1.1.1 -Battery Management System
Every HLX+ battery contains a BMS that helps protect it from over voltage charging/discharging,
over current charging/discharging, and extreme temperatures while charging and discharging.
While this system is robust, batteries must be installed using appropriate inverter charge and
charge controller settings, devices to protect them from open photovoltaic (PV)/solar panel voltage,
and other high voltage charging sources. Failure to adhere to proper installation requirements will
void the warranty and may damage the system.
1.1.2 KiloVault iT, the Bluetooth Monitoring Mobile Applica-
tion
The KiloVault iT smartphone Bluetooth app enables you to view general information about the se-
lected individual battery. It can help troubleshoot when attempting to detect the cause of the battery
bank going off-line. The app is available for free download for both Android and iPhone phones.
Each battery is identified by a unique name assigned at the factory.
1.1.3 HLX+Bridge (Sold Separately)
The features the HLX+ Bridge are:
1. Viewing information about your entire battery bank and individual batteries
2. Enable 4x4 bank configurations in cold climates.
3. Update the HLX+ firmware.
1.1.4 Heating System
The 1200 HLX+ heater is 64 W. The 2400 HLX+ heater is 96 W, and the 3600 HLX+ heater is 192
W. The heater is powered by charging current, not by the battery. The battery does not self-dis-
charge to warm itself.
In all of the batteries the heater starts at an internal temperature of 0°C (32°F) and stops at an
internal temperature of 5°C (41°F). At external temperatures below -30°C (-22°F), the heat dissipa-
tion is too great to bring the battery up to temp.
It will take about 1.5 to 2 hours to warm the battery from an internal temperature of -20°C (-4°F) to
5°C (41°F).
When the batteries are charging with solar, it might take a longer time, depending upon the charger
output.

2. Safety Information
2.1 Symbols Used in This Manual
2.2 Warnings
High Voltage Risk. Improper use may cause personal injury or death.
Do not use a battery that appears damaged in any way.
All batteries present the risk of shock, use protective measures when handling.
When working with or installing batteries use electrically insulated gloves and tools.
Remove personal metal items such as watches, rings, bracelets, etc.
High voltage connections of batteries (configurations of greater than 36 V DC nominal) are dan-
gerous. DC voltages over 52 V can stop the adult human heart and a fully charged 48 V nominal
system is over this level. Use appropriate safety measures including the removal of metal personal
items and insulated gloves.
• A small risk of spark exists while making electrical connections.
• Ensure the installation area is free of explosive gases and liquids.
• Ensure the batteries are not installed in confined areas containing explosive substances.
This includes flammable fuel powered machinery, holding tanks, pipe fittings, and connectors. In
the unlikely event of a fire, when possible, first shut off the source of electricity. Class ABC extin-
guishers are recommended in close proximity to your power generating equipment and are best
suited for multipurpose fire types such as wood, flammable liquids, and electrical appliances.
Warning:
Indicates a condition that can cause personal risk or injury.
Caution:
Indicates a condition that can cause equipment damage.
Note:
Indicates points of interest of particular emphasis that make operation more
efficient or convenient.

