Did you just use the original nicad battery came with the car? If so, how long did you charge the cell with a separate charger to get the 20-25 runtime everytime?

I am sorry, it was 180 sec, of course.
I am sure the battery is put correctly, ’cause the first run time was more than 20 min, then dropped to 7 min. And I tried to replace a new battery in the control not the car’s one. I charged the car for 3 consecutive charge, and I got only 3 mins….it’s so strange, isn’t it?

Anyway, thanks for your help?

Have you made sure you have good batteries in your controller. If they are weak it will not charge the battery fully
uA 🙂

First, I also thought of this issue. So I changed it with new batteries, and charged it for 180 min, just for a 8 min run time.

I am just wondering if you have the same case, if not, can you tell me where you bought the battery. I bought it from QFM, http://www.questformadness.com/, at that time they only sold the 120mah battery just before the X’mas.

Once again, the first 2 times was very good, the run time was more than 20 min. I was so satisfied. However, it dramatically dropped to around 7 to 8 min afterward. Eventhough I charged it for 180 min, it only reached around 8 min.

Does anyone have the same case? Or do you think they are defective?

I have a question and hope someone can help me. I bought the 120mAH from QFM. I got a very good run time of more than 20 min at the first time of double chargeing for 90 sec.

However, the running time reduce to 7 to 8 min subsequenctly after the new battery being used, let say from the second double charge.

Can any bit-char experienced car owner give me some idea? Is the battery they sell defective? I actually got 2 batteries from QFM, and both of them happened the same case.
