About the 48V 15kWh NEXUS Battery

The word “nexus” is a rarely used one in English, but it is an appropriate name for the NEXUS batteries available at BigBattery. 

It means, roughly, “that that interconnects with something else,” but it carries connotations of being a link in a chain where something is coming, something highly anticipatory. 

That’s fitting, considering what the 48V 15kWh NEXUS battery offers: 

• Power and longevity. The 48V 15kWh NEXUS battery offers powerful performance and is rated to last 6000 cycles if not longer, much longer than lead-acid batteries that are commonly used as home battery backups. 
• NEXUS batteries sport LiFePO4 battery chemistry that is extremely stable and safe, and unlikely to experience thermal runaway, unlike some other lithium batteries. 
• A self-heating design. Lithium batteries are notorious for their sluggish performance in cold weather, but this one is equipped with a self-heating system that raises its operating temperature in the cold. 
• Advanced battery management system protection. Battery management systems do much more than help protect the battery in question against thermal runaway. They also monitor the state of charge as well as the health of each battery’s cells during charging and discharging cycles, ensuring optimal performance and long service life. 
• Modular expansion. NEXUS batteries can relatively easily be scaled up from 15kWh to up to 225kWh as needed by the installation setting, and are suitable for both residential and commercial installs. 
• A compact design. NEXUS batteries can be installed on the ground, freeing wall space and simplifying the design of the home battery backup system.
• Flexible, scalable power solutions. These batteries support off-grid installations and provide scalable solutions for home and business owners. Where one battery will not suffice, others can be installed. 
• A wide range of compatibility. NEXUS batteries are compatible with all BigBattery APEX inverters as well as EG4 inverters, simplifying system design and streamlining installation. 
• Maintenance-free. Lithium batteries like these require no maintenance considerations compared to lead-acid batteries that are commonly used as a cost-effective alternative in home battery backup systems. 
• Buy with peace of mind. NEXUS batteries are covered by a 12-year warranty as well as lifetime, US-based tech support. 

What Else These Lithium Batteries Offer

As lithium batteries, these offer a wide range of advantages over lead-acid batteries that are commonly used in home battery backup systems. For instance, they:

• Are long-lasting. 
• Are safe.
• Are compact and relatively lightweight. 
• Offer high energy density. 
• Require no maintenance. 

And more, these are just some of the high level notes comparing the utility of lithium batteries with lead-acid for home battery backup systems.
