yea i have a baja champ. i have a 1500 battery and it only last around 5 minutes. wat can i do to make it last longer without spending any money.

Drive off full throttle. five minutes for that battery is actually pretty good. Don't use reverse, if you have it... That's pretty much all you can do

what kind of charger do you have and what brand batterys are they?

the charger is a hobbico 900 and the battery is 1500 piranha
