I started with 2 LiPo's and 1 ice at the track (and one ice at home). I added a third LiPo to do some fitup and testing (and to compare the Orion 3600 vs Trackpower 4900). Its nice having the 3 if trying to get alot of practice in a short period of time...but 2 is really all that is necessary IMO.
BTW...Trackpower 4900 25c has more pull then Orion 3600 race spec IMO.
how long a 3250mah li-po last for mod racing? is it easy to make runtime? and if u had to recharge how long would it take?
For TC i would not mess with a 3250. You'll just end up just having to add more weight because they are considerably lighter. May as well make that weight count with added Mah of a 4900 / 5000.
