The reason I'm saying this is because I have been actively testing Lipos and I can see a difference in performance and changes being made frequently. I have tested packs from leading manufacturers and they range from 7.06 to 7.28 in average voltage and 12.0 to 8.6 in IR at 35amps. SMC is working closely with a manufacturer of Lipos and we have seen that they can improve there packs fairly frequently and once Lipos become legal for racing I'm pretty sure we can get the manufacturers to make special Lipos suited for racing with more power. This will most likely be at the expense of reliability and price but in the end racers will buy the best and most powerful Lipo pack so it will be the same issues as NiMH and probably worse.
Lipo (and brushless) isn't going to ruin electric racing-it's going to save it! The problem with NIMH batteries is that people can ABUSE them to gain an advantage-and they do.What's the difference in horsepower between a NIMH pack charged at 5 amps and one charged at 10 amps? It's huge! What's the difference in horsepower with a Lipo pack charged at 1C and charged at 2C? NONE!
How long are the "good numbers" good on a nimh pack? A few cycles if you don't abuse them. How long is a nimh pack still good enough to be a "race" pack? Not very. How long are the numbers still good on a lipo pack? No one knows yet because they have only been using them for a COUPLE YEARS!
How many packs do you need when racing with lipos? Two per car MAX and you can get away with one because they don't need to be peaked to deliver good power.
How many discharge trays do you need to own when racing with lipos? NONE!
Yes of course they will get better-IT'S TECHNOLOGY-and progress marches on.Sub-C nimh batteries (and brushed 540 motors) have been pushed to the edge of their potential and have become fragile,disposeable,junk.Lipo and brushless are at the beginning of their development curve and it's going to be a LONG time before your "doomsday" predicition has any chance of becoming reality.These new advances are making this HOBBY what it should be for those of us out here in the "real world" (weekly club racers that do this for FUN and never go to the "big" races). A stupid little toy car that we race for the fun of it should'nt have the maintenence cycle of a top fuel car like they do now with the old tech. I can safely say that I speak for a lot of people when I say "I've had enough and I'm just not going to take it any more". If I can't run brushless and lipo-I won't race.Period!It's too late-the genie's out of the bottle-we've seen Paree-we've lost our virginity and know what we've been missing. It's the future-it's the reality you have to deal with.Accept it,adapt to it,and survive-or go the way of the dodo,the nightsoilman,and the ice house.You're not going to make any friends,or earn any respect,trying to scare people off with BS about how it will be worse than it is now.It can't be! And don't forget that .001 volt only makes a difference to those running stock and 19 turn at very high levels of competition and very high levels of traction.What about all of us running mod on the dirt?
Right now local tracks are in the process of allowing lipos.A year from now they will be in the process of REQUIRING lipos-because nimh's leave the door wide open to poor sportsmanship.
