Preparation
Before the installation and operation of the battery, it is recommended to have the following
equipment or tools available:
●Proper Protective Equipment
●Insulated Tool(s)
●Multimeter
●Battery Cable
●Battery Charger/Charge Controller
Battery Installation
Safe and reliable installation requires trained and certied technicians. Therefore, the purpose
of this section is only to serve as a guideline as all scenarios cannot be covered.
●DO NOT short-circuit the battery terminals. Doing so can cause current bursts and lead to
irreversible damage to the system and the battery.
●Please verify the polarity before connecting the wiring. Reversing polarity can and will de-
stroy the battery.
●Please use circuit breakers, fuses, or disconnects appropriately sized by a certied elec-
trician, licensed installers, or regional code authorities to protect all electrical equipment.
Inspection
Please check for visible damage including cracks, dents, deformation, and other visible abnor-
malities. The top of the battery and terminal connections should be clean, free of dirt and cor-

07
rosion, and dry. If any problems are detected with the battery, please contact us for assistance.
Refer to the last page of the manual for contact information.
Sizing Cables
Battery cables (sold separately) should be appropriately sized to handle the expected load.
Please refer to the following table for the ampacities of copper cables with dierent gauge
sizes.
Copper Cable Gauge Size (AWG/mm2) Ampacity (A)
14 (2.08) 20
12 (3.31) 25
10 (5.25) 35
8 (8.36) 50
6 (13.3) 65
4 (21.1) 85
2 (33.6) 115
1 (42.4) 130
1/0 (53.5) 150
2/0 (67.4) 175
4/0 (107) 230
The above values are from the NEC Table 310.15(B)16 for copper cables rated at 75°C
(167°F), operating at an ambient temperature of no more than 30°C (86°F). Lengths in excess
of 6 feet (1829 mm) may require heavier gauge cable to avoid excess voltage drop in under-
sized wiring.
Connecting Batteries in Bank
●DO NOT connect batteries in series. Doing so can cause catastrophic failure.
●DO NOT connect batteries with dierent chemistries, rated capacities, nominal voltages,
brands, or models in parallel.
●Please avoid excessive voltage dierence between parallel connected batteries to avoid
triggering the over-current protection.
●The cables between each parallel connected battery should be of equal length to ensure
that all batteries can work equally together.
●DO NOT connect more than 8 batteries in parallel.

08
To connect multiple batteries in parallel, rst connect the Positive Terminals of the batteries to
each other. Then, connect the Negative Terminals of the batteries to each other. Finally, con-
nect the Positive Terminal of the rst battery and the Negative Terminal of the last battery to the
system. This type of arrangement is used to increase the overall battery capacity while keeping
the battery voltage the same.
Securing Cable Connections
●Please secure all cable connections to the proper specication in order to ensure good con-
tacts between the cable lugs and the battery terminals. Over-tightening cable connections
can cause terminal breakage and loose cable connections can cause terminal meltdown
or re.
●Please use an insulated wrench to tighten the cable connections.
To ensure good contacts between the cable lugs and the battery terminals, please use the
appropriate number of washers to allow for as much thread engagement as possible without
bottoming out the terminal bolt. The correct number of washers can be determined by
hand-tightening the terminal bolt with just the cable lug in place and observing the gap that is
present. Use the number of washers needed so that the washer stack is slightly larger than
the observed gap.
It is important to ensure that the cable lug and the top surface of the terminal are in contact.
The washer(s) must be placed on top of the lug. Do not place the washer(s) between the
battery terminal and the cable lug as this can cause high resistance and excessive heating.
●Please use the included Long Terminal Bolts when needed to secure multiple cable lugs on
a single battery terminal.

09
Installation Environment
The battery should be installed in a clean, cool, and dry place, keeping water, oil, and dirt away
from the battery. The accumulation of these materials on the battery can cause current leakage,
resulting in self-discharge and a possible short-circuit. Sucient air ow must be provided to
prevent excessive heat build-up and to minimize temperature variation between the paralleled
connected batteries.
Battery Operation
●DO NOT overcharge or overdischarge the battery.
●DO NOT charge the battery at low temperatures below 0°C (32°F) and discharge the battery
at high temperatures above 140°F (60°C).
Activating Battery
The battery is shipped in shelf mode. Before using the battery for the rst time, please activate
the battery with a charge/discharge current greater than 1A and measure the terminal voltage
to validate. Prior to long periods of storage, please disconnect the battery from the system. The
battery will enter shelf mode automatically after 24 hours. In shelf mode, the battery has a low
self-discharge rate and can hold the charge for a longer period of time.
●Parallel connected batteries can be activated simultaneously with a charge/discharge cur-
rent greater than 1A for each battery.
Charging Battery
●DO NOT exceed the maximum continuous charge current of the battery.
●Only charge the battery with a battery charger or charge controller that is compatible with
the lithium iron phosphate battery.
●Depending on the length of time between manufacturing and shipping, the battery may be
received at a partial state of charge (SOC). Please fully charge the battery prior to the initial
use.
During the standard charging process, the battery is rst charged at a constant current of 30A

