      They weren't available yet when I ordered them.

        I've been playing with the GP graphenes at our puddle. No real amp data. Just hands on running and playing. Bob asked me to put a hurt on them. I put a pair of 5k's in my P mono and tabbed it wet for 7 laps on a really hot setup. Motor wires were shrink shredding hot. It was 89 degrees outside all day. Surface water was warm. I managed to get the batteries up to 91 on the gun. I still have a lot more abuse to put them through. I'll be trying to hurt them some more this week. So far so good though.

        I have a hunch that all these new graphene cells regardless of manufacturer are going to perform better than we're accustomed to. Just better transfer of energy. Sure would be nice to be able to use them at say even 50c without them puffing a charges later.

          This is such great news to hear! Mine came in today! So I'll be testing some in the next few days and possibly selling off what I have really cheap. I like to rotate fresh batts anyways because I like that last 1mph lol

                I tried some experimental HV cells and they fell off in my limited mono of all things. Power loss was noticeable when I got down under 20%. I was only charging to the legal limit though so I suppose that makes sense. If my EOS is saying 17% I'm actually further down into the charge than it appears. The EOS is looking at 17% of 4.2 instead of 17% of 4.35 which is the max for the cell. My LVC is kept very low so it will run until the cell pukes it's guts out.

                The graphene didn't fall off that I noticed. Limited is a pretty tame setup though.

                Now that I think about it......does anyone know how the EOS is calculating that % it tells us? Makes sense that it's all voltage based but what range? 3v? 3.3v? I don't have a clue. We all just read 20% and say okay dokay. Even the hyperian chargers tells us a charge percentage as they fill. Based on what? Feeling pretty ignorant.

                      First impressions. They are a tad thicker than my 435 5000's in the same cell count. Mainly because they now have some sort of plates inside the shrink wrap for protection. Weight, well I didn't weigh them because I don't really care lol. I'm not planning on ripping one apart like that guy did in that YouTube video...from what I've read you would t see any difference anyway lol.

                            12 lipos :| you've got issues man lol.

                            (not in a bad way, of course)

                            But seriously. 12 lipos geez lol

                              Lol. That's not all what I have. I have more on the way too! I had already sold some also that aren't shown. But really.....my collection pales in comparison to most of these guys on here that race.
