The KickAss Smart 12V 120Ah Lithium Deep Cycle Battery gives you roughly twice the usable capacity of a 120Ah AGM in a fraction of the weight, lithium can safely be drawn down to 80%, where AGM is limited to about 50%. In practical terms it does the work of a 240Ah AGM.

120Ah LiFePO4 with Bluetooth Monitoring

Rated for 4000+ cycles at 80% depth of discharge with an integrated BMS protecting against short circuits, overload, overcharge and low voltage. Bluetooth monitoring through the app shows state of charge, voltage, current and time to empty, and an optional remote display unit does the same on a fixed screen. Up to four can be linked in series or parallel, charge each one fully before connecting them.