10
until the battery voltage reaches 14.4V. Then, the battery is charged at a constant voltage of
14.4V while tapering the charge current. The standard charging process is considered com-
plete when the charge current is less than 5A. However, leaving the battery on oat will con-
tinue to balance the battery cells and will not damage the battery. The standard charging pro-
cess normally takes 3.5 hours. Safe charging requires battery temperatures between 32°F and
131°F (0°C and 55°C).
Discharging Battery
●DO NOT exceed the maximum continuous discharge current of the battery.
●DO NOT connect large loads to the battery when it is running low
●If the battery shuts o due to low state of charge (SoC), please disconnect the battery from
loads and charge the battery as soon as possible. Failure to do so may cause irreversible
damage to the battery.
●It is recommended to pair the battery with discharge equipment featuring low voltage dis-
connect.
During the standard discharging process, the battery is discharged at a constant current of 30A
until the battery voltage reaches 10V. Safe discharging requires battery temperatures between
-4°F and 140°F (-20°C and 60°C).
Battery Maintenance
Inspection
Please perform regular inspections following the steps below:
●Examine the external appearance of the battery. The top of the battery and terminals should
be clean, dry, and free of corrosion.
●Check battery cables and connections. Replace any damaged cables and tighten any loose
connections.
●Terminal corrosion may adversely aect the battery performance and present a safety haz-
ard. Please keep terminals free of corrosion.
Cleaning
Please clean the battery at regular intervals following the steps below:
●Disconnect the battery from the charging source and/or loads.

11

●The warning status can only be monitored on the DC Home app.
●The warning status will not aect the normal operation of the battery. But it is recommended
to pay closer attention to the battery to avoid triggering protections.
Battery Cell Balancing
The battery employs bypass circuit to maintain the balance between each battery cell group.
Each battery cell group is connected with a bypass resistor and a switch in parallel. During the
charging process, if the highest-voltage battery cell group reaches the set balancing starting
voltage and the voltage dierence between the highest-voltage and the lowest-voltage battery
cell group exceeds the set voltage dierence, the switch connected to the highest-voltage

14
battery cell group will be closed to shunt the charge current around the highest-voltage battery
cell group through the bypass resistor until the voltage dierence drops below the set value. To
avoid excessive energy loss, the battery cell balancing is only performed during the charging
process.
Troubleshooting
If any problems occur during the battery operation, please refer to the following instructions or
contact us for assistance:
●If the battery is unable to be activated with a charge/discharge current greater than 1A or the
battery is activated with a resting voltage below 10V, the battery may have been severely
overdischarged due to self-discharge or parasitic loads. Please revive the battery with a
battery charger or charge controller featuring lithium battery activation or force charging.
●If the battery voltage is 0V, the internal fuses may have blown due to severe over-current.
Please contact us for assistance.
●If the battery shuts o due to undervoltage protection, please disconnect the battery from
loads and charge the battery with a current greater than 1A as soon as possible.
●If the battery cuts o the charge current due to overvoltage protection, please disconnect the
battery from the charging source and discharge the battery with a current greater than 1A as
soon as possible. If the problem persists with a lithium iron phosphate compatible charging
source and the correct voltage setting, please rst reduce the charge voltage by 0.2V~0.4V
to balance the battery cells for 6 hours before attempting to fully charge the battery again.
●If the battery temperature gets too high/low during the operation and triggers the high/low
temperature protection, please disconnect the battery from the charging source and/or loads
and cool down/warm up the battery. The battery will automatically recover from the high/low
temperature protection and continue operating.
●If too high a current passes through the battery and triggers the charge/discharge over-current
protection, please disconnect the battery from the charging source/loads as soon as possible.
The battery will automatically recover from the charge/discharge over-current protection after
1 minute. If the charge/discharge over-current protection is triggered 3 times in a row, the bat-
tery will no longer recover automatically. Please discharge/charge the battery with a current
greater than 1A to recover the battery from the charge/discharge over-current protection.
●If the battery is shorted and triggers the short circuit protection, please remove the short cir-
cuit as soon as possible and charge the battery with a current greater than 1A. The battery
will automatically recover from the short circuit protection.
