The RopeCT is a flexible, highly accurate current transformer for measuring current flow in larger battery systems with larger buss work. It comes in two lengths, 24 in. (60 cm) and 36 in. (90 cm) for 8 in. (20cm) and 12 in. (30 cm) diameters, respectively. Since it is flexible, it could form into an oval to easily fit around most any buss work or intercell connection configuration. The RopeCT is designed specifically for use with the BITE 2, BITE 2P, and the BITE 3.
