What is a dual battery system?
The idea of a dual battery system is to have all (or most) of your accessories connected to the second battery besides your starter battery. As your accessories use power from the second battery the isolator prevents power from draining from your main starting battery leaving it ready for you to start your vehicle when needed. When you start your vehicle, the isolator senses the charge from your alternator and links the 2 batteries together and charges them as you drive.
Some more details what a dual battery system is and does you can read on the whichcar article.
Why should I buy Lithium instead of AGM?
Lithium has more usable energy in comparison, is lighter and lasts longer which is an advantage for this portable battery box. As well AGM Batteries are sensitive to depth of discharge. This means the deeper the battery is discharged, the fewer cycles it has. AGM Batteries are generally recommended to only be discharged to 50% of their capacity to maximize their cycle life. A Lithium (LiFePO4) Battery, on the other hand, is not affected much by depth of discharge so it boasts a much longer cycle life. Its DOD of 80-90% means a longer life circle and cheaper in the long run. Find here a detailed comparison on the Victron Energy blog.
