SW-SI-12V100AH is a 12 V / 100 Ah sodium-ion battery delivering 1.2 kWh of energy with over 3,000 cycles at 100% DOD — a long-life, cold-resistant power source for solar storage, backup power, and other 12 V applications.

Nominal Voltage	12 V
Nominal Capacity	100 Ah
Rated Energy	1.2 kWh
Cycle Life	≥ 3,000 cycles (100% DOD, 0.5C/0.5C)

The SW-SI-12V100AH is a 12 V / 100 Ah sodium-ion battery engineered as a high-performance, long-life power source for 12 V energy storage applications. With a nominal capacity of 100 Ah and rated energy of 1.2 kWh, it delivers stable power across a wide temperature range — charge from -10°C to 55°C and discharge from -30°C to 55°C — making it especially suitable for cold environments where conventional batteries struggle

Built with 3 V / 10 Ah sodium-ion cells in a 4S10P configuration and housed in a durable ABS enclosure rated IP65, the battery supports up to 100 A continuous charge and discharge current (50 A recommended), with a charge limit of 16 V and discharge cut-off between 8 and 9 V. It offers a cycle life of over 3,000 cycles at 100% DOD (0.5C/0.5C, until capacity decays to 70%), ensuring dependable long-term performance. Certified to UN38.3 with MSDS documentation, the SW-SI-12V100AH is a safe, lightweight (12.5 kg), and low-maintenance choice for solar storage, backup power, and other 12 V systems.
