What do you mean when you guys say the batteries don’t last? The lower amps that come with the cheaper batteries won’t start the kart after a while or are you getting cracks/leaks on the top side also? Everyone that I talk to uses an external starter, so it’s hard to say if this vibration problem is just my kart or if this happen with most others also. I’m trying to come up with a battery relocation maybe to the front like the MY09’s use.
