Damaging dischargingrate ?

[Tor Rasmussen]

I'm wondering if my batteries can be harmed by discharging to fast.

I've build my own discharger by parallel 5 lightbulbs at 6V and
2.4W.
My Rx-pack (4 cells of 1100mAh NiCad) light up the bulbs, and after about
3-4 minutes the lights dimmes out.
Then I measured the pack and it read 2.20 V, and counting upwards, 2.21,
2.22, 2.23 and so on, stopped at 3.3 V.

Same goes for my Tx pack (8 cells of 1100mAh NiCad), but then I've connected
the 5 bulbs parallel to another 5 bulbs serial, so the current for the
bulbs measuring 12 V.
The Tx pack dimmes out even faster, less than 3 minutes.

Both packs were originally over halfcharged when I started.

QUESTIONS:
Do I harm my batteries discharging them this fast ?
Should I rather put in some "milder" bulbs ?
If that's the case, which bulb-specifications do you recommend ?

I bought a discharger, I think it has 10 bulbs?? maybe wrong there, but I
know it draws 20 amps. it uses 1157 duel element bulbs in parallel and has
worked fine for me. Just do not kill the batteries completly, down to 2
volts works for me.
