Intro, I am 33 years old now. I used to race electric RC cars about 15 years ago. So I have been away for a very long time. My wife got me an electric volcano for christmas, which looks like it will be some fun. The truck is on it's way to me, I don't actually have it in hand yet but I want to get a jump on some stuff. My questions are :

1 Can the battery be upgraded voltage wise (maybe an 8 cell 9.6 or 7 cell 8.4 ?) or should I stick to a 7.2 and just go higher mah ? Would a voltage upgrade serve any real benefits ? Is it safe ? Sorry if this sounds like a dumb question, but these types of mods did not really exist 15 years ago.

2 Any recommended upgrade parts right off the bat ?

3 I am looking for increased speed and runtime with cost in mind.

All responses, help and guidance greatly appreciated. I am really looking forward to getting back in. They are building new houses across the street and there is some awesome dirt piles and stuff to tear up. Can't wait.


Thanks to all,
Chris
