algorithms designed to optimize both daily battery capacity and overall battery life. The charger is convection
cooled with no moving parts, sealed, and designed to provide maximum reliability. The universal AC input
enables the charger to be used with a wide range of AC voltages and frequencies, and the charger includes
high efficiency and power factor correction. Interface features of the charger include four (4) LEDs. The
1425W charger models are also capable of automatic multi-voltage DC charging, which enables automatic
DC output voltage detection and adjustment based on the battery pack connected to it.
The charger features Bluetooth®wireless communication, which enables a smart phone or tablet running the
ChargerConnect™app to be used to:
View the real-time charge cycle status
Download charge cycle history records from the charger
Upload charge cycle history records to the Cloud for access anywhere in the world
Select the active battery profile
Download new battery profiles from the Cloud
Upload battery profiles to the charger
The charger was factory-configured with the active battery profile that was requested as part of the original
order from Lester Electrical. The charger was also factory-configured for mounting on-board a battery-
powered vehicle/machine or for off-board use in a shelf or portable application per the original order from
Lester Electrical. Before (1) using the charger for the first time or (2) using the charger with a battery pack of
a different type or capacity, use the ChargerConnect app to verify that the proper active battery profile is
selected and that the system settings match your application (see Section 8).
CAUTION: PRIOR TO OPERATING THE CHARGER, VERIFY THAT THE ACTIVE BATTERY
PROFILE MATCHES THE BATTERIES IN YOUR EQUIPMENT AND THAT THE SYSTEM SETTINGS
MATCH YOUR APPLICATION BY USING A SMART PHONE OR TABLET AND THE
CHARGERCONNECT APP AS DESCRIBED IN SECTION 8.
2. RECEIVING AND INSTALLING THE CHARGER

3. BATTERY TYPE
This charger contains multiple battery profiles for different battery types (including wet/flooded, AGM, and gel)
and capacities of batteries. The charger was factory-configured with the active battery profile that was
requested as part of the original order from Lester Electrical. Before (1) using the charger for the first time or
(2) using the charger with a battery pack of a different type or capacity, use the ChargerConnect app to verify
the proper active battery profile is selected. If the proper battery profile is not available on the charger, the
ChargerConnect app can be used to download the appropriate battery profile from the Cloud. If the battery
type you will be charging is not available via the ChargerConnect app Cloud (for example, a specific lithium-
ion brand or chemistry), contact Lester Electrical for more information. See Section 8 for additional details.
If the active battery profile is changed, mark the charger ratings label or add an additional label or tag.
CAUTION: THIS CHARGER IS FOR USE ONLY WITH BATTERY SYSTEMS OF THE SAME TYPE AS
THE ACTIVE BATTERY PROFILE. BATTERIES IMPROPERLY MATCHED WITH THE CHARGER MAY
BURST CAUSING PERSONAL INJURY AND DAMAGE TO THE BATTERIES OR CHARGER.
Battery manufacturers frequently use the same battery cases for different battery types. Wet/flooded
batteries have removable cell caps. Water electrolyzed by discharging and charging the battery is replaced
through these openings. Sealed batteries are generally distinguished by non-removable cell caps. The
physical appearance of the battery case is frequently the same as a wet battery, though the cell caps are
generally not removable. Refer to the battery manufacturer's information panel on the battery case to
determine the type battery you have. If the information panel is missing or not legible, do not use the battery.
If you have questions regarding which battery profile to select for use with your particular battery pack,
contact your dealer for assistance.

