My brother has a orion 3200 lipo and he is using a Ice charger with the Novak power supply it puts out 14v and 10 amps, His charger is set to 3200 MAH and 100% battery capacity, charging at 2.5 amps he started charging it and the voltage went up to 8.4 volts after a few minutes and stayed there but then his charging amps came down to 1.6, he shut it off as soon as the amps dropped, the battery should not be charged below 2 amps or above 3.2, So is this a problem? or is that normal? we are new to the lipo stuff so any help would be great.
