I discharge my NiMH's to 5.4v.

DO NOT discharge NiMH's to 0v (which is what some equalising trays will do), it will damage them.

Discharging NiMH batteries is good for them. It is not necessary like NiCD cells, but its recommended. After every battery pack i discharge mine down to 5.40v. At the end of the day i usually put 200 seconds or so of charge back into them. Next time i use them, i discharge them down to 5.40 v again and charge 'em up.

They will keep their performance much longer if you do what i said in the above. And yes you will notice a difference, packs that haven't been discharged i've noticed are a bit more flat on the track.

No....not if you intend to recharging them again that day...but if you store it for a week after you have trayed it...then they will die quicker!

I just bought an LRP discharger, which discharges to 5.40 v.

Costs around 11 Pound.

Chances are that one will forget to watch sooner or later.... why risk pack life? You'll just have to ruin one pack, then you could have payed for a good discharger. And as a bonus, you'll save a lot of time.

I'm using the same procedure. except that once in a while, I equalize my pack right befor a charge / race.
