When cycled daily, this translates into over 16 years of reliable, maintenance‑free service – outlasting lead‑acid equivalents by an order of magnitude. Considering the total lifetime energy throughput (8.04 kWh × 6,000 cycles = over 48,000 kWh), this 25.6V 314Ah battery represents an exceptionally low total cost of ownership for commercial fleets, remote telecom installations, and serious off‑gridders who demand maximum return on their energy storage investment.

Intelligent Dual‑Layer BMS with Bluetooth Telemetry for Commercial Oversight

Managing a high‑capacity battery bank requires sophisticated monitoring, which is why this pack integrates a state‑of‑the‑art Battery Management System alongside robust Bluetooth communication. The dedicated mobile application provides instant, real‑time visibility into per‑cell voltage balancing, internal temperature gradients, precise state of charge and health metrics, and comprehensive historical cycle logging. This level of transparency is invaluable for system integrators and fleet operators, as it enables predictive maintenance, remote diagnostics, and automated alerting before any performance degradation occurs, ensuring that your critical 24V solar array or UPS system remains operational around the clock with minimal hands‑on intervention.

Industrial‑Grade Enclosure Designed for Permanent, Secure Installation

With its generous 640 mm length, 245 mm width, and 210 mm height, this 314Ah battery is engineered to be securely mounted in standard 19‑inch equipment racks, dedicated battery cabinets, or floor‑standing enclosures. The flame‑retardant PC+ABS shell is reinforced to withstand significant vibration and mechanical shock, making it equally suitable for stationary home storage and mobile applications such as large yachts and electric shuttle buses. Weighing 49.5 kilograms, it delivers exceptional energy density per kilogram, and its wide operational temperature range of -10 °C to 60 °C ensures consistent performance across diverse climates, while the optional integrated self‑heating module enables safe charging in sub‑zero environments down to -20 °C for polar or high‑altitude deployments.

Seamless Scalability for 48V Banks and Parallel High‑Capacity Arrays

While a single 8.04 kWh unit is already immensely powerful, the 25.6V 314Ah battery is designed to be the perfect building block for even larger energy systems. You can connect two units in series to create a robust 48V 314Ah bank (16.08 kWh) for standard residential hybrid inverters, or wire multiple units in parallel to multiply the total amp‑hour capacity – for instance, four parallel units deliver a staggering 1,256 Ah at 24V, providing over 32 kWh of backup power for entire commercial premises. The intelligent BMS handles interconnection gracefully with automatic balancing, and our technical engineering team supplies detailed wiring diagrams and pre‑charge circuit recommendations to guarantee a safe and flawless integration.

Comprehensive OEM Customisation and Global Regulatory Compliance for Brands

For distributors, system integrators, and private‑label brands, this large‑format battery offers extensive customisation opportunities starting from very modest minimum order quantities. We can tailor the external labelling, packaging design, user documentation, communication protocol (CAN bus, RS485, or Modbus), and even the terminal lug orientation to perfectly match your existing product ecosystem. Furthermore, every unit leaves our factory fully certified with UN38.3, MSDS, UL1642, CE, FCC, IEC62619, and RoHS, ensuring that your shipments clear customs effortlessly and your end customers receive a product that meets the highest international safety and performance standards, reinforcing your brand's reputation for quality.

Frequently Asked Questions (FAQ)

This is a 24V LiFePO₄ battery with a nominal voltage of 25.6V (four cells in series). Its actual operating voltage spans from approximately 20V to 29.2V, which is perfectly aligned with the input window of all standard 24V inverters, solar charge controllers, and DC‑DC converters designed for lead‑acid or lithium profiles. It is a direct voltage replacement but with far superior energy density and cycle life.

The rated energy is 8.04 kWh, calculated precisely as 25.6V × 314Ah = 8,038.4 Wh. We round this to 8.04 kWh for clarity. This large figure is what makes this battery suitable for whole‑home backup, as it can power a typical 500W base load for over 16 hours continuously.

Runtime depends on your combined load. For a constant 500W draw (lights, modem, refrigerator, TV), you can expect approximately 16 hours of runtime. For a higher 2,000W load (microwave, power tools, water pump), it will deliver about 4 hours. To calculate precisely, use the formula: 8,040 Wh / Load (W) × Inverter Efficiency (usually 0.90 for good quality units).

While the 100Ah version offers 2.56 kWh for portable or compact setups, the 314Ah version provides more than triple the energy (8.04 kWh) in a larger, heavier package designed for fixed installations. You would choose the 314Ah if you have higher daily energy consumption, intend to run heavy loads for extended periods, or plan to achieve full energy autonomy for a household, a telecom site, or an electric vehicle fleet without connecting multiple smaller batteries in parallel.

Absolutely. Two units can be connected in series to form a 48V 314Ah bank (16.08 kWh), which is standard for many high‑power residential hybrid inverters. Multiple strings in series‑parallel are also possible for 96V systems, though we strongly recommend consulting our technical team to design the optimal busbar and balancing architecture for your specific application to ensure longevity and safety.

The standard version supports charging only above 0°C to prevent lithium plating. For cold climates, we offer an optional built‑in heating film system that draws a small current from the charging source or the battery itself to warm the cells to a safe temperature before the main charge current is applied. This enables reliable operation down to -20°C, making it suitable for unheated garages, mountain cabins, and polar expeditions.

The TURSAN app displays per‑cell voltages, per‑cell temperatures, total pack voltage, charge/discharge current, State of Charge (SOC), State of Health (SOH), total cycle count, and any active protection alarms (over‑voltage, under‑voltage, over‑current, short‑circuit). Bluetooth range typically extends to 10 metres in open space, allowing you to check system status comfortably from a control room or vehicle cabin.

Yes. We offer full OEM flexibility. Standard terminals are M8 studs, but we can adapt to M10, quick‑connect Anderson plugs, or busbar‑specific interfaces upon request. Communication can be factory‑configured to CAN 2.0B, RS485, or Modbus RTU, ensuring seamless integration with your preferred BMS master or SCADA monitoring system.
