.

Your battery is a nickel-metal hydride and would take a 60mAh output wall wart charger if you chose to buy the cheapest charger you can find. But finding a 60mAh one may be easy or not. The charger that came with your TX/RX set will probably work. Ni-MH batteries charge the way Ni-Cd batteries do. You plug them in overnight and hope that's enough, if a wall wart is what you've got for a charger. If you have an ESV you can check their capacity next morning and charge some more if overnight wasn't enough.

I agree with da Rock. getting a nice charger that will do it all now will get you Way ahead in the hobby you wont regret having it. I have a charger that will do about any battery. We had a guest this week that for got their cell phone charger ...NO PROBLEM!

That's a pretty standard battery, often used on entry level ( cheap ) helis and planes.

Connectora and adaptors are readily available that let you hook them up to better chargers as said...

Or you can make your own.

Wall wart chargers are also available for it.

I have a futaba tx and it won't let me charge with anything but the charger that came with it, unless I take the battery out of the tx. Are you saying with the ACCu-cycle Elite I can plug into my tx.?

How is it stopping you? As long as your charge rate isn't too high and causing the TX's internal polyswitch to activate (preventing charging) it shouldn't matter what charger you use.

according to futaba there is a crystal or something that prevents one from using a different charger. I have a ACCU-cycle pro series and it won't let me charge by just pluging into the tx. It has a switch for 50--125 Ma.

Hmmmmmm....

What Futaba does with their charger jack setup is to have their switch polarity set differently than some of their competitors. And they warn you to only use their chargers.

What happens is..............
Charger mfg's have a number of different cords for their chargers.
I have one for my JR TXs.
I got another one to use with my Futaba TXs.

No problem.

BTW.......... an interesting detail about that.
The wiring is opposite for those two. Plus is minus, minus is plus in the different brands of plugs. If you were to plug one into the wrong recepticle and turn on the charger you'd probably fry the TX or it's batteries or something bad. Maybe not. I've not done it, but just checked my plugs to see if it could be done.

And.................
JR plugs are such that they won't go into Futaba charge recepticles. Pretty safe and nice of them. My JR charge jack can't go into my Futaba TXs by my mistake.

What'da'ya think happened when I tried to plug a Futaba charging jack into one of my JR TXs? It goes. Wonder if that was planned or just a harmless happenstance....... hehehehe...... yeah, sure........

I'm pretty sure the two connector cables in the picture came with my Accu-Cycle Elite. I know that I had to buy a couple of others for special things, but bottom line is that there are cables available for Accu-Cycles that are marked as pictured. And the picture shows what I use every time I need to charge my Futaba TXs or JRs TXs.

I would go with the ACCU-CYCLE over the Triton charger for the simple reason with the Accu-Cycle you can charge two batteries of most any type or voltage at the same time. I did not realize how handy that would be until I bought a Triton. Also, even though I can't DIScharge the battery in my TX there is nothing preventing me from charging the battery in the TX.

And the Accu-Cycle Elite comes complete with the ability plug into the outlets in your house (as well as the ability to connect to your car battery). No extra charge.
But the Triton doesn't work in the house unless you buy an AC>DC converter.

The futaba I am talking ab out is a 6exap. I said it had some kind of crystal in it, but it is a diode that that protects the tx. I can't use my voltmeter on it either, so I have to trust the one on the tx. Maybe I am mistaken about not being able to charge the tx battery when it is still in the tx. At my age I get so confused. Now what were we talking about?

What the diode will do is prevent you from using a discharge function of the charger but it won't prevent you from charging.

Default RE: Need Charger

i went out and bought a prophet charger for nimh and nicd. it works for 4,5,6,7 cell batteries.

good price, but sad part is that this is the only battery this thing can charge. my other is a lipo for by blade cx2 and the other battery i have is an 8 cell. dont think i can bother trying to charge 8 cell on it. as it says 4 to 7. but is it still possible?

The diode WILL prevent use of a meter or discharging through the external connector. Using the proper connector connected to the proper polarity and at a reasonable charging rate, any "regular" charger should function. A charger that needs to "detect" the battery voltage will NOT work though because of the diode. These would be called "peak detection" chargers I believe but don't quote me on that as I haven't used one of those.

I charge mine all the time with the Hobbico field charger and the Accucycle Elite and they are both peak detector chargers. The Elite even reads the voltage on the transmitter battery. I use these chargers on several different Futaba and Hitec transmitters. They all have the diodes

Exactly so. I made a little "Y" harness that plugs between my battery and the jack inside the Tx with a charging J-plug hanging outside for my Futaba 6DA. That way I can bypass the Tx circuitry and discharge/charge the battery using after-market chargers. I haven't monkeyed around with my 9C. I just pop the battery out when I want to discharge or cycle it. I'm running NiMH packs in that Tx and they're not so sensitive to memory so I usually just keep a float on using a daily timer and the wall-wart that came with it.

I have a Hobbico Accu-Cycle that I like but for just routine charging I rely on the less expensive Hobbico Multi-Chargers (they will do four batteries at once) and hardware-store HD appliance timers.

Hitec and entry level Futaba radios have diodes in the charging circuit tha prevent using a voltmeter to check voltage. They can easily be bypassed to use chargers that detect charging activity by sampling what's in the battery. I use a Siruius charger and have "jumped" all the diodes in my transmitters. If you go to the Peak Electronics web site or do a search for Sirius Chargers, you can find a link to the diode sheets that explain in pictures how to do this. I am now using a futaba 9C that does not contain a diode.

DaRock-- in an earlier post, you mentioned using a volt meter to check the battery capacity. My voltmeter will put a load on the batteries but will only read the voltage, not how much is left. The only way I know how to do this is to discharge the battery and see how much has been used. I know some cyclers will do this, but i don't know how to check capacity with a volt meter. Am I missing something?

No they don't read capacity. But the couple I've used over the years had faces that showed the voltage reading within a range marked in a color swath. And the location within the swath was supposed to suggest the capacity. When a 4.8V pack for instance is fully charged, it's voltage will read appreciably higher than 4.8V. When that pack has more than half, and usually more than 3/4 capacity, most ESVs will show a reading over 4.8V. If you were to use an ESV as I was suggesting, you'd not have a capacity readout, but you would get a clue if the pack was more than half capacity or not, which was my point. I should not have assumed an understanding of the method in that single sentence, but did. You didn't miss anything. Voltage readings are not capacity readings. But can give a rough estimate of capacity above and below half full.
