Orion Kokam have been the most proactive, and transparent. And in educating the care and safety of lipos in general. We were all lucky to have an introduction to lipos like what Mr. Black has taught us. Any one who would deny that Orion Kokams are the best is going to play hell trying to prove it at this point. But they will all claim to a higher quality. The future will weed out the bad ones. Whens that last time you saw a Sanyo at the track.?
In performance I can speak only of Max Amps and Orion. So far they have both been flawless in performance, but the wires dangling are not holding up very well on the Max Amps. They really need a plug system Like the Orions, even if theres no case. Or better insulate the wire where it comes out of the shrink wrap. I see a dead short out coming, if you don't really keep a close eye on it.
Now with all that said. With all the mah's I can get from Max Amps I'm willing to deal with it same as cutting the burrs of parts from a new kit.
Now if these new Velocity Packs Have a fuse able link like Orions. I would say these are very close to the best out there. Just for the design alone.
But if they perform like a Sanyo they will not be around any longer than it takes for a about 100 bad hits on RC/Tech. In part if any lipo is really a problematic battery, it wont last as long as any Sanyo pack did.
Now thats just one persons opinion base on ones own experience.
And one more thing. WE NEED TO QUIT BASHING ANY AND ALL LIPOS FOR ONE REASON OR THE OTHER TILL THERES A REASON TO DO SO. WE CAN NOT PREVENT AN ACCIDENT, WE CAN ONLY BE AWARE OF ITS POTENTIAL.
