Anyone have the SkyRC NC2500 charger?

Anyone have hands on experience with the SkyRC NC2500 charger?

How does it compare with the Maha 9000?

Thanks.

Just a bump as I am also interested to know ... just seems impossible to find it though.

Seems to me like a just more expensive (but colorful) version of the C9000...

It looks much better, even with Bluetooth!

I have been using it for about two weeks now ... and from what I can see it's very similar. The difference here is:

1. You can control functionality of the charger from iphone
2. The LCD display goes off after a while of charging.
3. There is a fan
4. Some of the measurements are more indepth (battery resistance)
5. Using the iphone / Android app you can change charging parameters of one / all slots.
6. Plastic stand at the back seems pretty flimsy compared to Maha's one
7. There is a usb slot that provides charging for usb charge based devices.

Where did you get it?

ru.nkon.nl is a European source for this item.

Thank You..

Got mine at www.rc711.com. These guys are just cool! Very fast and flexible.

One more thing I want to add is that the NC2500 also allows most of it's guard parameters like delta V and temperatures to be customized via the IPhone/Android app.

Two questions :

1) Is the fan always on or kicks in incase of overheating ? How often kicks in?
Does it makes much noise? (i.e. can you sleep at the same room with the charger?

2) Have you tried charging C or D batteries? Can it charge it or there is a maximum mAh (like maha 9000)

Thank you

Having read the manual last week, I remember that it has limit of either 3500 or 4500 MAH. I checked farther and it is the only factor NOT programmable !

It's like the fan on those old CPUs kicking in when you are doing some heavy processing.

My old LaCrosse charger quit terminating on one channel. This was only a *few* dollars more than the Maha, so I ordered one. Looking forward to its arrival.

Is this made in Taiwan?
Looks like OEM from Maha?

Don't know if it's oem. On build and functionality it's like a better maha

I read the manual and it says there is a Turbo fast charging - 60 minutes to charge up 2500mAh battery. Is it the case that the fan only turns on when in Turbo charging mode or it can sometimes turn on even if it is not in Turbo charging mode?
Yes, if the fan does not kick in when not in Turbo mode, then that would be great.
I don't seem to be able to find in the manual how to set it to Turbo mode. Is it user selectable? I hope so as I don't normally use Turbo charging.
Thanks.

The fan is purported to be "intelligent" and seems to just come on randomly. I don't know what algo it employs. Probably internal temperature. Afaik it's not configurable.

Thanks lowks.

For those who might be interested, I compared the specs of the Maha and NC2500 using the manuals.
Here are the differences:

Specs	Maha	NC2500
Charging current	.2 to2A	0.2-2.5A
Delta Peak	?	3-15mV
Discharge termination	1V	0.5-1V
Maintenance charge	10mA	30mA
Temp. protection	?	55-70C
Input power	12V 2A	12V 2.5A
USB power	none	5V 1A
Supported capacity	100mAh-2000mAh	500mAh-3500mAh
Battery temp	NA	yes
Battery int. resistance	NA	yes
Battery volt graph	NA	yes
Backlight	Always on	Off after 10 mins
Firmware upgrade	?	via smart phone
Smart fan	NA	yes
Bluetooth	NA	yes
country origin	Taiwan	?
warranty	3 years	1 year
default charge AA	1000mA	1000mA
default charge AAA	1000mA	400mA
Buttons	4	7

One "major" difference I noted was the maintenance charge.

10mA for Maha and 30mA for NC2500.

Can someone comment why NC choose a higher maintenance charge?
Is a lower maintenance charge better? (can leave it in the charger for longer duration)
Could it be that NC is capable of charging higher capacity cells and therefore has to up the corresponding maintenance charge?

The Maha C9000 charging limit is 4000 mAh , not 2000 mAh.

The discharge termination is 0.9 V , not 1.0V.
You can't upgrade the firmware on the Maha C9000.


Also the Maha C9000 has four separate temperature sensors. One for each slot.
The NC2500 manual says: "The charger has a built in temperature sensor".
I guess that means all slots are sharing the same sensor.
