That's different.
1/8 require 100Amps @ 14.8V, or 1480Watt
100Amps @ 7.4V are only 740Watt (more than enough for a 1/10 buggy with a 4.5+ motor, but surely not enough for a 1/8 motor).

amps are amps, i was saying an 1/8 vehicle will pull more then a 1/10 anyday

yes, but Ampere is not a measure of power. You can't simply compare them at different voltages.

A 1/10 can pull more Amps than a 1/8.
A 1/12 pan car with 1S lipo and a high-kv motor pulls more Amps than a 1/8.

Team Orion are releasing a 45C / 4500 saddle.

They'll be available in a few days.

Any idea how much? Where can I get one? There is no info on the orion site so have you seen a preview/review somewhere?

Cheers
Luke

just change to a different motor if you dont have enough power. you wont really need to use the 35c-40c on mod, only stock. and with a 4wd, its mod so just change motor. the cell is too wide, it is pretty much a square so you wouldnt be able to fit it anywhere exept in a 1/12 scale car like it was designed to do. 1/12 uses 4 cell or 1 cell lipo so it wont work out.

Can't say when in the US or how much, but they've arrived to the distributor in europe and are being despatched to the shops. Agressive pricing I was told.

Don't really care about US availability as I am in australia I tend to find pricing in the EU very expensive, am I looking at the wrong shops? If you can find out what shops they are going to it would be much appreciated

what you also need to remember is what you increase the volts by two the amps go down. so a 1 cell lipo will need a higher "C" rating than a 2 cell.

Why not more 50C packs

Because some companies know more mugs buy cheap cells reabelled with big numbers

There is no standardised way of establishing the C-rate and it is prostituted too often.

There is a way to do it - by stating the Internal Resistance of the cell at a given temperature and then the watts (heat) per gram at continuous max - They should also state the level of match of the cells.

Or you look for independent testing and always check the constant rating is 50% of the peak - not 80 or 90% - the latter means its overated on the constant spec

There are very few makers who sell packs at an honest rating the best packs I have ever tested are the Thunder Power 40/80's hardpacks- they have half the resistance of the V2 Extremes and 1/3 less than the 30/60C ProPowers.

Only true for an equal power comparison, which requires a corresponding change in the load/motor resistance.

From a practical RC angle, 1 cell generally means a relatively light pan car, which has different power requirements than typical 2 cell RC vehicles such as an off road 4wd that I believe is being discussed.
