Description
The Ionnic BMS-ES and BMS-IMP are 60mm solid brass extension studs that screw onto a battery master switch terminal to give heavy cables and lugs more clearance. They help when large cable lugs, terminal insulators or a jump-start connector crowd the switch terminals.
The BMS-ES has an M10 thread and suits the BMS-001, BMS-002, BMS-20 and all Ionnic L handle switches. The BMS-IMP has a 3/8″-24 thread and suits the BMS-17 and the Cole Hersee 75920, 75903, 75910B and 75912B.
Solid brass gives good conductivity and corrosion resistance. Select the thread above to match your switch.
