I have a Volcano EXP Pro, and the stock battery lasts maybe 7-8 minutes. Is this normal? I understand from this forum most of the time you need to update to LIPO' s being the best. I have looked at so many batteries and chargers my eyes are spinning. 7.4 5000mah batteries from $20 - $200. Charger/balancer from $30 - $300. What do I buy??? Can anyone one please help??? I don;t want to spend a fortune just have something that works good.

Do I need to change ESC, and do I need to put some kind of shutoff thing because of the LIPO? As ya'll can tell, I'm new to this stuff.
