I have a 150lite, that is still pumping 15 amps into our bank in the early part of float, and take three hours in float to come to stable current.
I have the latest firmware 1370 andb the latest local app. It has no minimum absorb setting. And no sign of any varimax settings that are talked about in the video:

Rossw's linux utility is able to write to the classic so thats maybe an option.
FWIW, the modbus register for min absorb time seems to be set at 30mins.:
peter@atom:~$ ./newmodbus 192.168.0.223 4153
ID CLASSIC
ClassicTime 18:07:28 15/07/2013
4153 1800 (0x708)
Id be grateful if somebody would be able to tell me how to tweak the absorb in the lite?

*IF* that's the correct item (and from Bob's document it describes it as Read/Write, Minimum Absorb Time, seconds (normally unused now), Minimum Absorb time when VariMax is used. Otherwise, equals 0 - so looks hopeful), you can use my utility to set it.
./newmodbus 192.168.0.223 4153=1000 (or whatever you want, in decimal) should write the data to that register.
If the Varimax current is set to greater than 100 amps, (usually 101), then there will
be NO minimum absorb time adjustment. It will be controlled by MAX time only.
In the case where Varimax is greater or equal to 101, the minimum absorb time
is ignored. This is the suggested mode of operation.
The VariMax modbus word is divided up into two bytes... One for the Varimax Current,
normally 101, and the other byte is the minus relative absorb voltage necessary for
the minimum absorb time to start counting back up. So, in Varimax mode, the
current out of the Classic must be greater than that Varimax current AND also
the battery voltage must be less than the absorb voltage set point MINUS the
relative Vmax voltage (good to -25.5 volts).
I suggest using the normal non-Varimax mode and just let the
absorb timer count down normally while battery voltage is at or near
the absorb set point voltage.
All voltages are temperature compensated voltages if the sensor
is plugged into the Classic.
