I have several batteries for my T-maxx starter and sometimes there isnt enough juice to start the car but still some power left in the battery and I didnt want to get a memory in the battery so I was wondering if anyone has any good ways to discharge batts.
 
My roommate's been using the same battery in his ez start for over a year and had no memory problems nor has he ever discharged the battery fully. My personal fear is with NiCD's is undercharging vs starting at halfway and working your way up to full charge. I've been also using 6 cell batteries in my electric rs-4 for over a year and followed the same guidlines and have not had a problem.
 
well....ideally you should discharge at the same rate as the batteries mAh. if you have a 1200 Mah battery, discharge it at 1.2 Amps for one hour. I/ve read that a good way to rig your own discharger is to solder a battery harness to an 1157 automotive bulb. You can get one at any auto shop for about a buck. You may even have one laying around the house. I haven't done this yet myself, but I run nitro and haven't gotten to modifying my RX batteries. There's a great article in April's edition of RC Nitro. You should check it out. There's a T-Maxx VS. Monster GT article too. T-Maxx one the shootout (even though Car Action editors and journalists play the flesh pipe)

To keep optimal punch in electric batteries, you need to discharge them at a minimum of 20 amps. If you solder 10 1157 bulbs to two peices of brass tubing or something similar, then you just wire a dean or Tamiya connector to the end, plug it into your batteries until the bulbs start to dim. When you click your easy start on, it pulls much more than 1.2 amps out of them and batteries perform best if discharged at the same rate they will be used. I discharge my mod motor batts for my B4 at 30 amps each time and they have incredible punch.
