Yeah, that's a good pack, but I don't think it would get me another 10 minutes of race run time. Right now I'm running the Hyperion 4350 and that is an Enerland cell too. I thought about going with the 5000 too, but still not sure that I would get an additional 10 minutes of race time there either.

sorry i wasnt clear, i mean run two of those:027:

[Sower]

Woah, that would be sweet! I would have a run time of like 40 minutes! Unfortunately my truggy would do barrel rolls in the air from all the weight being on one side. :005:

[jollyjumper]

oh i see, that would be bad.
you must have one side motor and other side batt?!?
could you change to top mounted motor and batts on both sides?

[Sower]

Yep, it's a battery on one side, motor on the other. Here's a photo of it - a little dirty! Not sure about the top mounted motor. I'll think about it.

I'm talking about Flightpower/Enerland cells:

Either 2 of these:
From Enerland website:
Capacity : 3300mAh
Cell Model: PF 6644130XP
Voltage : 14.8V
Charge Current(2C) : 6.6A
Continous Dis.(25C) : 82.5A
Dimension(mm) : 27.5 * 44.5 * 143.0
Weight : 322g


Or 2 of these:
From Enerland website:
Capacity : 3200mAh
Cell Model: PF 6444135XQ
Voltage : 14.8V
Charge Current(2C) : 6.4A
Continous Dis.(30C) : 96A
Dimension(mm) : 26.5 * 45.5 * 150.5
Weight : 342g

Edit: figured I would add the towerhobbies.com links as well...

They don't show an Evo 25 3300mAh yet, but they do have the Evo 30 3200mAh listed.

The Enerland 3200 might work. It's a little longer, like my 4350. That would be nice - basically a 4s 6400. That would easily get me through the 30 minute race. Interresting that the 3200 is heavier than the 3300 though.

I just saw this one too:

Capacity : 6000mAh
Cell Model: PF 10343150XP
Voltage : 14.8V
Charge Current(2C) : 12A
Continous Dis.(20C) : 120A
Dimension(mm) : 44.2 * 45.2 * 165.7
Weight : 622g

That might work really well!

Because it's a 30C cell versus 25C is my guess.

A flightpower 3300 evo20 4s1p weighs 360 grams,i think those figures are off or just the weight of the cells and not the pack,the 3200 being 342g seems about right though.
