About this item

• High Energy Density & Lightweight Design: Packing 25.6V 100Ah / 2560Wh of power in a compact, lightweight body (70% lighter than lead-acid), this lithium battery ensures stable voltage output for RVs, solar systems and off-grid setups. Its high energy density maximizes runtime for appliances, lights, and critical devices.
•  
• 10x Longer Lifespan vs. Lead Acid: Dumfume 24V 100Ah LiFePO4 Lithium Battery, built with automotive-grade LiFePO4 cells, delivers 4000+ deep cycles (10x more than lead-acid batteries) and supports 100% Depth of Discharge (DOD). Say goodbye to frequent replacements—this battery lasts up to 10 years with stable performance, even under daily heavy use.
•  
• Fast Charging & Scalable Power: Pair with Dumfume 29.2V 20A lithium battery charger for a full recharge in just 5 hours (vs. 10+ hours for lead-acid). Compatible with solar controllers,inverters,and mainstream lithium charging equipment.It supports 4P2S configurations to create a 48V 400Ah system (20.48kWh), perfect for expanding home backup or commercial energy storage.
•  
• Smart BMS for Ultimate Safety: Equipped with 100A BMS, the battery safeguards against overcharge, over-discharge, over-current, short circuits, and low/high temp. Dumfume 25.6V 100Ah LiFePO4 Battery maintains consistent voltage stability across extreme temperatures (Charge: 0°C–50°C / Discharge: -20°C–60°C), ensuring reliability in harsh environments.
•  
• Note And Customer Service: Under various temp/humidity measurement methods and instruments, voltage and current May deviate by 1%~5%. Charge/discharge battery once every 6 months to prevent damage from disuse. Attention: The Dumfume LiFePO4 battery is intended for use as an energy storage, please do not use this battery as starting batteries.
