Does it work with my existing charger?

Only if the charger has a lithium or LiFePO4 profile. A lead-acid-only charger will not fill it properly and can shorten its life.

What does the Bluetooth feature do?

It lets you read state of charge, voltage and cell data from a phone app. It does not change how the battery performs.

Will it fit my Group 27 battery box?

Yes. It is built to Group 27 dimensions and fits standard Group 27 boxes and trays without extra wiring.

Can I charge it in freezing weather?

The BMS blocks charging below freezing to protect the cells. Discharging still works, and charging resumes once the battery warms up.

How does it compare with a lead-acid Group 27?

It is much lighter, lasts far more cycles and gives usable capacity down to near-empty. It costs more up front and needs a lithium charger.

The battery itself. Mounting hardware and a charger are not included, so plan for a lithium-compatible charger.

Our take on the LiTime 12V 100Ah Group 27 Bluetooth LiFePO4 Battery

The LiTime 12V 100Ah Group 27 is a lithium iron phosphate deep-cycle battery with a built-in Bluetooth 5.0 monitor and a low-temperature cut-off BMS. It uses EV-grade cells rated for 4000–15000 cycles and drops into a standard Group 27 battery box without rewiring. It suits RV, solar, off-grid and backup-power users who want to watch charge state from a phone. Against lead-acid Group 27 batteries it is far lighter and lasts many more cycles, though it costs more up front and needs a lithium-compatible charger.
