GP Triton charger

Why would you want to cycle a NiMH battery? Most recently mfgr'd NiCDs don't need cycling....

There is probably a diode in the transmitter charge circuit. This would have to be bypassed in order to charge directly through the transmitter jack. Instructions for by passing the diode for some transmitters may be seen at:

Yep the triton is awesome, but you very likely have a Diode tha

prevents discharge from the charge port. Just remove the battery fro the TX

I vote for diode too... prevents discharge, not charge

Cycling is a good way to determine the remaining capacity of a battery, which is a good thing to know. While you're flying is not a good time to learn that your battery only has 20% of the original capacity left.

Open Circuit means that the charger is not seeing the battery. A diode could cause that as Red has suggested, but the Triton CAN charge (not discharge, though) through a diode. You said the problem happened at charge rather than discharge? Perhaps something broke at that moment.

I assume the charger has a fuse or two inside, perhaps that blew? (I've never opened mine up.) If so, you'll probably want to send it back for repair rather than void your warranty.

Try to cycle your receiver pack, see if that works.

Well, you haven't said how you checked your cables -- it's possible that they're bad, though it's pretty unlikely.

| > Need help !!!!!!!

Well, as suggested, going back to the LHS isn't a bad idea, unless it's not so local.

Red,

He did state;

More likely an bad cell? --

Some chargers won't charge it either as they can't read the voltage the Triton won't at higher rates.

Did you remove the battery or leave it in the transmitter? If it's out of the transmitter, then it's either the charger or a bad pack. If in the transmitter, it's probably the diode as everyone here says.

Are you schizophrenic, or what? Right after this post, you make the same suggestion, and yet you're correcting Red now?

Actually, the Triton *can* charge through a diode -- it just can't discharge through it (which is to be expected.) Obviously it puts a small amount of current on the output port and then measures the voltage, rather than just measuring the voltage without any current.

Somebody suggested that it can't charge at high rates through a diode, which seems odd, but I'd suggest not trying -- running a lot of current through the charge circuit, which was designed to handle 100 mA at most, doesn't seem smart. It probably wouldn't fry the radio itself, but could certainly make sure that you have to remove the battery to charge if you fried the charge circuit. My radios seem to tolerate one amp through the charge circuit -- and I don't want to risk anything faster. If I need to charge them faster, I remove the battery.

Try charging the batter out of the transmitter. Most likely the diode in the tx is preventing the charger from seeing the battery. I have a Triton charger and its the best thing since sliced bread.

I read that as the battery was installed in the tx and he is trying to cycle it thru the charging plug. Could be wrong.

Ok . Thank for yours try to help. Maybe my English is not very good / clear but my battery trans. pack was out of transmitter. I own a Futaba 9c and the pack have like servo connector with only two wire, one red and one black. I used the regular receiver charging cable.Not diode in this circuit.

The charger is defective and my LHS change it. The new one is OK. BTY, how can I know if this one have the improved / update software ?

Thank again for yours time.

Dino

I have often wondered.... What was the best thing we had BEFORE the advent of sliced bread??

Bill

Probably the buggy whip; Because before that you had to do a lot of shouting ;-\

A sharp knife?

Well let me just correct one statement I made. Yes the triton ca

charge with the TX battery inside the TX and the Diode in place. I will however terminate that charge when using higher charge rates mine does every time. Just an FYI.....

Mike, how high of a charge rate? I regularly charge my Futaba

(including a 9ZAP that has the diode built into the removable batter itself) at between C/2 to 1C at the field without problems (or so thought). Anyhow, I would very much like to become educated before put too much trust in that aspect of Triton use.

Thank

Dino, there's only one "improved/updated software" version I know of and it is indicated by a green dot stuck on the base of the Triton. Cheers from Oz.
