SD Energy 24V 200Ah is a high-efficiency smart lithium energy storage solution specifically developed for modern camper vans, luxury boats, motor yachts and next-generation 24V off-grid solar 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 offers the convenience of monitoring your complete energy status in real time and with millivolt precision from your phone through its integrated Bluetooth connection.
Compared with 12V systems, a 24V system architecture halves the current flowing through your electrical installation. Lower current helps prevent heat build-up, maximizes energy efficiency and allows the use of smaller cable sizes in your camper van or boat—reducing installation cost and weight. SD Energy 24V 200Ah delivers a substantial net energy reserve of 5120Wh (5.12 kWh) in a single compact enclosure. Its dedicated JK BMS board uses active balancing to continuously equalize cell voltages, maintaining the battery in first-day condition for 6,000 cycles at 80% DoD.
High-Efficiency 24V System Architecture: An operating platform fully compatible with high-power inverters and DC-DC systems, minimizing electrical losses and cable heating.
Genuine 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 Karavan Market 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.
