The Victron Energy Cyrix-Li-Charge 12/24V-120A intelligent charge relay connects a battery charger to a LiFePO4 battery when permitted by the VE.Bus BMS. Designed for 12V and 24V systems, it provides controlled charger connection with 120A continuous current and helps protect the battery during charging.
The relay disconnects immediately when the BMS signals cell overvoltage or overtemperature, then reconnects after a three-second delay when conditions recover. With IP54 protection, low open-state consumption and automatic charger checks during operation, it supports reliable BMS-controlled lithium charging systems.
