Default help my scx10 go lipo

i want to try lipo's in my scx10.

1. iv got the ea-2 esc can i program it to lipo cut off and run both lipo and nimh without changing settings?

2. hard case or soft pack lipo? does it matter? whats the deal?

3. 20c,30c,40c whats this mean? wich one do i want?

4. the lipo's im seing are 7.4v my nimh are 7.2 im guessing this is of no concern ?

im looking at the gens ace lipo's are they any good? i can get a 2s 5000mah for about $35. they offer one with plug wires and one without for $1 more . am i missing something there?

sorry for the silly questions im sure this is all common knowledge here but im lost.

1. yes.
2. whatever will fit.... Hard cases are 'usually' ROAR approved race packs, soft packs were initially used in helis, but can now be used anywhere, except on a race track.
3. C rating is constant discharge current capacity of the pack, a 1500mah 20C battery will discharge a constant current draw of 1.5x20 = 30A.
Burst rating is max current output for 10 secs, so a 30/30 C 1.5A battery will give you 45A constant and 90A burst
4. A single LiPo cell is rated at 3.7V (1S), a 2S pack is 7.4, a 3S pack 11.1V.

GenACe - that pack is a full size pack, depending oin how your car is configured itr may not fit.
I use the Hobbyking 2200mAh, 3s packs.

Questions are only silly if you ask the same question 3 times.

When shopping they usually have measurement listed so just measure what you have for room before ordering.

awsome! great information. if i understand this a 40c lipo is probably more than i need and would be a good choice so as not to strain the battery right?
