I know it was asked already, maybe just missed. So, a pack like the Orion 4800, that's a 2S2P configuration (2 cells in series, derived from two pairs of cells in parallel): While it's been noted the pack shall be 2 cells in series, it leaves it open to debate.

Would a pack in a 2S2P configuration be considered legal (assuming it passes all noted tests)?
I have already asked ROAR to clarify this. My assumption is that the this is OK. The battery is made up of 4 cells but you are configuring them in a way that makes them 2-cell in terms of the legal voltage of 7.4V.

This will be Ok,
An earlier version of the draft explicitly stated that there was no limit to the number of cells in parallel. Somehow, through the multiple revisions, that text got lost. A 2S2P is legal and is still in the spirit of the rules.

Sure that will be a time known as "Before Shanchez" and a time known as "After Shanchez".

1/10 Electric RC cars are finnaly at their ANNO DOMINI.
For such a "Historic Event" we should probably get her name correct, that would be Dawn Sanchez, not Shanchez.

Dawn or other Board Members, What's with the negative tolerance levels? Am I reading that right? Why are we forcing a minimum size?
