Protect, monitor and look after the battery that runs your 12V system.
Battery Management — Looking After Your Battery
Choosing and sizing a battery is only the start. Once it's installed, battery management is what keeps it protected, tells you how much power you have left, and helps it last.
Lithium batteries rely on a battery management system (BMS) to protect the cells. A battery monitor and shunt show the charge going in and out, an isolator lets you switch the system off safely, and some batteries add low-temperature protection for cold trips.
Explore the guides, tools and equipment below to understand how to protect and monitor your battery and get the most from your system.
