I'm 100% sure that Lipo is the future. My question though derives from the fact that here in Europe we are using now 5-cell (hence lower volatge) not to push to the limits motors and ecs.
When using the 7.4V lipos wont be bad for ecs & motors and start to have fried one or both items?
Thank you

I sent Austin Else an email regarding MaxAmps batteries with my questions, concerns and comments and I got a 1.25 page response back. Suffice it to say, we should be seeing some info about their cells, pack assembly and safety on their Web site in the near future.
When making product comparisons, I think it's important to have as much factual information as possible. Personal experience is highly valued and does count, but as has been mentioned above, it doesn't account for the person's level of expertise, experience with other products or circumstance.
Until Austin mentioned it, I didn't realize that people were creating and posting discharge graphs for batteries (nitro guy -> electric). While it is a lab experiment, from a performance perspective, it does seem to be of some value. What do you guys think about these graphs? Are there different methodologies in use? Which one is better? Is the fact that most of these seem to be constant draw tests versus varying draw tests somewhat misleading?

We do not use hard plastic cases for several reasons. They trap the heat from the cells and cause the packs to heat up. They also do not allow you to see what is happening in the pack so if a cell begins to “puff”, you would not even know it with a hard plastic case.
It's nice that they're trying to put the good foot forward, but maybe they could do it without making things up to cast their product in a more positive light. Then again, this is the company that encourages their customers to spam R/C message boards for free shirts.

Anyone who is telling you that their cells are “safer” does not have a good understanding of the technology.
This is why disclosing the cell supplier is the most important factor. I'm not saying Maxamps is using the crap level cells. But I am saying there is a crap level of cells that I don't know if they are using.

Traxxas can choose to work with any company that they want. They choose MaxAmps.
On the safety thing:
I didn't read where they had any overload protection or fusing. You know, like the "other" manufacturer. I know that feature alone saved me from having to buy another car.
