MMM, MAH and X1-CRT

[Jammin]

I JUST BOUGHT 4 MAXAMPS 5S 3000MAH PACKS FOR MY BL X1-CRT, I DON'T HAVE MY MMM YET SO I CAN'T TEST THEM. WILL I SEE ANY SPEED DIFFERENCE BETWEEN MY 3000MAH PACKS AND A 5000MAH PACK?

THANKS

The voltage gives you horsepower and the MAH tells you how long it can give power for.

A 5S 3000mah pack gives the same amount of power as a 5S 5000mah pack. Just the 5000Mah pack will last longer. Both are 18.5 volts.

One of the differences is the extra weight.

If they're both 20c then the 3000 will probably drop voltage a bit more since they're rated to 60 amps, and the 5000's are rated to 100 amps. I would think 20c (according to maxamps) 3000's would be a bit stressed in a truggy, even with 5s.

Double up the packs - CRT really supports a rotated diff with twin packs at the back...

5s 6000mah... no issues with bats then...

I had a 3000 5s maxamps pack. It could not handle a c50 14l in a ls10, so I would say that a pair of them in parallel would be required for your truggy.

If only it were this simple.

Votlage X Amps = Watts = Power
~746 Electric Watts (assuming a power factor of 1) = 1 Horsepower

Higher voltage allows for less amps, which give you more efficient power as less power is lost to heat across the resistive load of your setup (ie: internal resistance of batteries + ESC on resistance + motor resistance). The more current that flows the higher the voltage drops across eac component of the resistive load (this is why you see batteries drop voltage as the Amps go up).

To the point of the original question - you will probably need to run 2 pack in parallel. Obviously depends on the setup and particular motor you are using and the speed you are geared for as well.

i'm going to stick with the single pack set up. We'll I guess they'r for sale then. I'll put the info over in the general dissucion section. Pm me if interested.
