2 cells will make 12th and Oval, and will equal 5-cell touring. Make the Spec motor a 9.5 and it works there, and make the motor used in Off-Road a 4.5 or 3.5 and it works there.
The problem with LiPo is that at 7.4v it is burning motors out in TC Spec (ask anyone who tries to be competitive) and at 3.7v it doesn't suit anyone else. LiPo are volatile, can't be charged in 15 mins (and you were the one wanting convenience and lower numbers of batteries to carry around) doesn't deliver the amps unless you have more capacity than you need, and requires an investment in new springs, oils, suspension settings and tyres to use the lower weight limit.
Let me see now, I could invest in all that, and probably a new car, or I could buy one pack and a charger for under 100 notes and drive all day - it's a toughie!! 
Sorry Mark, but you are now the person who does not want to move with the times - never thought I'd say that!! The future is LiFePo4!!  |
go on then, if you used that argument................... explain!
do at least 50% of chargers cater for lipo?, now how many cater for a123 cells?
lipo is .2 volts higher than nimh, no motor changes needed, explain how your saying its cheaper yet you say you need to buy lower winds? your also increasing voltage on at least 3 of your mentioned classes and reducing it in off road
i dont see anyone blowing motors, unless there over gearing which will happen no matter what power source.
no go show me where im not moving with the times, lipo is here NOW, its stable and we can go there next year, as packs fit cars NOW.
if in another year the A123 are proven to work and can fit in cars/classes then yes ill use em, but i live for now, and what we have is lipo,
have you actually used the A123 cells?
