About the 48V 15kWh NEXUS Battery

Bigbattery10 Jun, 2026Business

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.

Key Differences Between Lithium-Ion and LFP Batteries

Bigbattery08 Jun, 2026Business

Obviously the main difference between lithium-ion and LFP batteries is in the battery chemistry. The former uses lithium-ion chemistry as a cathode material and the latter uses lithium-iron-phosphate as a cathode material. The nominal voltage per cell of most LiFePO4 batteries is slightly lower than li-ion cells at 3.2 volts compared to somewhere between 3.6 to 3.7 volts per cell for the latter. This means that li-ion batteries have slightly higher energy density.

Why Over Charge and Deep Discharge Damage Lithium Batteries (and How a Battery Management System Hel

Bigbattery25 May, 2026Business

You’ve heard of the many virtues of home battery backup systems with advanced, modern lithium batteries, like LiFePO4 (or LFP) batteries. They are lighter, have higher energy density, last longer, provide more consistent output, and are easier to maintain, to name just a few.

Home Battery Backups: How to Read the Specifications and Features to Get the Most Value

Bigbattery27 Apr, 2026Business

Whether you’re looking for a home battery backup to store your solar energy storage system’s surplus electricity or you simply need a UL grid-tied solution to keep your home powered in the event of natural disasters or blackouts, there are a lot of details to sift through. The process of selecting a home battery backup system can seem quite onerous.

When and Why an Off-Grid Solar Battery Is Necessary

Bigbattery27 Apr, 2026Business

Many homes in this country are powered by supplemental energy systems such as solar. Most lease them, fewer own them, and perhaps even fewer yet have those systems connected to an off-grid solar battery system. For homes that remain on the grid, a battery energy storage system of this nature is not entirely imperative. For those that are off-grid, battery systems are. Here’s why they’re necessary and what they offer.

Why Lithium Marine Batteries Are a Smarter Fit for Confined Boat Hulls

Bigbattery23 Apr, 2026Business

Boat owners know that available space is always at a premium. From storage lockers to engine compartments, every square inch counts—and battery compartments are no exception. In many vessels, especially smaller boats, batteries end up in tight, enclosed areas with limited ventilation. That makes heat management and efficiency critical for long-term performance. This is where lithium marine batteries excel, offering clear advantages over traditional lead-acid systems.
