At 1,2 volt per cell, this equals 6 amps (Ohms law: U=RxI, means voltage = resistance x amps. So in this case it's 1,2 volt divided by 0,2 ohm, giving 6 amps).

As the voltage decreases, the amps decrease also.

Since there's no cut off device, the RT2 goes all the way down to zero volt, which is equivalent to dead shorting. Except that each cell is discharged individually, so there's no risk of cell reversing.

But that doesnt nessecarily means thet the cells like to go down to zero volts. Thus the advice of taking the cells of, when the light goes out.

Next to taking the cells of when the lights goes out, there's a couple of other choises:

The Integy SP Saddle Relay Cut-off Discharger 5A.

Or use a fast discharger like the Octane 2 in combination with a slow equalizer like this:

Discharge characteristics:
- rapid discharge of the packs cells to an defined discharge level
- automatic cut-off prevents deep discharge
- Equalizing the cells discharge level to each other
- more life-time and higher performance for each cell

Singel Cell Discharger Features:
- Automatic Cut Off for NiMH & NiCd
- 1 Amp Discharge Current
- Indication for each cell
- for packs with and without Battery Connector
- Box is usable for storage and carrying of batteries
