Description
Advanced Safety with Integrated Intelligence
Safety is the cornerstone of any industrial-grade energy solution. Our 12V LiFePO4 deep cycle battery is equipped with a sophisticated Smart Battery Management System (BMS) that provides comprehensive protection against over-charging, deep discharge, and thermal runaway. This intelligent core not only extends the battery’s lifespan to over 5,000 cycles but also ensures stable performance for critical systems, giving wholesalers and project managers peace of mind.
Engineered for Scalability and Efficiency
Understanding that every energy project has unique requirements, SolarDyna has optimized these units for maximum flexibility. The series supports 4S4P expansion configurations, allowing you to scale up to a 48V system or increase total capacity effortlessly. Complementing this scalability is a 99.9% charging efficiency and an ultra-low self-discharge rate of less than 3% per month, ensuring that your solar storage battery remains ready for action whenever it’s needed.
User-Centric Design for Modern Applications
Beyond the internal technology, the user experience is enhanced by a rugged, lightweight ABS casing that is significantly easier to transport and install than bulky AGM alternatives. Each unit features a clear Digital LED Display for real-time voltage monitoring, alongside versatile USB and DC output ports. These features make our batteries a favorite for the RV and Marine sectors, where space-saving designs and intuitive interfaces are highly valued.

Frequently Asked Questions | 12V LiFePO4 Battery Series
Q1: What is the maximum scalability of this 12V battery series?
A: Our batteries are designed for flexible system expansion. You can connect up to 4 units in series to create a 48V system and up to 4 strings in parallel to increase total capacity (4S4P configuration). This makes it an ideal solution for scaling energy storage in residential or light commercial projects.
Q2: Does the battery come with a built-in BMS, and what does it protect against?
A: Yes, every SolarDyna LiFePO4 battery features an integrated Smart Battery Management System (BMS). It provides real-time protection against over-charging, over-discharging, over-current, short circuits, and extreme temperature fluctuations, ensuring a lifespan of over 5,000 cycles.
Q3: Can these batteries directly replace my existing Lead-Acid or AGM batteries?
A: Absolutely. These are designed as “drop-in replacements.” They share similar form factors with Group 24, 27, and 31 lead-acid batteries but offer 1/3 the weight and significantly higher usable energy (100% Depth of Discharge vs. 50% for lead-acid). No major wiring overhaul is required for most 12V systems.
Q4: What is the typical lead time for bulk wholesale orders?
A: For standard specifications, our lead time is generally 15–25 days depending on order volume. We also maintain a rotating safety stock for our most popular models (100Ah and 200Ah) to support urgent project requirements. Please contact our sales team for a precise delivery schedule to your region.
Q5: Do you offer OEM/ODM services for branding and technical customization?
A: We do. We support B2B clients with private labeling (OEM) and custom casing designs. Additionally, we can adjust technical parameters such as specific discharge rates or add communication ports (like RS485/CAN) for large-scale ODM projects to ensure compatibility with specific inverter brands.
Q6: How does the battery perform in extreme temperature environments?
A: Our LiFePO4 cells are rated for discharge between -20°C and 60°C (-4°F to 140°F). For charging, we recommend staying within 0°C to 45°C. If your project is located in a sub-zero climate, we can provide optional self-heating film technology to maintain charging efficiency in winter.
Q7: What kind of warranty and technical support do you provide to international distributors?
A: We offer a standard 5-year warranty on our 12V LiFePO4 series. For our global partners, we provide comprehensive technical data sheets, installation manuals, and direct access to our engineering team for troubleshooting or system design consultation.
Q8: Are the batteries certified for international shipping and safety?
A: Yes, all SolarDyna lithium products comply with international safety standards and hold certifications including UN38.3, CE, and MSDS. We ensure all bulk shipments are packaged according to Class 9 Dangerous Goods regulations to guarantee safe and compliant transit via sea or air.
