AGV’s & Robotics

Bringing You Charging Solutions

Automation is occurring in every imaginable application. Robotics and AVG’s are creating efficiencies and transforming the way materials can move. Lester Electrical is supporting this innovation. Our mission is to make sure you have the battery power you need and you can count on us. Our Summit Series II charger will dependably and precisely charge batteries. We believe you deserve the best as you revolutionize core operations in healthcare, education, agriculture, food service, delivery systems and more.

Why Summit Series II?

A whole new world of charging.

Get the charging performance customers demand. Our proprietary Progressive DV/DT charge algorithm ensures your batteries are charged correctly. Our expert team works with top battery manufacturers to release charging profiles crafted to provide the best care for lead acid and lithium-ion batteries. These profiles are reviewed and tested in our C.E.C. (California Energy Commission) approved battery testing facility in Nebraska.

Less weight. Less space. More awesome.

We designed our newest chargers to be compact and lightweight. They have universal AC input and external DC and signal connections to allow for easy on-board integration. Save all that room for your engineers to design great features to include with that bot.

Tough. Really tough.

The IP66 rated Summit II doesn't worry about water or debris like dirt or mud. It is sealed and uses natural convection cooling - built without a fan. The chargers also have a wide operating temperature range for use in non-temperature controlled facilities.

Easy and Flexible.

Auto-voltage sensing models provide the ease of using one charger - including for customers with vehicles on different voltages. Plus the external terminal block makes changing the DC cordset a breeze. Now your only worry is determining how many new AGV's are needed on that order.

Smart maintenance and storage.

The charger stores charge cycle history records that can be accessed conveniently anytime using the ChargerConnect app. The charger has a sophisticated storage mode that will monitor battery voltage and time elapsed to ensure your batteries stay properly charged and cared if that robot isn’t used regularly.  No worries for your customers taking long holiday breaks, it will be ready to go when they need it.
