Need help on picking lipos?

[Brooks]

Hi there

I have just bought a Losi 8ight 2.0 E Buggy and i need some advice on lipos. I am reading Marvins Brushless setup guide and it has been very useful but am still unsure on what Voltage to run and capacity. I am going to be racing at Nene Valley which run Duration of the A final is 30 minutes, the B final 20 minutes and all others are 10 minutes and http://coventrymodelcarclub.club.off...m/default.aspx .I think i should make the B final or maybe A final so i am looking for a lipo to last around 30 mins. I have been looking at the new Ansmann Xirius Pro lipos:

If you could offer any advise on which lipos to buy voltage, Capacity and C Rating. The Buggy is kit standard gearing 15 on a 45 Spur with a 2100KV Losi motor and speedo.

Thanks alot in advance