Summit Series II ® 13 of 28 User’s Manual
4. OFF-BOARD (SHELF) VERSUS ON-BOARD (BUILT-IN) CHARGERS
This section describes how the charger operates when the charger type is set to Off-board or On-board.
Based on your application, this setting can be changed via the ChargerConnect app under “System Profile”
(see Section 8).
The charger was factory-configured with the active battery profile that was requested as part of the original
order from Lester Electrical. The charger was also factory-configured for mounting on-board a battery-
powered vehicle/machine or for off-board use in a shelf or portable application per the original order from
Lester Electrical. Before (1) using the charger for the first time or (2) using the charger with a battery pack of
a different type or capacity, use the ChargerConnect app to verify that the proper active battery profile is
selected and that the system settings match your application (see Section 8).
4.1 Off-Board Chargers
Off-board chargers are designed to be used in shelf or portable applications. If the AC input plug is
connected to 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.
4.2 On-Board Chargers
On-board chargers are designed to be mounted on electric vehicles/equipment. If 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.
5. AC INPUT
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK OR FIRE, DISCONNECT AC POWER
FROM THE CHARGER BEFORE INSTALLING OR REMOVING UNIT.
The charger has an AC input rating of 100-240 volts, 50-60 hertz, single-
phase. The charger has an AC operating range of 85-265 volts, 45-65
hertz. Below 108 volts, the charger may reduce output power.
The charger is equipped with an IEC 60320 C16 inlet for the AC input
power as shown. This allows the AC power cordset to be selected with a
proper plug compatible with local electrical codes. The AC power cordset
must be a minimum of 14 AWG (2.0 mm2) for proper operation. An AC
cord clamp is also included to retain the AC power cordset IEC 60320 C15 connector. Loosen the screw on
the side of the clamp as shown before inserting the C15 connector. Fully insert the connector into the charger
inlet and then tighten the AC cord clamp screw to secure the AC power cordset to the charger.
The charger must be grounded to reduce the risk of electric shock and is equipped with an IEC 60320 C16
inlet having an equipment-grounding conductor and a grounding socket. The installed AC power cordset
must be plugged into an outlet that is properly installed and grounded in accordance with all applicable
electrical codes and ordinances.
If this charger includes the UL Listed symbol on its ratings label, it is provided with a cord set for connection to
outlets operating at nominal 120 volts (or 240 volts as appropriate). If the input plug does not fit the power
outlet, contact Lester Electrical for the proper cord set terminating in an attachment plug of the proper
configuration for the power outlet.

Summit Series II ® 14 of 28 User’s Manual
DANGER: NEVER ALTER THE AC POWER CORDSET OR PLUG PROVIDED. IF IT WILL NOT FIT
AN OUTLET, OBTAIN THE CORRECT CHARGER IEC AC POWER CORDSET FOR THE OUTLET, OR
HAVE A PROPER OUTLET INSTALLED BY A QUALIFIED ELECTRICIAN. IMPROPER CONNECTION
CAN RESULT IN A RISK OF ELECTRIC SHOCK.
If an extension cord is necessary, it must be a 3-conductor, No. 10 AWG (6.0mm) minimum, heavy-duty cord
with ground. It must also be in good electrical condition and as short as possible, 25 ft (7.6m) maximum.
Make sure that the pins on the plug of the extension cord are the same number, size, and shape as the AC
power cord plug on the charger. The use of an improper extension cord could result in a risk of fire or
electrical shock.
Locate all cords so that they will not be stepped on, tripped over, or otherwise subjected to damage, stress, or
accidentally disconnected.
CAUTION: VERIFY THAT THE AC POWER CORDSET IS FULLY ENGAGED IN THE IEC INLET AND
CANNOT BE PULLED LOOSE BEFORE USING THE CHARGER.
DANGER: RISK OF ELECTRIC SHOCK! CONNECT THE AC SUPPLY CORDSET DIRECTLY TO A
GROUNDED, 3-WIRE OUTLET. DO NOT TOUCH UNINSULATED PORTION OF DC OUTPUT
TERMINALS OR BATTERY TERMINALS. REPLACE DEFECTIVE CORDS, WIRES, OR CONNECTORS
IMMEDIATELY.

pack of a different type or capacity, use the ChargerConnect app to verify that the proper active battery profile
is selected (see Section 8).
6.1 Auto Voltage Mode
The 1425W 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 36V and 24V 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 connected to a 1425W charger model with t he ChargerConnect app (see Section 8), 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: A battery profile can be assigned for 36V and 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 36V and 24V nominal
battery packs where the battery packs are of different types and/or capacities so using the “Scalable
Profile” mode is not appropriate.

