3 BATTERY OPERATION
The Essential Lithium-Ion GC2 batteries are
equiped with an integrated button and LEDs to
assist with turning battery on/off, SOC deter-
mination, fault/error handling, and status ref-
erence. Below is a description of the various
button and LED functions.
3.1 TURNING ON
To turn on battery, press and hold the button for 5 seconds. LEDs should light up indi-
cating the SOC of the battery. Voltage should be present at the terminals and the But-
ton LED should ash green every 5 seconds. Note that if multiple batteries are con-
nected in parallel, turn-ing on one battery will turn on all batteries in a string
3.2 TURNING OFF
To turn off, tap once and then tap and hold the button for at least 6 seconds. LEDs 2
and 4 should light up indicating you can release the button to power off. Voltage should
no longer be present at the terminals and the Button LED should no longer be ashing.
Note that if multiple batteries are connected in parallel, with CAN cables installed, turn-
ing off one battery will turn off all batteries.
3.3 ACTIVE MODE AND SOC DISPLAY
When the battery is on and there are no faults/errors, the battery is in “Active” mode.
This mode is identied by the green Button LED ashing every 5 seconds. In this
mode, the battery is ready to be used and voltage is present at the terminals. While in
this mode, you can tap the button once to reveal state of charge as indicated in
“Table 2”. Note that this will display for 5 seconds:

3.5 FAULT TROUBLESHOOTING
UNDER VOLTAGE
Battery has been overdischarged. The batteries need to be charged immediately. If
the batteries are in a motive application, wait approximately 15 minutes to allow the
voltage to increase. If the fault is no longer active, turn on the vehicle and drive imme-
diately to the charging station. Fully recharge the battery pack.
OVER CHARGE CURRENT
Charge current is greater than the maximum allowed. Verify charger is designed for
Lithium Ion and that the algorithm is also set for Lithium Ion.
OVER DISCHARGE CURRENT OVER DISCHARGE CURRENT
Discharge load is greater than the maximum allowed. Verify that the battery pack is
sufciently sized for the application. Installing an additional battery in parallel may be
required in order to decrease the discharge load across each battery below the maxi-
mum allowed.
SHORT CIRCUIT
Stop operation immediately. Short circuit protection is activated when when the dis-
charge current exceeds the short circuit limit in Table 6. This is a dangerous scenario
and should be handled with extreme caution. Verify that all connections are secure
and free of obstructions. Verify that batteries are clean of all debris. If fault occurs
again, have a professional evaluate the electrical system.

4.1 CABLE SIZE AND BOLT/NUT SPECIFICATION
Cable Size with Max Ampacity Table
Cable size has a direct inuence on the voltage drop across the system. The following
are guidelines. A trained professional should verify that your system is correctly sized
and installed. Cables must be sized according to the expected load using “Table 5”.
CHARGE OVER TEMP
Battery internal temperature has surpassed the maximum. The battery must be al-
lowed to cool. The wait time is dependent on the ambient temperature and battery
box design. Battery cables can come loose and cause a signicant rise in tempera-
ture. Check that all battery cables are secure. If multiple batteries are in parallel,
make sure that there is at least a 1 inch gap surrounding the battery.
CHARGE UNDER TEMP
Battery Internal temperature has surpassed the minimum. Battery temperature must
be allowed to increase before usage. Do not heat the battery using external devices
such as heat guns, ovens, etc. To prevent future “under Temp” errors store the
batteries or vehicle inside a temperature controlled environment.
DISCHARGE OVER TEMP
Battery internal temperature has surpassed the maximum. The battery must be al-
lowed to cool. The wait time is dependent on the ambient temperature and battery
box design. Battery cables can come loose and cause a signicant rise in tempera-
ture. Check that all battery cables are secure. If multiple batteries are in parallel,
make sure that there is at least a 1 inch gap surrounding the battery.
DISCHARGE UNDER TEMP
Battery Internal temperature has surpassed the minimum. Battery temperature must
be allowed to increase before usage. Do not heat the battery using external devices
such as heat guns, ovens, etc. To prevent future “under Temp” errors store the batter-
ies or vehicle inside a temperature controlled environment.
4 INSTALLATION

