Summit Series II Chargers

“Storage Mode” is a feature that comes with all Lester Electrical E-series, E-Series II, Summit and Summit II golf cart battery chargers. Once a manual charge session is complete, the charger goes into its “storage mode” feature when it remains connected to the golf cart and the AC Plug remains plugged into the wall.

When in storage mode, it will charge your batteries only when the following two situations occur (1) the battery voltage drops to a certain predefined voltage AND (2) 10-15 days have elapsed.

The positive wire from the charger must be connected to the first positive(+) terminal of the series battery pack (Battery #1), and the negative (-) wire must be connected to the last negative battery terminal of the circuit

Yes, Lester Electrical chargers have controlled current production so they can be used in application where the AC power sources is controlled by a GFCI wall output

The DC output plugs used by Lester Electrical have different current ratings, so its important to install a DC Cordset that is rated for the current that can be produced by the Lester Charger. Contact Lester Technical Support for DC Cordset current ratings before swapping DC Plugs

There is a minimum start voltage for all Lester Chargers. Lestronic 2 chargers require a DC Battery voltage of at least 70% of the rated voltage to initiate a charge sequence. Newer designed chargers such a Summit or E-Series require approximately 15 VDC for startup

Yes, the Lester Electrical Battery Charger can remained plugged into AC power for extended periods of time. It is a good idea to use an AC Outlet surge suppressor if the charger will be left unattended for long periods of time

Yes, All Lester Automatic battery chargers will terminate the charge sequence when the batteries being charged have met 100% capacity

Ferroresonant and SCR Chargers all use a transformers to produce the current required to charge batteries, so when these types of chargers are producing current, you will hear a low level “buzz” emitting from the charger. Summit and Summit II Chargers are “High Frequency” chargers that do not use transformers, so the LED Lights are used to verify proper operation

Red Flashing lights indicate a fault has occurred during the charge cycle. Quick Flashing (multiple flashes per second) are less critical than slow flashing (once a second). If the charger is flashing a slow red light, it has terminate the charger cycle and further troubleshooting steps are required

All manuals for Lester Chargers are available on our public website. It may be easier to search for this information using the Charger Series type (Summit II, E-series, etc.)

Depending on the state of battery discharge, it can take ups to 13 hours to fully charge a set of batteries

For extended battery life, the golf cart batteries should be charged after every use

Your batteries should always be charged with the cart in “Run” Mode.. Your golf cart should be switched to “Run” anytime you are using the cart or charging your batteries. “Tow” is only for long term storage (if you are planning to remove the batteries)

No, a charger rated at 36 volts will not charge a vehicle that is designed to run on 48 volts. If a 36VDC charger is connected to a 48 volt cart, the charger will display an “under voltage” error within 10 minutes.

Lester onboard chargers are typically installed within the battery compartment of golf cart, however, if space inside the compartment is limited, the charger can be installed in the tray behind the seats or in the compartment behind golf club holders.

The recommended battery profiles for different types of batteries are listed in the ChargerConnect™ App Users Guide which is located within the app (drop down menu>help) and on our public website

Battery profiles are series of charge instructions that battery chargers use to fully recharge the energy that is stored within a battery. Some batteries require Current – Voltage – Current (IEI) charge routines while others may require Current – Voltage – Float (IE) charge instructions

Battery profiles for Summit II chargers can be changed using the ChargerConnect App. Instructions for this procedure are listed in the users guide

The battery profiles can be viewed in the ChargerConnect App. See the Apps user manual for instruction to identify the profiles that are pre-loaded into each charger.

Yes, additional DC Cordsets can be purchased by contacting the Lester Electrical sales department at 402.477.8988

Yes, The standard Wet Cell battery profiles are used (IEI) and the maximum voltage is regulated by the lithium battery controller that is part of your power cell package

Controller Area Network (CAN) is a communication protocol that allows devices to communicate with each other without a host computer. Many electrical vehicles use this form of communication to monitor various systems o make the vehicle operate efficiently

All Summit II Chargers are CAN bus compliant

On-board Summit II Chargers are shipped with a universal mounting harness. The blue wire in the harness is used to control an external lockout device that will keep the vehicle from moving during a charge cycle. Please consult the vehicle manufacturer for information in regards to this connection

Multi-volt chargers will detect the battery pack voltage within 10 minutes of initial power up. To determine the status of this feature, establish the blue tooth connection using the ChargerConnect App, go to the dashboard and find the section below the fuel gauge that indicates a percentage of Auto Battery Voltage Detection. When this measurement reaches 100% the battery voltage has been detected

Onboard chargers initiate the charge sequence when AC voltage is detected by the charger. Shelf mode charger require the detection of DC voltage to initiate the charge

An accessory package may be purchased to install remote LED’s on any Summit II Charger. These remote LED’s allow the user access to valuable information if the charger is installed in an area without easy access
