YES - in fact, any type of deep cycle battery can be charged with solar panels. Make sure to use a solar charge controller for deep cycle solar batteries to regulate the charge or add an Ardent Battery Box with Anderson Plug Connections.
**An Anderson style plug is a moulded, heavy-duty connector designed for high current 12V circuits. They are commonly used to create a safe and secure power connection between a battery and the solar panels. Indeed, most caravans and campers these days have Anderson style plugs installed from the factory.
For Lithium Deep Cycle Batteries, you need to make sure the open voltage of the solar panel is below 18V for a 12V battery. It is best if your solar panel has a voltage regulator to stop charging at 14.4V or (LiFePO4) setting of 14.6V.