12 U.S.Battery Mfg. Co.
Table values are from NEC table 321.15(B)16
for copper cables rated at 167˚F (75˚C), op-
erating at an ambient temperature of no more
than 86˚F (30˚C). Lengths in excess of 6 feet
(1829mm) may require heavier gauge wire to
avoid unacceptable voltage drop. In series/
parallel banks, it is preferable for all series
cables to be the same length, and all parallel
cables to be the same length. Refer to the
national Electrical Code for correct wire sizing
which can be located at http://www.nfpa.org/.
4.2 TERMINAL PROTECTION AND INSTALLATION
During installation and handling, ensure that terminals are covered with supplied ter-
minal protectors and only remove when ready to attach cables. It is recommended that
cables be installed while the battery is turned off. See “3 Battery Operation” for instruc-
tions on turning batteries on/off.
4.3 BATTERY ORIENTATION
Lithium-Ion batteries can be oriented in any direction except upside down.
4.4 PARALLEL BATTERY CONNECTIONS
Lithium-Ion batteries should never be installed in series connection. Only parallel
connections are recommended. You can increase the capacity by creating a parallel
connection as shown in “Diagram 3”.
Never install multiple batteries in parallel without rst checking the SOC. The best way
to ensure batteries are matched is by fully charging each battery prior to installation in
parallel. Another way would be to ensure voltages are within 0.5V of one another prior
to installation. Always install the batteries in the “Off” state by following
“3 Battery Operation”.

4.5 ACCESSORIES
Never connect accessories directly to the batteries (except for the U.S. Battery compat-
ible remote display). 12V accessories should use a DC-DC power converter that is tied
into the key switch of the vehicle. Accessories should be installed in a way that they do
not drain the batteries while not in use. Please consult your U.S. Battery dealer when
installing accessories on vehicles using lithium-ion batteries.
4.6 BATTERY ENVIRONMENT
• Ventilation
Lithium-Ion batteries do not need ventilation during charging. In rare and adverse
scenarios, a lithium-ion battery may vent momentarily to release pressure from a cell
release. If this occurs, please discontinue use (charging or discharging) of the battery
and contact U.S. Battery technical support.
When using multiple batteries in parallel, it is extremely
important that batteries are at the same state of charge (SOC)
when installed.

• Environment
Batteries should always be installed or stored in a clean, cool, and dry place. Keep
water, oil, and dirt away from the batteries. If these materials are allowed to accumu-
late on the batteries, current leakage can occur resulting in self-discharge and possible
short-circuits. For the same reason, relative humidity should be kept below 90%.
• Temperature
The recommended operating temperature range for US Battery lithium-ion batteries is
listed in “Table 1” on page 6. Temperature plays a major role in battery usage. Hot
batteries will deliver more capacity, but with diminished cycle life. Cold batteries deliver
less capacity and are harder to charge. Temperature variations between cells can also
have a negative effect on battery capacity and life. Temperature impact on performance
is demonstrated below:

5.1 DISCHARGE SPECIFICATION
Lithium-Ion batteries have a relatively “at” discharge curve when compared to lead-ac-
id batteries. In other words, the voltage stays level for most of the discharge until the
very end. Therefore, estimating the state of charge (SOC) using voltage is unreliable.
Many electric vehicles designed for lead-acid batteries have SOC displays that rely
on voltage and as such these displays will no longer be accurate when used with lithi-
um-ion batteries. The only way to determine SOC is by viewing the LEDs on the
battery or with the U.S. Battery Remote SOC Display.

