3. Product Features
The Renogy 12V 100Ah Smart Lithium Iron Phosphate Battery PRO LT Series offers advanced features for reliable power storage:
- Dual Active Protection System: Features over 60 BMS protections and an active backup protection system. This system cuts the circuit in case of hardware failure, protecting the battery from continuous overheating. It responds 40 times faster than conventional systems, within 15 seconds.
- Integrated Self-Heating Function: Allows charging in cold environments (below 5°C). Heating starts automatically below 5°C and stops above 10°C. Requires a stable charging current of at least 4A per battery from the charging device for the heating function to operate.
- Bluetooth Monitoring: Built-in Bluetooth enables easy monitoring of battery parameters via the DC HOME app.
- UL94 V-0 Fire-Retardant Casing: Enhanced casing with a UL94 V-0 fire rating actively prevents the spread of vertical burning within 10 seconds, maximizing protection for the battery and your system.
- Wobble-Free Design: Features a robust internal structure to support cells and protect against vibration. Integrated mounting holes and a battery fix bracket ensure secure installation in RVs or other applications.
- Superior Durability & Protection: Offers a long cycle life of over 5000 cycles at 80% Depth of Discharge (DOD). It boasts an IP67 waterproof rating and ISO 9227 certified corrosion resistance, ensuring reliable performance in harsh environments.