3. Installation
3.1 Before You Install Your Batteries
1. When gathering your tools for your installation, please make sure that you have a digital multi-
meter with a 0.1 V accuracy. It will help you to verify battery polarity before you make any connec-
tions. You can also use the multimeter to ensure that your batteries are at the same voltage.
2. Please write down and save the serial numbers of your batteries along with the rest of your
system information. The serial numbers are on a silver barcode sticker and start with the letters
“MWT”. If you have already downloaded and installed the KiloVault iT battery monitoring applica-
tion, also write down and save the battery names. Make sure you set aside the included terminator
plugs as they can easily be misplaced.
3. Each battery must be commissioned by individually charging it to exactly 14.1 V before placing it
into operation with other batteries. Otherwise, the batteries will be fully charged or fully discharged
at different times and could cause a low voltage or high voltage disconnect.
A. You will see 14.1 V while the battery is still on the charger and actively charging. When
charging is finished and the charger shuts off or the battery is disconnected, the voltage will
slump to 13.3 > 13.6 V. This is normal. The battery is still fully charged.
B. Due to transportation regulations, lithium batteries cannot be shipped fully charged. As a
result, if you have purchased more than one battery for your system all batteries must be
fully charged to exactly 14.1 V before using.
C. Many automotive-type battery chargers will not reach 14.1 V. Please check charger spec
ifications when selecting your charge. You can contact your KiloVault® distributor for a list
of recommended chargers.
D. An acceptable charger:
• Must be a 12 V charger.
• Maximum charge voltage - 14.1 V.
• Must have Equalization disabled.
• 1200 HLX+ maximum charge amperage - 80 A.
• 2400 HLX+ maximum charge amperage - 150A.
• 3600 HLX+ maximum charge amperage - 150A.
• Charger must taper the amps as the battery approaches 14.1 V.
E. After batteries are fully charged and disconnected from the charger, allow them to rest for
a minimum of two hours. During this time, the voltage will relax, even as low as 13.3 V.
Your batteries are still fully charged. This is normal.
3.2 Location
Locate your battery bank in a place that is dry and as well protected from extreme temperatures as
possible. No ventilation is required as these do not off-gas like lead-acid batteries do.
4

HLX+ batteries must be placed flat on their bottoms. Any other orientation will void the warranty.
Also, do not stack them one directly on top of another.
Batteries warm up while in use. Please consider your local average and seasonal temperature
when positioning your battery bank. If they will be in a warmer environment, you may want to leave
a minimum of one inch spacing between each of the batteries.
If they will be subjected to cold temperatures, you may want to place them as closely as possible
to each other. Consider adding insulation or an insulated enclosure around the batteries if they will
be exposed to temperatures that approach 32°F (0°C). The BMS will not allow charging when the
internal temperature is below freezing, and they will try to warm themselves using the charging
current Using insulation when it is cold will maintain more of the heat generated during normal
charging and reduce the chance of the BMS shutting the battery down to protect the battery cells.
Please note battery capacity is reduced by 20% as its internal temperature falls between room
temperature (approximately 77°F (25°C) and just above 32°F (0°C).
Please remember to remove the insulation in warmer months. Overheating the batteries will short-
en their life and the BMS will shut down the battery in temperatures above 149°F (65°C).
3.3 Cabling
All wire must be the appropriate gauge and construction to handle the loads that will be placed
upon it. Heavy gauge, fine stranded copper wire is the industry standard. A minimum of 2/0 or 4/0
AWG copper cable is recommended for battery interconnect cables.
The cables connecting batteries in series into rows must be the same length. The cables connect-
ing the rows in parallel must be the same length. The home run cables to the inverter must be the
same length. Cables of different lengths will cause voltage differences in your battery bank. The
rows in your battery bank must be kept within 0.2 V of each other to ensure that they work correctly
and that large currents between rows aren’t generated.
If your battery bank suddenly shuts down as one or more rows approaches fully charged or fully
discharged, it is likely either the batteries are not all at the same state of charge or, if they are mea-
sured with a multimeter to be all the same voltage, the voltage drop across the cables connecting
the rows is not equal. Also use the voltmeter to make sure that the voltage drops across each
battery interconnect is very close.
Torque all bolts and battery terminals to between 7.38 and 8.11 ft-lbs (88.51 to 97.36 in-lbs OR 10
to 11 nm). Terminals left insufficiently tightened will lead to overheating, melting the battery termi-
nals and potentially causing a fire. Be careful when using thin washers. You may think you're ap-
plying sufficient torque, but if the washers are too thin, the cable lugs can still move. Add additional
washers until you can tighten, and the cable lugs cannot move.
3.4 Congurations
The KiloVault® HLX+ series of batteries can be used in 12 V, 24 V, 36 V, and 48 V configurations
where one, two, three or four batteries are connected in series, plus to minus, in a row. The maxi-
mum number of batteries in a bank is sixteen, 4 in parallel strings of 4 batteries in series. Each row
of batteries must be kept within 0.2 V of each other or the battery bank may prematurely shut down
during charging and discharging. There are configuration limitations depending on the temperature
range of the installation location and whether or not you are using the HLX+ Bridge. The HLX+
Bridge helps the HLX+ batteries coordinate their heaters.
2022 5

