SVOLT L500-350Ah: The 20-Year Battery Specialist The SVOLT L500-350Ah is a technological marvel engineered specifically for the stationary energy storage market. Utilizing SVOLT’s proprietary “Flying Stack + Short Blade” manufacturing process, this cell achieves a balance of energy density, safety, and extreme longevity that traditional jelly-roll wound cells cannot match.
🚀 15,000 Cycle Life: Designed to operate for over two decades in daily cycling applications, the L500-350Ah offers a verified cycle life of 9,000 to 15,000 cycles. This significantly reduces the total cost of ownership for commercial and utility projects.
📐 Efficient Thermal Design (26mm): At only 26mm thick, this slim profile allows for superior heat dissipation. By preventing internal heat accumulation, the cell ensures uniform thermal distribution during rapid charging and discharging.
⚡ High Energy Density (>170Wh/kg): Packing 350Ah into a streamlined form factor allows for high-density integration in standard 20ft containers (up to 5MWh+) and industrial cabinets.
✅ Guaranteed Authenticity: We supply 100% genuine Grade A SVOLT cells. Given the specialized nature of “Flying Stack” technology, ensuring authenticity is vital for system safety and performance matching.
🎯 Professional Project Support: Consistency is key for large-scale storage. DLCPO provides a Free Sorting Service to match voltage and impedance, ensuring your battery bank remains balanced over its long lifespan.
🌐 Heavy Freight Expertise: We specialize in the logistics of heavy palletized battery shipments. Our comprehensive DDP (Delivered Duty Paid) service to the USA, Europe, and Brazil makes importing industrial-grade components seamless.
The 350Ah version is specifically designed with a 26mm thickness, whereas the larger 770Ah version is 53mm thick. The 350Ah model allows for more granular system design and offers superior cooling efficiency in certain modular configurations.
This specific model is not recommended for EVs. It is highly optimized for Energy Storage Systems (ESS) with a focus on ultra-long cycle life at lower C-rates (typically 0.5C). For EV applications, we recommend SVOLT’s high-rate blade batteries (like the L600 series).
It is a high-speed stacking process that aligns internal electrode sheets with extreme precision. This architectural improvement increases energy density and safety compared to the older “jelly roll” winding method, which is critical for maintaining performance over a 20-year lifespan.
The SVOLT L500-350Ah is a specialized “Long-Life” Energy Storage cell. Utilizing the advanced “Flying Stack” process and a slim 26mm profile, it delivers an industry-leading cycle life of up to 15,000 cycles, specifically optimized for 20-year grid storage projects.

Stop charging cells if charging isn’t completed within the specified time.
Stop using cells if the battery becomes abnormally hot, develops an odor, becomes discolored, deformed, or develops any other abnormal conditions during use, charge, discharge, or storage.
Keep away from fire or hot heat sources immediately when a leakage or foul odors are detected. If liquid leaks onto your skin or cloths, wash it out with plenty of fresh water immediately if liquid leaks from cells and gets into your eyes, don’t rub your eyes. Wash your eyes out with plenty of clean water and seek medical attention immediately
Notice: This is a specialized Energy Storage cell (0.5P rate). Not for EV racing. Ensure proper compression fixtures (26mm thickness) for maximum cycle life.
