Frequently Asked Questions

What is a LiFePO₄ lithium battery?

LiFePO₄ (Lithium Iron Phosphate) is a lithium battery chemistry designed for long cycle life, stable performance and deep cycle applications. It is commonly used in RV, marine, solar and backup power systems.

How much energy does a 314Ah lithium battery provide?

At a nominal voltage of 12.8V and capacity of 314Ah, this battery provides approximately 4019Wh (4.02kWh) of energy storage. This makes it well suited to systems requiring substantially more runtime than a typical 100Ah battery.

How does this battery compare to a 100Ah lithium battery?

The VTL12-300 provides approximately three times the energy storage of a 100Ah LiFePO₄ battery. This can reduce the number of individual batteries required in high-capacity RV, marine, solar and backup power installations.

How does lithium compare to lead-acid batteries?

LiFePO₄ batteries typically provide longer cycle life, faster charging, lower weight for a comparable amount of usable energy and more consistent voltage under load than conventional flooded or AGM lead-acid batteries.

Do I need a special charger?

A charger with a charging profile suitable for LiFePO₄ batteries is recommended. If using a multi-chemistry charger, select the lithium or LiFePO₄ setting specified by the charger manufacturer.
