I'm very new to RC. I bought a traxxas blast for our pond. I love it. Battery question, is there a stock available that offers more run time? I've looked and can't figure out what to buy. Also, what battery charger should I buy that will charge my traxxas 7.2v 3000MAH battery or the longer run time battery (if there is one) faster. I want to stay stock approved upgrades to avoid maintenance and problems. I would appreciate any help and advice. I run this boat on our 2 acre pond. Thank you.
