If you are looking for a cheap pack & don't want to go the a123 rought then you may just want to look at the truerc.net 10c 2s 8kmah pack. They run for like $80 w/ plugs & everything.
Here is a pic of the pack that goes at a buy price for about $60:



Specifications:

4-cell Lithium Polymer 8000mAh Rechargeable Battery Pack
Pack Configuration: 2S1P
Capacity: 8000mAh
Voltage: 7.4V nominal
Wire Gauge: 12
Number of Cells: 4
Maximum Continuous Discharge Rate: 10C
Maximum Burst Discharge Rate: 20C
Connector: 3-pin balancer tab
Dimensions: 45mm x 28mm x 145mm
Weight: 380 grams ( 13.5Oz)
Maximum Continuous Current: 80 Amps

The dimensions are almost identical, with the last length dimension being 5mm longer than the TrueRC pack. If the max burst rating is anything accurate, these are rated better than the TrueRC pack at the burst level (15C versus 20C). I think there listing cell configuration is wrong however. should be 2S2P I am thinking.

I am thinking of trying these if my current source doesn't get in any packs that would fit the size I need.


MikeL: For the RC Pro Series event you attend, what motors were you using with the sidewinders?
