Overview
The purpose of this Owner’s Guide is to provide explanations and procedures for operating, maintaining, and troubleshooting the
GTX12V315A-E2107-CS200 battery. The GTX12V315A battery is a lithium iron phosphate (LiFePO4) chemistry battery with an internal
NeverDie® Compact Series 200 Battery Management System (BMS). The BMS monitors voltage, current and temperature of each cell
inside the battery and protects the battery from potential damage by disconnecting the battery circuit when the monitored
parameters go outside of the allowed limits. The BMS also transmits monitoring data over Bluetooth which allows customers to check
the battery data on their mobile device.

First Power-up
The battery needs to be fully charged to 14.4V to condition the battery for use. Fully charging the battery calibrates the state-of-charge
percentage to be the most accurate and allows the cells to balance if necessary. The battery should be fully charged to 14.4V at least
once every 2 weeks.
Operation
Before powering on, ensure the battery terminals are insulated and any connected devices are properly fused.
Due to shipping laws and regulations, your battery may be received at a partial state-of-charge (typically 50%). The battery needs to
be fully charged before use. This is necessary to calibrate the state-of-charge meter.
Powering the Battery On The power button is located on the battery lid and/or on the remote accessory harness extension. To turn
the battery on, press the power button for one second. The power button status light will illuminate solid on to confirm the battery is
powered on and operating normally.
Powering the Battery Off Be sure to shut down any high amperage loads prior to turning the battery off. To turn the battery off,
press and hold the power button for 3 seconds. The power button status light will turn off to confirm that battery power is off.
Resetting Power after a Protection Event If the battery detects a fault then it may turn power off. The battery can then be reset by
pressing the power button for one second.
Discharging Discharging may be performed at any time the system is powered On. The NeverDie® feature allows the system to
have a “reserve” amount of energy left in the battery. Once the system is discharged to approximately 12.0V or 10% state-of-charge,
whichever comes first, power will be off to leave a “reserve” amount of energy still left in the battery. The battery will also disconnect
power if the voltage, amperage, or temperature limits are exceeded during discharging. To enable the remaining reserve energy of
the system, press the BMS power button for 1 second. Once the reserve range is enabled the battery should be charged as soon as
possible. See page 9 BMS Functions for further details.
WARNING - If the reserve energy is used and the battery module is left in a deeply discharged state without immediate charging, the
battery module may become permanently damaged.
Charging The charging device(s) connected to the Lithium Battery System must be programmed per the recommended charge
settings below. Using an improper charger or charge settings could result in undesirable battery performance and accelerated wear.
The battery will disconnect power if the voltage, amperage, or temperature limits are exceeded during charging. Please note that
voltage rise during bulk charge stage is very slow, followed by a fast voltage rise at the end of charge. Once charge is completed, the
voltage drops down to a resting level. This behavior is normal and should not cause any concerns.
A lithium iron phosphate (described as LFP or LiFePO4) charger or
charging profile is required for battery charging. The battery
charge voltage should be set to 14.4V, equalization and
temperature compensation must be disabled, and if the charger
supports float mode, set it to 13.4 - 13.6V. If you are not sure if
your charger is suitable for charging your battery, contact
Lithionics Battery® or your dealer to confirm charger
compatibility, or to purchase compatible charger.
NOTE - Due to partial state-of-charge during storage and shipping, the cells inside the battery may not be perfectly balanced during
the first few charge cycles. You may observe some high voltage alerts and cell balancing status codes on the Lithionics Battery® Monitor
app, which indicate the balancing process is in progress. This is perfectly normal behavior and should not cause any concerns. After a
few full charge cycles the cells will balance out and these alerts will disappear. There is no adverse effect on battery operation, you
may continue to use the battery normally during these initial charge cycles.

