I had already ordered a 150Mah NiMh battery, but after reading TinyRC's post about charging with a peak charger, I started chargeing my stock batteries for 3 cycles. (2min. 15sec.), and was getting great torque, and 10-15 min. run times. So when I received my 150mah battery, I was in no hurry to use it.
Today I finally decided to use it, but wanted to make sure I was using it to it's potential. So I took the charger that came with my clone, pulled the timer out, and one of the AAAs, so that it was just 2 AAAs wired straight to the charging base. I monitered the voltage while it charged. It bobbed between 1.75 and 1.8 volts, then after about 5 or 6 minutes, it suddenly dropped to 1.70, that's when I pulled it off. I checked the battery, and it was good and warm like a properly peaked battery should be.
The results:
With a 3.2 motor, and 9.86:1 gearing, it ran for 40 minutes. For the first 20 minutes it spent most of it's time on it's roof. The power was incredible. I was lucky to keep it on 2 wheels going through turns, but it usually ended up flipping. After the first 20 minutes it ran for another 10 like normal, and then another 10 slow minutes. Not bad for a 5 min. charge, I'd say.
If you've got a volt meter, try it. Heck, I paid less than 20 for my digital meter, so if you don't have one, get one, they have many uses.
