This is a pack of TQ Racing 13 gauge wire in red, 3' in length. 

TQ13 is constructed with 1,296 strands of bare copper and thin wall silicone. This wire is only 3.5 mm OD… as thin as most 14 gauge wire, and delivers more power! The compact 13 gauge conductor fits easily into ESC’s and BL solder terminals. Thin and super flexible to make quick work out of neatly wiring any car.
