BSLB 7Kw 51.2V Battery

The BSL Battery 51.2V – 135Ah CANBUS (7kWh) is a robust and reliable lithium-ion energy storage solution designed for residential, commercial, and off-grid solar systems. Built with modern lithium iron phosphate (LiFePO4) chemistry, this battery offers a compelling combination of safety, performance, and longevity, making it an excellent choice for anyone wanting dependable backup power and efficient renewable energy storage.

With a nominal voltage of 51.2 V and a capacity of 135 Ah, the BSLB 7 kWh battery stores approximately 7 kilowatt-hours of usable energy. This capacity is large enough to support typical household loads during power outages or supplement solar generation to maximize self-consumption and reduce grid reliance. Whether paired with hybrid inverters in solar installations or used in standalone battery backup systems, the BSLB battery provides substantial power where it’s needed.

One of the standout features of this model is the CANBUS communication interface. This advanced communication protocol allows for precise monitoring and control of the battery’s status, health, and performance. Through a compatible inverter or battery management display, users can track key metrics such as state of charge, voltage, and temperature, enabling smarter energy decisions and improved system reliability.

The LiFePO4 chemistry used in this battery is widely regarded as one of the safest lithium technologies available. It provides superior thermal stability, high resistance to abuse, and a significantly lower risk of thermal runaway compared with other lithium-ion types. The battery also has a low self-discharge rate (typically under 3 %), which helps maintain stored energy for longer periods when not in active use.

In terms of durability, the BSLB 7 kWh battery delivers thousands of charge/discharge cycles—often spanning a service life of more than a decade with minimal performance loss. This longevity translates to a lower cost of ownership over time compared with traditional lead-acid batteries, which degrade faster and require more frequent replacements.

Practical installation is another advantage. The battery’s modular, maintenance-free design and relatively compact footprint make it suitable for floor-standing, racking, or battery cabinet systems. It also typically features built-in protection mechanisms against over-voltage, under-voltage, over-current, and temperature extremes, adding layers of safety and peace of mind.

Overall, the BSLB 7 kWh 51.2 V – 135 Ah CANBUS Lithium Battery is a strong contender in the mid-range lithium storage category. It combines high capacity, advanced communications, excellent safety, and long service life to deliver reliable, efficient energy storage for a wide variety of applications, from solar support to emergency backup power.
