Can it replace a Group 24 lead-acid battery directly?

Yes. It is sized for a standard Group 24 box and uses top posts, so it drops in without extra wiring. You do need a charger with a lithium profile.

Can I use it as a car starting battery?

No. It is a deep-cycle battery for RV, solar and backup power, not for engine cranking.

How long does it last?

LiTime rates it for 4,000 to 15,000 cycles, depending on depth of discharge and how it is charged.

Does it have built-in protection?

Yes. A built-in BMS provides overcharge and short-circuit protection.

About 21 lb, roughly half the weight of a comparable lead-acid Group 24 battery.

Our take on the Litime 12V 100Ah Group 24 LiFePO4

The LiTime 12V 100Ah Group 24 is a lithium iron phosphate deep-cycle battery built to drop into a standard Group 24 box. It weighs about 21 lb, roughly half a comparable lead-acid battery, and its built-in BMS guards against overcharge and short circuits. LiTime rates it for 4,000 to 15,000 cycles, far beyond the few hundred a flooded or AGM battery manages. It suits RV, camper, solar and backup setups where weight and cycle life matter more than the lowest upfront outlay.
