System Profiles

Charger Profiles Tab (all fields on this tab can be edited)

Charger ID – The ID of the charger. This field is factory set to be blank. The Charger ID can be set/modified on the “System Profile” and
“Dashboard” screens.

Vehicle ID – The ID of the vehicle that is paired with the charger (if applicable). The Vehicle ID is factory set to be blank. The Vehicle ID can be set/modified on the “System Profile” and “Dashboard” screens.

DC Cable Gauge (AWG) – The gauge of the DC cable in American Wire Gauge (AWG). This field is used to correctly compensate for the voltage
drop of the DC cable.

DC Cable Length (feet) – The length of the DC cable in feet [one direction only, not the sum of the length of both the positive (+) and negative (-) wires]. This field is used to correctly compensate for the voltage drop of the DC cable.

On Board check box – Checked for On-Board and unchecked for Off-Board.

On-Board chargers are designed to be mounted on electric vehicles/equipment. While the DC output is connected to a battery pack of the proper voltage, a
charge cycle automatically starts when the AC input plug is connected to AC power (unless a safety period of time has not passed since the successful
completion of the previous charge cycle). Disconnecting the DC output from the battery pack IS NOT REQUIRED to automatically start a new charge cycle.
Off-Board chargers are designed to be used in shelf or portable applications. While the AC input plug is connected to live AC power, a new charge cycle
automatically starts when the DC output is connected to a battery pack of the proper voltage. Disconnecting and reconnecting AC power while the DC output
remains connected to a battery pack WILL NOT automatically start a new charge cycle. Disconnecting the DC output from the battery pack IS REQUIRED to
automatically start a new charge cycle.

NOTE: A charger configured as On-Board can be used in a shelf or portable application where the DC output connector/plug is connected and disconnected from the vehicle, but a charger configured as Off-Board should not be used in an application where it is mounted on a vehicle with the DC output permanently connected to the battery pack because the charger will not automatically start a new charge cycle when AC power is applied to the charger.

Auto Voltage Profile – Only present on charger models that support Auto Voltage Mode. See the “Auto Voltage Mode” section below for details.

Lester Summit II Series Wireless App Battery Charger Auto Voltage Mode

Auto Voltage Mode

Select Summit Series II charger models support automatic multi-voltage DC charging, referred to as Auto Voltage Mode. Auto Voltage Mode
provides automatic DC output voltage detection and adjustment so that battery packs of nominal 48V and 36V (650W 48V, 36V, and 48-36V
models) or nominal 48V, 36V, and 24V (all 1050W models) can be charged with a single charger without any configuration changes needing to be
made to the charger when switching between battery packs of different nominal voltages.
When the connected charger model supports Auto Voltage Mode, the “System Profile” screen will include an “Auto Profile” selection box, which
provides the following three (3) options:

OFF: Single voltage mode – you MUST ensure that the nominal DC voltage of the “Active Battery Profile” for the charger matches the
nominal DC voltage of the connected battery pack.

PER VOLTAGE PROFILES:

o 650W 48V, 36V, and 48-36V models: A battery profile can be assigned for 48V and a different battery profile can be assigned for 36V. The proper battery profile is automatically selected based on the connected battery pack. This mode is primarily used when the charger will be charging 48V and 36V nominal battery packs where the battery packs are of different types and/or capacities so using the “Scalable Profile” mode is not appropriate.

o All 1050W models: A battery profile can be assigned for 48V, a different battery profile can be assigned for 36V, and yet a different
battery profile can be assigned for 24V. The proper battery profile is automatically selected based on the connected battery pack. This mode is primarily used when the charger will be charging 48V, 36V, and 24V nominal battery packs [or any combination of two (2) of these voltages] where the battery packs are of different types and/or capacities so using the “Scalable Profile” mode is not appropriate.

SCALABLE PROFILE:

o 650W 48V, 36V, and 48-36V models: the nominal DC voltage of the “Active Battery Profile” is automatically scaled to 48V or 36V based on the connected battery pack.

o All 1050W models: the nominal DC voltage of the “Active Battery Profile” is automatically scaled to 48V, 36V, or 24V based on the connected battery pack.

NOTE: If the charger is currently set to “Per Voltage Profiles” or “Scalable Profile” mode, and you set the “Auto Profile” selection box to “Off”,
you MUST ensure that the nominal DC voltage of the “Active Battery Profile” for the charger matches the nominal DC voltage of the
connected battery pack via the “Battery Profiles” screen.

When Auto Voltage Mode is active (either “Per Voltage Profiles” or “Scalable Profile”) the “Dashboard” screen provides the status of the proprietary algorithm that executes at the beginning of the charge cycle by displaying the “Auto Battery Voltage Detection” as a status percentage and the “Detected Battery Pack Voltage” (see the “Dashboard” section).

Device Profiles Tab
 Lists all battery profiles available on your smart phone or tablet (device).
 Upload battery profiles that reside on your smart phone or tablet (device) to the connected charger via the green arrow buttons
o You will be required to select the “Profile Slot Number”. Summit Series II chargers can store up to 20 battery profiles locally. The
local battery profiles are stored in “Slots”, which are numbered 0-19. You can either select an empty Slot to store the battery profile
that will be uploaded to the charger or a Slot that currently contains a battery profile, in which case the battery profile will be
overwritten.NOTE: When a battery profile is uploaded to the connected charger, it automatically becomes the Active profile on the charger.
