Can I use this to replace a 12V lead-acid battery?

Yes, 12.8V 100Ah LiFePO4 is the usual drop-in size for a 12V deep-cycle battery. Check that your charger has a lithium profile and that your gear tolerates the slightly higher charging voltage.

Does it have a built-in battery management system?

The listing does not state one. A BMS protects against overcharge, over-discharge and short circuits, so confirm with the seller that this battery includes one before buying.

What charger do I need?

Use a charger with a LiFePO4 or lithium setting. A standard lead-acid charger can overcharge it or fail to top it off properly.

How many batteries can I connect together?

Series and parallel limits depend on the BMS, which is not listed here. Ask the seller for the maximum series and parallel configuration before building a bank.

Can it be charged below freezing?

Charging LiFePO4 below 0°C damages the cells unless the battery has low-temperature cutoff. The listing does not mention this protection, so avoid cold charging unless the seller confirms it.

The listing describes a single battery sold individually. It does not mention terminals, cables or a charger, so plan to supply those separately.
