Help for charger!

[virusss]

Hallo boy i have a question I wanted to change my Astrflight 109, with a Duratrax ICE, do good?
I wanted to change the astroflight because many have said that not is a real CC/CV to me

I use with 4S 8000 Mah

The ice will be fine, but if you want a REALLY good charger for the money get the Superbrain 989 ; comes with a power supply too! :)

I am italian, in my country the voltage is 220 not 110, the built in power supply is not ok for me

Oh, same thing i had when i was in Europe (Poland), if you have a voltage regulator (simply plug the original 110V plug into regulator, and it plugs into the wall.)

Other than that, the ice should be fine.

Thanks for the info sylvester, i have already a power supply 25 Amp,probably that I will take the ice. :)

From what I've seen of a few chargers, not many are true seperate CC/CV units. Usually, they are adaptive constant voltage or adaptive constant current. Or maybe a CV supply with a current limit (which is the charging current).

Adaptive CV means the charger is a constant voltage source as far as the circuitry is concerned. The CPU monitors the charging current and adjusts the voltage to keep it within the set charge current value.

Adaptive CC is basically the same idea but reversed: The charger is a CC source circuitry design. The CPU monitors the output voltage and adjusts the current to keep the voltage within the 4.2v/cell mark.

Any of these designs are perfectly fine providing the CPU reacts fast enough to any changes in either current or voltage.

It's hard to tell which one is which. For one thing, the displays usually have a delay which helps even out the true C or V readings of the battery. Or the display has some type algorithm to average the actual readings to provide a more stable display. You'd need a current meter and voltmeter hooked up simultaneously between the battery and the charger to really see what is going on. And even then, if the internal CPU is fast enough, both the V or C output will fluctuate so little than it can be hard to tell without reverse-engineering the unit.

Anyway, just my observation and my $0.02...

If you look on SPEC's http://www2.towerhobbies.com/cgi-bin...&I=LXLTW4&P=ML
you will see that PS support 240V voltage so it may work in europe.
I allready bought it so waiting when it will be shiped so i will tell is realy supports european voltage

Ettore;

Robbe has got this great new charger.. check it out on robbe.com with their balancers, you can monitor each individual cell.

Wow thi robbe charger seem very very nice...
The only bad point is price 250euro ;)

I thought i've seen it for around 175-200?
