Is a second battery worth it?
 

When I get my new Bit I will do some testing myself, but is the extra wieght from a second or third battery really worth the extra power?

I havent done this mod, but it is usually is for drag races. I wouldnt do this unless i had an extra chassis, which i dont. Yes, it does add extra weight, but it does mad wheelies when it starts, you gotta give that some credit :D

yep
 

the battery doesnt weigh isnt enough to really way the car down alot but it can cause it to do wheelies i like my dual cell car but its kinda hard to control and if you do do the dualcell mod wire it in series not parallel

The second battery mod is a fun mod. I love it because the car is now very fast, even with a slower motor. With a fast motor, the car is out of control :D

yeah i agree, duel cell 1.0 is wicked!
