Have been running SMHs since May. Keep them on a strict diet of 4.5A @0.03v delta and they will be fine! Very happy with my SMH so far. Had they have been the old Sanyo 3000s I would have replaced them twice already!

dcracer: you know, i accidentally found that out a couple of weeks ago. i forgot to put it back from 4 cells to 6 cells and it still charged fine. i was using 9mV/cell or 36mV/pack though. i'll try the 24mV/pack when the rains stop.

i will be getting new batts soon. and maybe a new charger. if my wallet allows me to.

i charged my 6-cell nimh batts today using the following settings on my old (pre- version 1.2) millenium:

4 cells, 8mV/cell, 32mV/pack threshold, 4 amps, no trickle.

the capacity went up to 2800+ mAh. but the voltage went up to 10.26.

the batts were cool to the touch.

I was intrigued by the ad and price of MRC's new Super Brain 959 because it can do NiMH and NiCad batts with a digital read out and most of the bells and whistles of the much more expensive chargers. And it doesn't need a separate power supply. Found it for only $45 (retail is about $65) so I'm going to give it a try. I'll let you know how it does.

The 959 should be great for a "sportsman" racer, who doesnt want to spend the money for something a little more. I had a 809, and it was a great charger for the price, with the 959's adjustability, it will only be that much better.

spider -- I just received the 959 today and won't be using it until this weekend.
Saw a review in the new RC Car magazine - -was well reviewed by them; the only downside being no internal fan.

turbo 35 users:
when using the discharge mode, what is the ideal internal resistance value for 6-cell sanyo 3000 packs? is a lower value better? mine read between 45 to 50. thanks for any info.

Ideal IR for Sanyo 3000 : 25-30 for new battery. and yes, lower value means more punch. You must use Turbo35's cable data for more accurate number.

Stay away from the MRC SuperBrain 959. It gets hot easily and on my second use today it started to smoke. I even put a portable fan on it. Back it goes to the store.
