WATTSTUNDE® NOVA Base 2 200Ah LiFePO4 Battery
WATTSTUNDE® NOVA Base² 200 Ah LiFePO4 Battery – High Capacity for Your Energy System
The NOVA Base² 200 Ah is the consistent further development of the proven NOVA Base series, offering you the most powerful energy storage solution within this series with a capacity of 200 Ah and a nominal voltage of 12.8 V. The second generation has been specifically optimized – including a more powerful battery management system with higher discharge current and lower self-consumption. In addition, the battery complies with current standards such as ECE R10.7, making it technically state-of-the-art.
Optimized Battery Management System
The integrated Battery Management System (BMS) has been revised and allows for short-term discharge currents of up to 300 A (< 30 min). At the same time, it reliably protects the battery from overcharging, deep discharge, overheating, and short circuits.
Efficient in Operation: Low Self-Consumption
With a reduced self-consumption of only approx. 2.5 mA/h, your battery remains ready for use longer even during idle times and operates more efficiently than the previous model.
New Design & Current Standards
The battery comes with a revised design and new packaging. In addition, it meets requirements such as ECE R10.7 and the EU regulation EU2023/1542, thus complying with current technical standards.
