Lipo questions

[rcjmaxx]

While we'er waiting I have more questions.I've been asking around at local hobbies shops about a lipo setup for an Emaxx,but with very little success.They either have no idea or are strongly against it.I understand the dangers involved in both charging and bashing relative crashes but the extended runtimes and lightweight keeps me interested.What little I've learned is a company called ThunderPower makes a Lipo pack that has a built-in device that cuts the power before the cell runs down to low and damageing it self otherwise there is a regulator that can be bought and manually added to the pack.Is this accurate?
