12V 100Ah LiFePO4 Battery

Q: Can a 12V LiFePO4 battery directly replace my lead-acid battery?

In most 12V systems, yes. The 12V 100Ah LiFePO4 battery is built as a drop-in replacement with a similar footprint and terminal layout, so it fits standard battery boxes. You should confirm that your charger or solar controller supports a lithium charging profile.

Q: What charger do I need for a 12V LiFePO4 battery?

Use a charger or MPPT solar controller with a LiFePO4 / lithium profile (14.2V–14.6V absorption, no equalisation mode). Many modern chargers have a selectable lithium mode; older lead-acid-only chargers with a desulphation pulse should be replaced.

Q: How many 12V 100Ah batteries do I need for home backup?

Each 12V 100Ah battery stores about 1.28kWh. For a 5kWh usable backup bank you need roughly four units in parallel, or you can move to a single 48V pack, which is the usual choice for whole-home systems.
