12V Lithium Battery Built-in Smart 100A BMS review

?Are we ready to upgrade our power setup with a modern 12V LiFePO4 battery that promises smart monitoring, long life, and lighter weight?

Review Summary: 12V 100Ah LiFePO4 Battery with Bluetooth, 12V Lithium Battery Built in Smart 100A BMS Support Monitoring, 12V 100Ah LiFePO4 for Camping, Trolling Motor, RV, Solar, Off-Grid

We’ll open with a concise summary so we can always come back to the main points. This battery targets users who want a Group 24 form factor but need the performance gains of LiFePO4 chemistry plus smart monitoring via Bluetooth.

We like that it replaces lead-acid in many applications while bringing built-in protections, a compact weight (22.05 lb), and a 5-year warranty. It’s not suitable as a starter or golf cart battery, but for deep-cycle, off-grid, and marine use it’s a strong candidate.

Who this product is for

We think this battery is for RV owners, campers, boaters with trolling motors, and small off-grid solar systems. It’s especially useful where weight matters and where users want to track battery state in real time using Bluetooth.

We would recommend it to anyone switching from Group 24 lead-acid batteries who wants roughly double the usable runtime and far more cycles.

Key Features and Why They Matter

We’ll highlight the standout features and explain why they matter in real usage.

• Smart BMS with Bluetooth 5.0: The built-in BMS connects to the CYCLENBATT app for real-time monitoring. This gives us live voltage, state of charge, and protection alerts.
• Group 24 form factor and lightweight: At 22.05 lb and BCI Group 24 size, it’s a near-direct swap for many RV and marine applications that previously used lead-acid.
• 100Ah capacity at 12V: This offers 1.2 kWh of stored energy and is suitable for many 12V loads and small trolling motors.
• 100A Smart BMS: The battery includes a BMS that manages charge/discharge, and provides multiple protections like overcharge, over-discharge, short-circuit, and temperature cutoffs.
• Cold-weather protections: Charging is cut off below 32°F (0°C) and discharging is cut off below -4°F (-20°C), preserving cell health in low temperatures.
• Long cycle life: Manufacturer-rated at over 5,000 cycles, indicating many years of daily use under proper conditions.
• Expandability claim: The manufacturer states the battery can be configured to form larger systems up to 20.48 kWh under certain configurations.

We appreciate that these features address the common pain points of lead-acid users: weight, cycle life, and lack of monitoring.
