CURRENT-BT battery custom with a 30A current capacity, including connection cables. - Model Name: CURRENT-BT - Function: Battery Custom - Current Capacity: 30A - Retail Price: ¥30,800 (tax included) Following the discontinued REVAMP-Current, development of a product specifically for the main battery was started, and after several months of testing, the new "CURRENT-BT" was born. A dedicated case made of ultra-heat-resistant resin (HIGH HEAT ABS) is used. Also, by incorporating a built-in fuse, an external fuse is unnecessary. The regenerative capability is 1.2 times that of REVAMP-Current, and cost reduction is achieved by adopting a new IC and mass procurement. The main battery is designed to improve the resolution of the mid-low range and the sound separation of the mid-woofers, and the internal structure is a two-layer structure for heat resistance, minimizing impedance rise at high temperatures.
