i have the insane motors in my mini LST 2 and i was wondering what would be the best lipo battery fastest and longest lasting they can handle??

The first thing i would need to know is what speed control are you using and what motor(s) are being used. Most brushed based systems will only handle 7.4v lipo batteries in the mini category, mini being 1/18 and below electrical systems. If you you are using a brushless system with the MLST, than you would be all right with something in the 11.1v range, but with that much power you might have some gear and drivetrain issues.

I would suggest a 7.4v 2100mah lipo from commensense RC, it's fits very well in the battery box and will provide enough power to go pretty fast. 11.1v lipo batteries will be faster, but will not fit the battery compartment very well, but it can be done for sure.
