SD Energy 24V 300Ah 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. 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 EVE LiFePO4 Cells: 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 200A continuous discharge current and 350A 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 2K Karava 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.