Summit Series II ® 15 of 28 User’s Manual
SCALABLE PROFILE: The nominal DC voltage of the “Active Battery Profile”is automatically scaled
to 36V or 24V based on the connected battery pack.
NOTE: If the charger is currently se t 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 in the ChargerConnect app.
When Auto Voltage Mode is active (either “Per Voltage Profiles” or “Scalable Profile”) the ChargerConnect
app “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”.
6.2 DC Output Cordset
The DC output cordset includes a connector, plug, or terminals. The polarity of the charger DC
connector/plug/terminals must be the same as the battery connector/receptacle/terminals. The BLACK DC
cable must be connected to the battery negative (-), and the WHITE or RED DC cable must be connected to
the battery positive (+). The charger will not operate if the polarity is reversed.
WARNING: CHARGER DC CORDSET MUST HAVE A MINIMUM OF 10AWG WIRE SIZE FOR
PROPER HEAT DISSIPATION. TO PREVENT RISK OF FIRE, DO NOT USE SMALLER GAUGE WIRE.
The DC cordset attaches to the external DC terminal block on the charger. Remove the touch proof cover (if
pre-installed) to expose the DC terminal block as shown in Figure 6.2-1. Based on the DC cordset
connector/plug/terminals, use Table 6.2 to determine the correct Configuration Number, and then attach the
DC cordset wires as shown in Figure 6.2-2. Torque the screws for the battery connections to 18 in-lbs (2.0 N-
m) and the lockout and external temperature sense connections to 12 in-lbs (1.35 N-m). Place the strain
relief over the DC cordset cable/wires. When individual wires are used for on-board applications, place the
foam rubber gasket that comes on the cordset under the strain relief, center the wires, and then tighten the
strain relief nuts and torque them to 12 in-lbs (1 N-m). This prevents the wires from getting pinched on the
side of the strain relief when tightened. Replace the terminal block cover, and torque the cover screws to 9
in-lbs (1 N-m).

7 VEHICLE LOCKOUT CONTROL
The charger lockout/interlock control signal can be interfaced with the vehicle/equipment to prevent
use/movement of the vehicle while the charger is in use. The lockout control signal, available on Terminal 2
on the DC terminal block (see Figure 6.2-1), is internally pulled high through a 10k ohm resistor to battery
positive (+) when lockout is not active and is pulled low to < 1 Vdc when lockout is active. The lockout control
signal is typically interfaced with the vehicle motor speed controller. If you are uncertain of how to interface
the lockout control signal with your vehicle, please contact your vehicle dealer.
If the charger is configured for on-board use, the lockout control signal will be active while AC power is
applied to the charger. If the charger is configured for off-board use, the lockout control signal will be active
while a valid battery is connected to the charger. Based on your application, you can configure the charger as
on-board or off-board via the ChargerConnect app under “System Profile”(see Section 8).

CAUTION: CHANGES OR MODIFICATIONS NOT EXPRESSLY APPROVED BY THE PARTY
RESPONSIBLE FOR COMPLIANCE COULD VOID THE USER'S AUTHORITY TO OPERATE THE
EQUIPMENT.
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
part 15 of the FCC and ICES-003 Rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this equipment in
a residential area is likely to cause harmful interference in which case the user will be required to correct the
interference at his own expense.
9. EXTERNAL PORT
The charger has an external port with a sealed DB9 (DE9) connector
located near the DC terminal block which is used for the remote LED
and/or CAN communication cable assemblies. When this port is not
being used, leave the protective cover over the connector to keep
moisture and debris out of the connector.
When mounting the charger on-board a vehicle where the
charger LEDs are not visible, a remote LED cable assembly
can be used. Attach the remote LED cable assembly to the
external port on the charger and hand tighten the connector
mounting screws. The LED end of the cable assembly is to
be rear mounted through a hole on the vehicle or it can be
attached to a panel which mounts to the vehicle. Install the
remote LED assembly as shown. Remote LED blink patterns
are detailed in Section 12.3.
10. PROPER CARE OF DEEP-CYCLE LEAD-ACID MOTIVE POWER BATTERIES
Motive power battery packs are subjected to severe deep-cycle duty on a daily basis. Although these
batteries are designed to withstand such duty, the following precautions must be observed to obtain good
performance and maximum cycle life.
CAUTION: ALWAYS WEAR PROTECTIVE EYE SHIELDS AND CLOTHING WHEN WORKING WITH
BATTERIES. BATTERIES CONTAIN ACIDS WHICH CAN CAUSE BODILY HARM. DO NOT PUT
WRENCHES OR OTHER METAL OBJECTS ACROSS THE BATTERY TERMINAL OR BATTERY TOP.
ARCING OR EXPLOSION OF THE BATTERY CAN RESULT.
1. When installing new batteries, be sure the polarity of each battery and the overall battery pack is correct.
Otherwise, battery and/or charger damage can result.
2. New batteries should be given a full charge before their first use because it is difficult to know how long
the batteries have been stored.
3. New batteries and older batteries that have been in storage are not capable of their rated output until they
have been discharged and charged a number of times. Consult the manufacturer of your batteries for
more information.
External Port