3.4.1 With the HLX+ Bridge (Sold Separately)
The HLX+ Bridge allows the batteries to coordinate their heaters beyond a single string or 4 or 4
single batteries in parallel. If you are using the HLX+ Bridge with your bank of HLX+ batteries,
then you can use the maximum configuration of 4 parallel strings of 4 batteries in series, even if
the installation location will go below freezing.
3.4.2 Without the HLX+ Bridge
If you are not using the HLX+ Bridge, and the installation location will stay above freezing (32°F
(0°C), then the HLX+ batteries can be wired together up to 4 parallel strings of 4 batteries each.
The KiloVault HLX+ BRIDGE is used with HLX+ series batteries. The KiloVault HLX+ BRIDGE
is integrated with smart touch screen, management control board, interface ports, and Blue-
tooth. Through CAN/RS485 communication, it can monitor, manage and control The KiloVault
HLX+ series batteries. In multiple battery series-parallel battery bank, there are monitoring,
protection and data checking functions, and can use the HLX+ BRIDGE to upgrade the bat-
tery rmware. It is commonly used in battery systems of residential storage, RV, Off grid and
Grid tied applications.
6

HLX+ in Series
HLX+ in Parallel
HLX+ Batteries are paralleled by wiring from individual HLX+ Batteries to DC busbars
or plates, which may be located in a DC combiner box or the inverter’s power panel.
All wire lengths from each HLX+ Battery to common busbars or plates should be identical
in length and gauge in order to balance the load across (all) HLX+ Batteries in the installa-
tion.
Warning:
All wire lengths from each HLX+ Battery to common busbars or plates should
be identical in length and gauge in order to balance the load across (all) HLX+
Batteries in the installation.
2022 7

3.4.3 Communications and Network Preparation
Network distribution.
Communication and Monitoring is available via the HLX+ PLUSNET. The KiloVault HLX+
PLUSNET enables multiple lithium batteries to operate as “one system” for data measure-
ment, typically with a host battery leading the data from a linked set of lithium batteries.
There is a lot more data than just voltage and current shared over the CANbus.
Each HLX+ battery comes with a terminator plug, and an RJ45 dust cover for networking
communication set-up. For battery with self-distribution feature, when 4pcs are in series or
4pcs are in parallel, there is no need for the Bridge, the rst battery can act as the Leader
Battery. See connection diagram as below:
1)Connect the COM port to the COM port between the batteries
2)Insert the resistor plug into the COM port of the last battery.
3.4.4 Connecting the KiloVault PLUSNET BMS
network
To connect the PLUSNET communication network you will need:
CAT5 cable with RJ45 connectors, straight wiring (not included).
One termination resistors (supplied with each HLX+ Battery).
8

In a string of batteries, the two batteries at the ends of the communication chain will have a ca-
ble occupying only one of the “daisy-chaining” ports in the HLX+ battery. On each of these two
batteries, the communication port not occupied by a cable will need a 120Ohm terminator plug
installed in the open port (see photo). One terminator plug is included per HLX+ battery.
Each HLX+ battery includes two RJ45 ports, compatible with CAT5 (or greater) cable. These
ports are used for connecting between HLX+ batteries in a battery bank (“daisy-chaining”).
These two ports can be identied as the “daisy-chaining” ports because they are in close prox-
imity to one another.
If you are not using the HLX+ Bridge, and the installation location will go below freezing, then the
configuration is limited to 4 HLX+ in parallel or 4 HLX+ in series, but not both, because, without the
Bridge, the HLX+ cannot coordinate their heaters beyond these configurations.
3.4.5 Storage Mode
The battery can be switch between Active Mode and Storage Mode using the KiloVault iT app.
The battery is shipped in Storage Mode, to switch from Storage Mode to Active Mode long
press the power button for 5 seconds.
Prior to long periods of storage, disconnect the battery from the system, and select Storage
Mode form the KiloVault iT app. In Storage Mode the battery has a low self-discharge rate and
can hold the charge for a longer period of time.
Note:
In Storage Mode, Bluetooth will be turned off making the battery not visible on
the KiloVault iT app. To activate the battery long press the power button for 5
seconds
Caution:
Please leave the battery in Storage Mode during installation. DO NOT switch
the battery to active mode until making sure all the connections are correct and
secure. Connecting active batteries to the system may trigger the short circuit
protection of the battery.
2022 9

