V balance problem

[Sylvester]

Hey guys i have a problem with my v balancer, im using a duratrax ice charger with the appropriate power supply.

When i plug my 4s 5000mah flightpower pack into the v balancer it shows that i have a low voltage warning (red bar flashing) but when i check through all the cells on the menu they all have 3 bars for all 4 cells. There is no low voltage yet the balancer wont let me stay in link mode since it is detecting a low voltage??

Any help would be great!
