For classes other than the Sportsman Truck class, 1-cell Lipo batteries (nominal voltage; 3.7v) which have received ROAR approval and are available (as defined by ROAR) to the public on or before October 1st, 2012 are to be used. Summer season approval date is May 1 2013.
The only battery permitted for the Sportsman Truck class is the SMC 4000 mAh, 25c pack, PN4025S
I guess that's a shame, but I understand a mfg. having a higher price for lower quantities.
We currently have basher packs available from GensAce, who is not by any means a competition based company, but they offer a 1c pack through HobbyPartz for just $23.00 and change, with FREE SHIPPING on $50.00 orders.
We've also bought stuff from Pat at rclipos.com, who also is able to offer FREE SHIPPING.
In my opinion, this is the other battery market, but this one deals in more of a volume based arena than a performance based one. It would be nice to see a better mix of quality in this lower arena.
I'm sure you've seen ads for GensAce and HobbyPartz.com stuff, and I don't know if SMC could be made available through a lipo battery distributor like www.rclipos.com or not.
