Curtis Instruments Acuity


This Acuity component is a battery mounted device that measures, stores and communicates the status of the batteries to the controller. The device calculates the state of charge based on amp hours consumed instead of basing state of charge on battery voltage alone. This system gives a very accurate indication of state of charge of your batteries.

This device works with lead-acid batteries only. This system is an option for the golf car systems that use lead-acid batteries and the system is also an option offered to our OEM customers.

Please contact us at more information.
