did any of you guys here encountered over voltage while charging?? it cant charge my batts.. as i hit the charge it will say over voltage.. all of my packs... but in other charger the batts are ok.. what do you think??

Make sure that you have selected the right number of cells to charge

Try the factory reset, hold down the left key for 3 seconds then scroll up and confirm 'yes' to 'factory reset'. Make sure you have the number of cells set correctly for each of the charge options.
Before you connect a pack of cells the voltage reading (top right of the screen) should be showing the input voltage of the power supply, then when you connect the cells up it will show the battery voltage. If these two readings look OK, you should have no problems....
If problems persist, maybe try another power supply before contacting your local Muchmore distributor.
Hope this helps.

yes i tried that also sir.. but no luck in charging.. it has a power supply voltage, and when i clipped my batts the volts of the batts will display.. and all cells are set correctly according to the cells that i will be charging.. still same error.. just trying to charge again but no luck... its weird..

If you want to see how the current decreases, just watch your battery. Its also good to check on it if you have limited time because when the charge current is very low you know that your pack is nearly charged, and depending on your needs, you can probably disconnect it before its fully charged, so that you may use it.

As you can see the current limit (what you set) only comes into play when the pack is very low, so when your pack is only accepting .7A its signifying thats its low but not fully discharged.

Hi
Is it normal for the 2 fans in the charger to turn on and off individually? One of the fan in my charger is not running.

I am a little anoyed with the noise my Cell Master makes, because in Winter we run Mini-Z in a quit small place and people started to moan about his noise. The fans switch on as soon as the charger starts to charge (is this normal, shouldnt the fans switch on only when the charger has reached a certain temperature?). So today I opend it up and tryed to isolate the fans from the housing to make the noise less anoying, but that seems to be quite difficult. But i saw that the fans are connected with connectors to the print board and can be undone. So my question is what charge current will be ok for the charger with the fans disconnected? Is 4 cell 1A charge safe? Will 6 cell 4A be definately to much?

I don't recommend removing the fan. That will void the warranty.
