      That's typical of the Hyperions. How's the IR looking on your Revos fellas? Mine started life at 4m and continued to rise. Last charge cycle the measured 7m.

        I meant to reply to his post. That's impressive. ...very impressive!

          I have 4 HV 5s 4200's and they're in the 1.5milliohm range after about 20 cycles. Rising IR isn't a good thing is it???

            Will these HV batteries work with the hobbywing 180 amp ESC or is a HV esc required?

                    What are you measuring with Doug?
                    IR readings are not completely synonymous with higher quality, but those readings seem to be off by a lot either way. Mine are all sub 2mO unless they're cold. What do your other lipos test at?
                    Are these the 70C packs?

                      Should still be safe for 6S and below.

                          My old thrashed turnigy blue packs are reading 7 mO. They also suffer badly from voltage drops triggering lvc, hence getting new revo's. I just have to go through the disposal process with the turnigys now.

                            thanks I will order some for my apparition, well done on 95.6 mph I have a goal to reach now.

                              I'm using Hyperion 615s and 720s
                              I don't disagree that IR readings are not completely synonymous with higher quality.
                              I'm also certain that stated high capacity cells with high IR are worthless in high power set ups. As worthless as low IR cells lacking capacity. It doesn't matter what the capacity is if you can't deliver it.

                              The vast majority of my batteries are Hyperion. As Mike stated 100s of cycles over several years and low IRs. Under 2m.
                              2,3,4,5s packs 5-5500 35c and 5-6500 45c. Should have never swayed but whatever.

                              LNE 6000 65c, and the Revo 5000 70c? (Who really knows right? I don't believe that was ever cleared up.)
                              The IR on the LNEs according to my equipment started around 3m and are upwards of 8m now IIRC.
                              6-6000 65c, 2 with 8ga wire. 2 that I removed approx. 14" of wire from. Also have two 4s 5000s. One is trying to puff.
                              The Revos started at 3m and measured 7m at last charge cycle.
                              All of these packs are less than 6 months old and have less than 50 cycles on them.

                              I'm sure they are both great batteries. I just got some out of a less that stellar lot. It happens and I'm sure someone has similar Hyperion stories.

                              FWIW