BMS Functions
Below is a detailed description of advanced BMS features and how they affect the state of the battery. Some features depend on setup
parameters which are described in detail in the Configuration section of this user guide.
▪Power On/Off –In addition to the automatic disconnect protections, the battery can be manually turned off to disconnect
power at the terminals during installation, service, or storage.
▪Reserve Voltage Cutoff (RVC) –During discharge, the BMS will disable discharge current at approximately 10% state-
of-charge, or when any cell reaches 3.0V (approximately 12.0V total voltage). This allows the battery to store a small energy
reserve. Once the battery is in the RVC state you can use the reserve energy by a short-press of the power button.
oIt is recommended to charge the battery soon once it reaches RVC.
oThe battery will fully power off if it is not charged after sitting for 72 hours to further conserve its energy.
▪Low Voltage Cutoff (LVC) –During discharge, the BMS will disable discharge current when any cell reaches the 2.6V
(approximately 10.4V total voltage). Charging current is allowed, so that the battery can still be charged by a charging source.
Some charging sources require to “see” the battery voltage before allowing charging, in which case LVC lockout can be
temporarily overridden by short-pressing the Power button. This will allow the charger to sense the battery voltage, so
charging can begin.
oIt is recommended to charge the battery immediately once it reaches LVC.
oThe battery will fully power off if it is not charged after sitting 12 hours to further conserve its energy.
▪High Voltage Cutoff (HVC) –During charging, the BMS will disable charge current if any cell reaches 3.75V or higher
(approximately 14.8V total voltage). This should not happen during normal operation if the charging sources are setup with
correct charge settings. Once the charge current is removed the battery voltage will slowly lower and the BMS will
automatically disengage HVC.
▪Cell Temperature Based Cutoff –When the internal battery temperature goes below or above the temperature limits
the BMS will disable charge or discharge current to prevent further use of the battery until the temperature returns to safe
operating limits. Different temperature limits are enforced for charging and discharging due to the nature of LiFePO4
chemistry. Please see the specifications table below for temperature limits.
▪BMS Temperature Based Cutoff –When the BMS temperature goes above 180F the BMS will disable charge and
discharge current to prevent further use of the battery until the temperature lowers to below 160F.
▪Over Current Protection –The BMS will disable discharge or charge current if the amperage exceeds 300A for 2 minutes
continuously. To restore normal operation, remove/address the source of the overload, then short-press the Power Button.
▪Short Circuit Protection –The BMS will immediately disable discharge current if the current value exceeds 1200A. To
restore normal operation, remove/address the source of the short circuit, then short-press the Power Button.
NOTE - The lithium battery is capable of significant power output and may maintain the voltage level during a short circuit
event, producing a very large current capable of melting or welding connection points and damaging cables and connectors.
Even when the BMS detects the short circuit and tries to protect, the BMS may be damaged under such a large current. Make
sure that the battery connection is always properly fused and does not rely on the BMS alone for short circuit protection!
▪Internal Heater Kit –The internal heater kit will warm the battery when the cell temperature is 35F and lower and will
stop heating when the cell temperature is 40F and higher.

Troubleshooting & FAQ
When troubleshooting your battery, one of the most helpful tools is the battery Status Code feature of the Lithionics Battery Monitor
App. If the battery shuts down due to a protective BMS feature, please have the Bluetooth app available when resetting the battery
to identify the battery info and status code. It can be helpful to screenshot the battery info screen, which will identify the battery
state-of-charge, voltage, current, temperature, and status code. The following status code descriptions can be used in correcting the
battery fault condition.
Frequently Asked Questions
1. The battery has been charging for a long time, why has it not reached 100%?
Depending on the charger output, charging could take several hours to complete. To confirm the battery is charging, check
the Bluetooth app to verify positive current is going into the battery. The voltage rise during bulk charge stage is very slow,
followed by a fast voltage rise at the end of charge to 14.4V. Once the battery reaches 14.4V, the State-of-Charge percentage
will calibrate to 100%. If no current is measured, confirm the charger is powered on, programmed correctly, and there are no
DC breakers or disconnect switches preventing power from transferring.
2. The battery is at 100%, why is it still charging?
It is normal for the charger to finish the charging cycle for a short period of time after the State-of-Charge percentage
calibrates to 100%. A 30-60 minute absorb cycle is recommended as the battery finishes charging and the charging current
reduced. The charger should then switch to a float charging mode at the battery resting voltage.
3. I have lost battery power, why did the battery turn off?
The battery has many automatic protections that could cause the battery to turn off. Most commonly, the battery will turn
off once you reach the 10% reserve range and just needs to be recharged. Using the Bluetooth app and Status Code can
provide you with helpful information for troubleshooting.
4. Why is the battery status light flashing?
The LED flash pattern can indicate if the battery is being charged, in a low voltage state, or experiencing a fault condition.
Reference the chart on page 5 for the status light pattern descriptions.