3.4.6 - Screens & Operation
Note:
The battery leaves the factory in Storage Mode. Please switch the battery to
Active Mode by a pressing the battery power button for 5 seconds after con-
necting the battery to the system for the first time
Note:
Paralleled batteries can be switched to Active Mode simultaneously by a 5 sec-
ond long press on any battery.
To switch the battery to Storage Mode simultaneously, please enable the
communication between batteries and use the KiloVault iT app’s Storage Mode
on the first battery. Otherwise please disconnect the batteries and use the
KiloVault iT app’s Storage Mode to switch each battery to Storage Mode.
Storage Mode will turn of the Bluetooth function on each battery reducing the self discharge
rate and can hold a charge for a longer period of time. The battery will not be visible using the
KiloVault iT app and will require a reset by a 5 second long press of the power Button.
PlusNET will disconnect communication between each battery to reduce the self discharge of
each battery. Bluetooth will still be active allowing monitoring using the KiloVault iT app. You
can reactivate PlusNet by using the KiloVault iT app. If you do not wish to connect the com-
munication cables between batteries it is recommended that you turn PlusNet off to conserve
power.

4.4 Generator/Automatic Generator Control Settings
The battery related settings for using a generator and/or an automatic generator start/stop (AGS)
control with HLX+ batteries can usually be found in the inverter/charger and solar charge controller
settings.
Some generators and/or AGS have settings for 2 minute, 2 hour and 24 hours (or similar duration)
start voltages. They set time limits the battery voltage can sit at before activating the generator.
They are related to the Low Voltage Disconnect/Cut-Off voltage and the Recharge/Re-bulk volt-
age. Expect to adjust any or all of them over time to get exactly the generator behavior you wish.
Depending on the make and model of the generator or AGS, you may need to have more spacing
between these settings.
• 2 minutes - Set just above the inverter/charger Low Voltage Disconnect (12.25 V) so the gen-
erator starts before the inverter stops inverting.
– Start at approx. 12.3 V and adjust as necessary.
• 2 hours - Set above the 2 minutes volts.
– Start at approx. 12.4V.
• 24 hours - Set just below the Recharge/Re-bulk voltage. If the Recharge/Re-bulk setting
hasn’t already started the generator at this time, the generator will start.

does not drive any battery behaviors / performance. To get back to your list of batteries, tap the
arrow in the lower left corner of the screen.
From the Basic screen you can also get detailed information on battery current alarms, individual
battery cells and if you wish, rename your batteries.
There can be as much as 0.3 V difference between the volts shown in the app and the volts mea-
sured at the terminals, especially in the middle of a charge / discharge cycle. At the beginning and
end of the voltage range, the values converge.
To get information on individual cells, first select the “ADVANCE” tab in the lower portion of the
Battery’s Information screen. A login dialog will appear. Type “1234” into the login dialog and tap
“confirm”. A button called “Battery Information” will appear. Tap that button. A semi-transparent
screen will appear with 8 button-like icons. They indicate if the battery has any active alarms. The
indicators are normally green. They will be red if there is an alarm. They are High Voltage (HV),
Low Voltage (LV), Overcurrent Charging (OCC), Overcurrent Discharging (OCD), Low Temperature
Discharging (LTD), Low Temperature Charging (LTC), High Temperature Discharging (HTD), High
Temperature Charging (HTC).
Below the alarm indicators are 4 battery shaped icons. They represent the 4 cells that make up
the battery. Their color does not indicate anything. They are always the same color. Below each
battery icon is a number showing each cell’s voltage in mV (millivolts). The color of the numbers do
not mean anything. They’re always the same color. The difference between the highest and lowest
should be 300mV or less. Tap anywhere to dismiss this screen.
