SD Energy 24V 300Ah Plus is an ultra-high energy-density smart lithium energy storage solution developed for large luxury motorhomes, integrated camper vans, motor yachts, catamarans and professional 24V off-grid energy systems. Equipped with Grade A LiFePO4 cells from a leader in the global lithium market, a JK BMS board specialized in lithium battery current balancing, and a superior 5-year warranty, this model enables real-time, millivolt-precision monitoring of your complete energy status from your phone via its integrated Bluetooth connection.
Compared with 12V systems, a 24V system architecture halves the current flowing through your electrical installation, preventing cable heat build-up, maximizing electrical efficiency and allowing smaller cable sizes to reduce installation costs. SD Energy 24V 300Ah delivers a massive net energy reserve of 7680Wh (7.68 kWh) in one compact enclosure. The Plus model offers enhanced reliability in systems operating continuously under high charge and discharge loads. Thanks to next-generation cell technology, it delivers this substantial power at a weight of only 30.5 kg, providing remarkable weight savings for your camper van or boat. The active-balancing architecture of its intelligent JK BMS board continuously equalizes cell voltages, maintaining the battery in first-day condition for 6,000 cycles at 80% DoD.
Ultra-Lightweight, High Energy Density: Next-generation cell architecture that delivers a massive 7.68 kWh energy capacity in a body weighing only 30.5 kg.
High-Efficiency 24V System Architecture: An operating platform fully compatible with high-power inverters, marine systems and DC-DC devices, minimizing electrical losses and installation heat build-up.
Genuine LiFePO4 Cells: EVE quality from one of the world’s most trusted lithium manufacturers, delivering high-current stability, superior safety and maximum cycle life.
Smart JK BMS System: Active cell balancing helps prevent overheating and unbalanced charging, while providing comprehensive protection against overcharging, over-discharging, high-current and short-circuit risks.
Precision Bluetooth Integration: Wirelessly monitor each lithium cell’s voltage, real-time charge/discharge current and temperature through the mobile app, without opening the battery enclosure.
High-Current and Power Output: With 300A continuous discharge current and 450A peak-current support for up to 10 seconds during start-up surges, it powers 24V rooftop air conditioners, bow thruster systems and heavy industrial loads with ease.
5-Year Assurance: A one-to-one replacement with a new product warranty for manufacturing defects during the first two years, followed by a free technical repair warranty for the next three years.
