Designed to Fit. Engineered to Perform.

The InSight Series™ is the first scalable, drop-in replacement lithium battery built from the ground up by a team of battery experts. We developed InSight by looking at where lithium batteries fell short and resolving to design a battery that solved the issues early lithium solutions brought to the market, rather than repurposing an existing product. The result is a quality lithium battery with an intelligent, intentional design.

The Features that Make InSight Superior

InSight features all the benefits of lithium batteries – longer life, no maintenance, faster charging – with even more intelligent built-in features. From its superior battery design to its one-of-a-kind BMS, InSight batteries offers exclusive advantages you won’t find in competitive products, giving you an exceptional return on investment for years to come.

SuperSmart BMS

InSight Series™ features an elegant BMS that provides precision balancing within a single battery and between batteries in a parallel system without the need for charging batteries individually.

Intuitive Software

Our proprietary software with learning algorithms makes InSight the only lithium battery capable of calculating state of charge and state of health that gets even more accurate over time

Intelligent Cooling

Unlike other lithium batteries that can trap heat, the InSight Series uses a carefully engineered cooling management system to quickly remove heat from inside the battery during conditions of high discharge and recharge currents. This prevents overheating of critical components and extends the life of the battery.

Scalable System Design

InSight batteries offer freedom and flexibility so you can scale your system to provide increased power and energy (up to 300Ah) as needed.

Easy Installation

The innovative design of our InSight battery makes it easy to install. Plus, they use the connections you're already accustomed to when connecting in parallel.

State-of-the-Art Construction

InSight was built to the highest industry standards from the inside out. InSight Series™ batteries undergo rigorous quality control checks and inspection at each stage of assembly to ensure a reliable, consistent, and high-quality product.


InSight batteries are made with the best components needed to pass the stringent requirements of UL certification, and manufactured to the highest standards, offering superior performance and long life.

Quality You Can Depend On

You can customize a lot about your equipment, but you can’t customize your battery. That’s for us to do, and you can trust that we did it right. Not only are InSight batteries built smarter, but they’re also built to the highest quality standards.