Summit Series II ® 20 of 28 User’s Manual
4. DO NOT EXCESSIVELY DISCHARGE THE BATTERIES. Excessive discharge can cause polarity
reversal of individual cells resulting in complete failure shortly thereafter.
5. Maintain the proper electrolyte level of wet (flooded) batteries by adding water when necessary. Distilled
or deionized water is best for battery life. Never allow the electrolyte level to fall below the top of the
battery plates. Electrolyte levels lower during discharge and rise during charge. Therefore, to prevent the
overflow of electrolyte when charging, it is mandatory that water be added to cells AFTER they have been
fully charged –do not overfill. Old batteries require more frequent additions of water than new batteries.
6. Hard crystalline sulfates form when batteries in storage are not maintained in a charged active state.
Internal self discharge can bring about the start of this condition in as little as three days in warm
temperatures. Batteries not maintained and allowed to sit in storage will self discharge, sulfate and lose
capacity. Repeated charging without using the batteries between charges can recover some of the lost
power, range, and life, but some permanent loss should be expected.
7. Cold batteries require more time to fully charge. When the temperature falls below 65°F, the batteries
should be placed on charge as soon after use as possible.
8. The tops of batteries and battery hold downs must be kept clean and dry at all times to prevent excessive
self discharge and the flow of current between the battery posts and frame. Electrolyte spilled on
batteries never dries or evaporates.
9. All connections to batteries must be maintained clean and tight. Due to heating and discharge rates,
bolted connections loosen over time. Re-tighten the connections twice yearly to the torques specified by
the battery manufacturers.
10. Follow all operating instructions, cautions, and warnings as specified in this manual, on the charger, in the
battery manuals, and in the vehicle manuals.
10.1 Personal Safety Precautions
1. Have someone within the range of your voice and close enough to quickly come to your aid when you
work near a lead-acid battery.
2. Ensure that ample fresh water and soap are nearby in case battery acid contacts your skin, clothing, or
eyes.
3. Wear complete eye and clothing protection. Avoid touching your eyes while working near a battery.
4. If battery acid contacts your skin or clothing, wash immediately with soap and water. If acid enters your
eye, immediately flush your eye with running cold water for at least 10 minutes, and get medical attention
immediately.
5. NEVER smoke or allow a spark or flame to be in the vicinity of a battery.
6. Be extra cautious to reduce the risk of dropping a metal tool onto a battery. It could spark or short circuit
the battery or other electrical components that could cause an explosion.
7. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a
battery. A battery can produce a short-circuit current that is high enough to cause a severe burn.
8. NEVER charge a frozen battery.
11. CHARGER OPERATION
WARNING: TO REDUCE THE RISK OF AN ELECTRIC SHOCK, CONNECT ONLY TO A SINGLE-
PHASE, PROPERLY GROUNDED (3-WIRE) OUTLET. REFER TO GROUNDING INSTRUCTIONS.
CAUTION: MAKE SURE THE BATTERY IS A RECHARGEABLE DEEP-CYCLE BATTERY WITH THE
PROPER RATED VOLTAGE FOR THIS CHARGER.
DANGER: TO PREVENT ELECTRICAL SHOCK, DO NOT TOUCH UNINSULATED PARTS OF THE
CHARGER DC OUTPUT CONNECTOR, BATTERY CONNECTOR, OR BATTERY TERMINALS. MAKE
SURE ALL ELECTRICAL CONNECTORS ARE IN GOOD WORKING CONDITION. DO NOT USE
CONNECTORS THAT ARE CRACKED, CORRODED, OR DO NOT MAKE ADEQUATE ELECTRICAL
CONTACT. USE OF A DAMAGED OR DEFECTIVE CONNECTOR MAY RESULT IN A RISK OF
OVERHEATING OR ELECTRIC SHOCK.