6 CHARGING
6.1 BEFORE CHARGING
Proper charging is critical to maximize battery performance and life. Both under- and
over-charging batteries can signicantly reduce the life of the battery and cause a safe-
ty hazard. For proper charging, refer to the instructions that came with your equipment.
Most chargers are automatic and pre-programmed. Some chargers allow the user to
set the voltage and current values.
6.2 CHARGING PROFILES
When charging lithium-ion batteries, it is important to select the correct charge pro-
le/setting to ensure safety and performance. Using incorrect charging proles or
methodologies can reduce performance and life and may result in battery fault
conditions. When in doubt, contact U.S. Battery.
Lithium-ion batteries most commonly are charged using a two-stage prole often called
IU or CC-CV proles. The two stages consist of a constant current (CC) charge step
(charge current is xed while voltage rises) followed by constant voltage (CV) charge
step (voltage is held constant while current falls).
Below are the charging setpoints compatible with the 24 volt and 48 volt lithium
batteries:
-Max Output Current (CC) of 0.5C of pack capacity in Amps
o For example, a 60Ah pack has a recommended current
is 30 Amps or less
-Max Voltage (CV) at 3.45 - 3.55 volts per cell
o For example, a 48V application (16 cells) should be
charged at 55.2 - 56.8 Volts. For 24V application (8
cells), voltage range of 27.6 - 28.4 Volts

6.3 CELL BALANCING
Lithium-Ion battery packs contain multiple cells in series and/or parallel arrangements.
Due to inherent variations in cell manufacturing processes, no two cells are identical.
As a result, during charging and discharging, cells become “unbalanced” meaning they
are not at equivalent states of charge. If not properly managed, this can cause prema-
ture failure of the battery pack. To address this the battery management system (BMS)
“balances” cells by discharging the cells that are at a higher state of charge. This
brings these cells in closer alignment with other cells in the pack.
For this to occur properly, it is very important proper charging procedures are followed.
Cell balancing occurs at the end of charge and as a result this is the most critical
charging period.
6.4 CHARGING FAQS
The following is a list of common questions and concerns regarding system setup,
battery charging procedures. Please refer to these as general guidelines. For further
assistance with your specic system setup, please contact your Installer.
CAN I USE MY EXISTING LEAD-ACID CHARGER?
• This answer depends on the specic charger as some chargers contain multiple
settings. If the charger can be re-programmed or the settings can be changed
to accommodate “lithium iron phosphate” cells, then yes. However, lead-acid
charging proles or settings are not compatible. Contact the charger manufacturer
or authorized U.S. Battery distributor for information on how to determine if your
charger can be re-programmed.
HOW LONG DOES A CHARGE CYCLE TAKE?
• There are several factors that impact charge time: charger output power (wattage),
number of parallel batteries in pack, and state of charge of pack when charging
starts. But as a general idea, a 20A charger can charge a 48V 60Ah battery pack-
from 0 to 100% in about 3.5 hours.

20 U.S.Battery Mfg. Co.
CAN I OPPORTUNITY CHARGE?
• Yes, this is a great feature of lithium-ion batteries. They can be charged during a
break in usage and can quickly regain capacity. A good example would be plug-
ging in for an hour while on lunch to get extra runtime. While this does not harm
the batteries, it is important that full charge cycles are completed periodically for
cell balancing as mentioned in “6.3 Cell Balancing”.
DO THE BATTERIES GAS OR NEED VENTILATION?
• Lithium-ion batteries under normal operating conditions do not “gas”. The only ven-
tilation required would be for cooling the batteries if charging in high temperature
climates.
WHAT TEMPERATURES CAN I SAFELY CHARGE AT?
• The charging temperature range of the cells is 0-55ºC (32 -131ºF)
CAN YOU “EQUALIZE” LITHIUM-ION BATTERIES?
• No, equalization charging is specic to lead-acid batteries and may result in battery
fault conditions.

For long term storage (more than a month) batteries should be stored, fully charged,
and turned off. You can turn the batteries off by following the directions in “3 Battery
operation”. This will ensure low self-discharge rate and allow storage of up to one year.
Batteries will automatically enter a “sleep” mode after 72 hours of inactivity. Once sleep
mode is entered, a button press is required to “wake” the batteries. This can be done
on the U.S. Battery Remote SOC Display.
Beware of and isolate any electronics that may consume power even with the key
switch off such as DC-DC converters, stereos, lights etc.
