The InSight Difference

What Makes InSight Unique?

Fits Like A Glove

The InSight 48V battery is a GC2 size drop-in replacement. It's built specifically to fit your golf car. No need to modify the battery trays, and no extra components or retro-fit kits are needed. Simply remove your old batteries, drop in, connect and go.

SuperSmart BMS

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

Intuitive Software

Proprietary software determines and manages regenerative currents – unlike any other battery solution. Avoids unnecessary battery disconnects.

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 over-heating of critical components, which also extends the life of the battery.

Parallel 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.

Safest Chemistry

The 48V InSight battery is a lithium iron phosphate (or LiFePO4) battery which is the safest lithium chemistry. It's also easier on the environment as no gasses are emitted.

State of the Art Construction

InSight was built to the highest standards from the inside out. Assembled in an advanced manufacturing facility, InSight Series™ batteries undergoes rigorous quality control checks and inspection at each stage of assembly to ensure a reliable, consistent, and high-quality product.
