I sent it to FMA for them to look at it.
They have reasonable flat rate repairs depending on the problem, so hopefully I can get it fixed. Then I would definitely need a second power supply to setup two charging stations, one for home and one to bring to the field.
Thanks for you help.

I am still using the 47A version since 2011, best PS money can buy, man, I bought a Hitec PS ( eFeul variety) and what a mistake it was!
I joined this Forum to buy from Feathermerchant, I just checked the year below my avatar and it says 2011.

Wow that is awesome. I can't even remember what I was doing in 2011.
FYI the now batch of 47A look to be new, not used. They are each wrapped neatly with fitted foam padding. They are clean both inside and out. Really pristine.
In the past, I have received some that are really dirty inside and sometimes a little corroded outside. If they are full of dust bunnies, I open them up and try to clean them as much as I can.

Mine was extremely clean and no hint of usage actually.
I have the bad habbit of leaving the unit plugged in and I enjoy hearing the fan purrr...
I know I am silly, but that fan is so smooth and quite, a quality trait.

Edit: it is my mistake, now looking at the picture, I think I have the 42A type.
Sorry about that.

12v 69 amp ps


So I'm going to be running a charger that needs 50 amps at like 15 volts. Will this work?

I think I just emailed you. It is a 306b and requires 24V to run at full output (1,000W).
It will charge at 500W on 12V.

I need a recommendation:

I just ordered two Revo HV 435 Blend 6s 5900 mAh batteries.

I'm about to pull the trigger on a GT500 charger so I can charge them.

I have been running Sky Lipo 6s 5000's on my Classic Pattern Plane. https://www.rcgroups.com/forums/show....php?t=1436652

My current charge set up is an Icharger 106b+ with a 12v 30 amp power supply. I charge at 10 amps ( 2c ) and I'm fine with the charging time.

Do I need a new power supply? If so, which one of yours? 12v or 24v? I do not parallel charge and I'm not a power user so I do want to buy more than I need.

Thanks in advance for your assistance.

Charging a 6S battery at 10 Amps requires:
6 X 4.2V X 10A = 250W
From your 12V power supply, that is about 24A.

The GT500 will output 250W with a 12V power supply and 500W with a 24V power supply.
So you will need another power supply if you want to use both chargers at once.
If you only want to charge one 6S battery at 10A then a 12V 47A will do fine.
The GT500 will charge at up to 20A but only with 24V input. So you could charge at 4C instead of 2C or you could parallel charge two 6S at 10A each if you bought a 24V power supply.

A 12V 47A power supply has no connectors. You will need an EC-5 to connect to the GT500.
You can buy the 24V 47A as a plugnplay model with an EC-5.
Do not ever connect the icharger to 24V. It is not rated for that much voltage.

Well the i308duo is a 1,300W output charger with a maximum draw of 60A from the power supply. So the 24V 69A power supply will only run one of those chargers to full output. I can build one with two 24V banana compatible outputs but I think the charger has an EC-5 input. Besides a 4mm banana will get pretty hot at 60A. Please verify which connector you need on the power supply and the gender (of the metal parts).

They never got around to looking at the PL8 so they called and offered me a hugely discounted new unit.

I am enjoying my iCharger 4010Duo, works quite well. Currently feed it 25volt from your power supplies. Suits my charging needs perfectly right now.
This charger can take up to 50 volts input.
In your opinion would there be any advantage to going to 36 volts (three power supplies) or 48 volts (4 power supplies).
I know the amperage from the power supplies to the charger would be lower and therefore less heat, but any other advantages or disadvantages you can think of?

As far as advantage to using > 24V, to make full use of the charger's capacity, you must input 34V.
At 24V and 65A that is about 1,560W input and so about 90% or 1,400W output. I have not had great luck with putting more than 2 power supplies in series. At least not the 75/100A that I sell.
