What is the best battery for a dual battery system?
Battery Options There are three main options when it comes to the battery you select for your dual battery system. These options are lead acid deep cycle (Good), AGM (Better) or Lithium (Best). Lead acid deep cycle batteries are suitable for under bonnet or in an open tray or tub.
What are the benefits of a dual battery system?
Here are some of the benefits of having a dual battery system:
- Ensures minimal loss. As a result, the dual battery system becomes a key tool to ensure minimal loss and where possible prevention of total loss.
- It increases durability.
- It saves time.
- It boosts dependability.
- It increases mobility.
- It reduces fire risk.
Do I need a second battery for inverter?

How long will a 12V battery last with a 1500 watt inverter?
13 minutes
How long will a 12v battery last with a 1500 watt inverter? A 12 volt 50Ah lithium iron phosphate (LiFP04) battery with regular depth of discharge (DoD) of 80% will run a fully-loaded 1500 watt inverter for 13 minutes. The calculation incorporates typical pure sine wave inverter efficiency of 95%.
Do I need a bigger alternator for dual batteries?
You can run two batteries on the same alternator. The alternator registers these two batteries as a single large battery and charges them the same. The batteries self-regulate the amount of current they take as they charge. This means that a single alternator is effective for multiple batteries.
