Core Product Advantages
1. Lightweight Compact Portable Design for Multiple Scenarios
Traditional lead-acid energy storage batteries are bulky and heavy, requiring 2–3 people to move. Syncorepower LiFePO4 battery adopts miniaturized integrated packaging, with the smallest 5.12kWh unit only 44.4kg, easy to carry for RV trips, camping and temporary construction power supply. The uniform stackable size allows flexible capacity expansion from 5kWh up to 64kWh by stacking 4 units, matching different villa and commercial load demands without extra cabinet renovation costs.
2. Ultra-Long Cycle Life Cuts Long-Term Replacement Expense
Ordinary lead-acid batteries only provide 800–1200 cycles and need replacement every 3–4 years, generating high recurring costs. Our LiFePO4 cells achieve stable 3000+ deep cycles, extending service lifespan to over 10 years. Calculated on a 10-year usage cycle, it reduces total battery replacement expenditure by 60% compared with lead-acid alternatives, bringing faster ROI for residential solar storage projects.
3. Built-In Intelligent BMS Ensures Balanced Cell Aging & Stable Output
The embedded intelligent BMS monitors voltage, current and temperature of each cell in real time, automatically activating passive cell balancing during charging to eliminate cell voltage imbalance. It slows down cell attenuation by 50%, maintains consistent full-power output throughout the whole cycle life, and avoids capacity attenuation caused by inconsistent internal cells. No manual calibration is required, realizing zero daily maintenance.
4. Comprehensive Multi-Layer Safety Protection Eliminates Household Fire Risks
Lithium iron phosphate cathode material features excellent thermal stability and will not burn or explode under overcharge, extrusion, nail penetration or short-circuit conditions. The built-in 7-in-1 protection system covers overcharge, over-discharge, over-current, short-circuit, high-temperature, low-temperature and cell imbalance protection, intercepting 99% of abnormal circuit risks and meeting strict global household electrical safety standards.
5. Large Clear Display Screen for Real-Time Energy Visualization
The extra-wide front display panel intuitively shows real-time battery voltage, remaining capacity percentage, charging power and discharging load power. Home users can clearly check solar energy storage and household power consumption status at a glance, reasonably arrange power usage to maximize self-consumption of free solar power and cut monthly utility bills by up to 70%.
6. High Continuous Charge & Discharge Current Supports Heavy Household Loads
The high-current version supports up to 200A rated charge/discharge current, perfectly matching high-power equipment such as central air conditioning, swimming pool heat pumps, electric vehicle chargers and kitchen induction cookers. It maintains stable pure sine wave power output without voltage drop or protection shutdown during peak power consumption hours.

Important Safety & Operation Precautions
Storage Instruction: For long-term idle storage, maintain battery SOC at 50%–60%, and recharge every 3 months to extend overall cycle life.
Stacking Regulation: Only battery packs of the same model, capacity and batch can be stacked in parallel (max 4 units). Professional electrician wiring and parameter matching are required to avoid current imbalance.
Temperature Limit: Do not charge the battery below 0℃ or discharge under -20℃ to prevent permanent cell capacity attenuation. Avoid installing in fully sealed, unventilated high-temperature cabinets.
PV & Inverter Matching: Only use hybrid inverters with 40–60Vdc battery voltage compatibility; mismatched voltage equipment will trigger protection shutdown and damage the BMS.
Safety Installation Rules: Keep the battery away from open flame, flammable materials and direct sunlight. Regularly check the display panel for abnormal voltage or temperature alarms every month.
Load Usage Notice: Do not continuously run loads exceeding the rated discharge current for long periods; sustained overload will activate protection cut-off and accelerate cell aging.
Maintenance Guide: Cut off all connection terminals before inspection or movement. Do not disassemble the sealed battery casing privately, otherwise the official warranty will be voided.
