i wana change to a li-po type of batt. so where can i go get it and how much is the cost together with the charger for the li-po batt? thanks.

Well, Lipo you can get from Mack, the E-techs.

As for the charger, it depends on your budget, but I would suggest a good one that would be safer and last you longer.

Mack also sells Apache LiPo charger, which is quite highly recommended here.

I also need some help. How long should I charge nimh 6AA 1500mah if I charge with fast charge. my battery only last for about 20 min when I use it to play full throttle on a stock car.

It pretty much depends on the output of your charger. If it's 1.5A (1500mA), charging will take 1500mAh/1500ma = 1 hr. If it's 1.0A, charging will take 1500mAh/1000mA = 1.5hrs. If it's 3.0A, charging will take 1500mAh/3000mA = 0.5hr. And so on. This charging time is true only when you have dumped your batts, meaning when you noticed a significant slowdown in performance.

20 mins play is very good for 1500 batt.

When you progress to better cars, you may want to consider a better charger, peak charger.

Hope it helps.

Cheers and enjoy!
