The inability to use stored paramaters on both channels seems like a silly thing to me!

The only thing that bothers me is that the supplied power supply has limitations with respect to the unit. SInce I will be charging RX packs, it is not a problem. If I has 6-10 cell packs for electric planes, then I would be upset.

Hey Giest I noticed that those limitations with the ac power source are when using both channels concurrently. I wonder if there are any limitations when using a single channel.

BTW, I assume you've received yours. What are your thoughts. Have you had a chance to charge any LiPo's yet?

No, Fed Ex is still playing with it. It has been in Atlanta since 7/2 and has been bouncing between two facilities that are less than a mile from each other. If I read the manual correctly, the limit is 14VA per channel. With that said, you can charge a single 10 cell pack at 2 amps. This would equate to about 28.5 VA total so there is not a limit.

coomarlin,

In response to your questions:

1. A safe fast charge for any size pack is 1C. Packs made with sub-C and larger cells can usually fast charge safely at 2C and even greater for the biggest packs. I fast charge all my batteries (NiCd, NiMH, and LiI) at 1C.

2. I typically use 1.1v per cell as my cut-off when discharging - it's safe. 1.0v per cell is fine but 0.9v per cell makes me uncomfortable. I tend to lean towards the conservative side when discharging.

3. Most manufacturers use C/5 to rate the capacity of their packs. So, when I discharge I always use C/5, that way I can compare apples to apples when checking capacity.

4. I would leave the default alone at 8mV. I have my Triton set to 5mV for NiMH and 10mV for NiCd. The lower the number, the more conservative the charge, meaning less damage can be done to your packs. There is a good explanation of this floating around somewhere. When you get the time you might want to look for it.

Hope this helps a bit. Good luck with your new charger!

Well, I finally received my charger today. It has been floating around Fedex in Atlanta since July 2nd. I plan to cycle a couple of packs to check it out. The charger looks good and the power supply looks to be a regulated supply with a transformer instead of a switching power supply.

I will post more when I check it out.

OK, I have had a chance to charge a few pack under a couple situations.

Charged two receiver packs. A 6v - 2700maH pack and a 6v - 1650maH pack using the 1650maH parameters with no problems. Packs were charged, flown (5 flights) and recharged and were within 100maH of each other. I started the cycle feature on both backs and found that sometime the supplied PS will give you an input over voltage reading on the charger. I am not sure why this happened. I could not duplicate it but I will continue to test it out.

I use the 6v 1650maH setting to charge a 4.8v 2700maH ignition pack. The charger saw the pack as a 4 cell pack, put in 850maH at the proper voltage 6.4 (max) and went to trickle charge at 51ma at 5.7volts.

My next plan is to program two memories and see if I start channel one on memory one then go to channel two and select memory two. The manual says you cannot do this.

Miles, are these Nimh or Nicd ? What is the peak sensitivity setting ? Thx

PS. Did you get my email on the APG html code ?

The peak sensitivity is at 8mv and all of these are NiMH's
I plan to replace them with 1700maH Nicads. I first want to test how low I can take the packs until it can't handle .8 amps at 1.1 volts per cell.

Yes, I received your emails saying that it worked!

Have you guys checked the discharge currents yet?
Please keep us posted and your final thoughts. Thinking of getting one if you all think they are working good.
Thanks

I haven't checked the discharge yet.
Today I ran my transmitter down to 8.6 volts.
It is a 1650maH NiMH pack
I put 1688 maH back into the pack before it went into trickle charge.

The only thing that I have noticed that is out of the norm is that the supplied AC supply will sometime cause the charger to say that the input voltage is to high at 17.8 volts. I will test this out more when I get the chance.

Try using a DMM to verify the output voltage from the transformer the next time you see this error message. That will be interesting to find out.

Very cool site and excellent conversation. Just got into flying and have a VG 6000 for a LT-40 with a Thunder tiger .46. Instantly hooked, went out and got realflight and have been practicing almost everyday. Have flown twice with a trainer cord and after an excellent day yesterday have 7 solo flight and even a dead stick, what a rush. Anyway, felt the urge to buy something the other day and ordered this charger for 2 reasons, because it would do both my Tx and Rx at the same time and that it would do Li-Po battereis, whatever they are, but figured if it can do all three that is a good thing. After reading all your posts i can see i have alot to learn about charging my batteries, You guys keep posting and i'll keep reading.
Thanks again.
