substantial damage, harm, fire, or injury.
o An example of an arc flash event could be a direct short circuit caused by a metallic object such as a tool bridging
between the positive and negative of an energized circuit.
o Table 3 below quantifies the hazard level of arc flash energy that each battery system is capable of producing.
Per NFPA 70E D.5.1 "Maximum Power Method"

8 GT and GTX Series Installation Manual
2. System Installation
2.1 Short Circuit Protection
• The battery system must be protected by a DC fuse. The models listed in this document were evaluated and tested
by Underwriter Laboratories with external fuses as noted. UL Listed Class J or Class T Fuse, rated 350A (450A for GTX
Series). The fuse is to be provided downstream of the BMS before the load or supply in all cases. The fuse should be
used with a UL Listed fuse holder. The use of any other fuse or non-fuse voids the UL Listing of the models.
• Examples of approved:
o Fuse: Littelfuse JLLN-350 or Eaton DFJ-300
o Fuse holder: Littelfuse LFT30400 or Eaton JM60400-1CR-1
o Fuse placement must be directly after the positive power terminal on the BMS. (Fuse placement may be controlled
by other industry standards such as ABYC or RVIA.)
2.2 Disconnect Device Protection (only applies to GT51V150A and GTX51V315A systems)
• Per UL1973 Revision 2 Section 7.8.1.4, the GT51V150A and GTX51V315A systems must have 2 additional disconnect
devices, one located on the positive pole and one on the negative pole.
o The disconnect devices shall not require the use of special tools or equipment to be operated.
o Recommended disconnect device: Gigavac HBD41 Hermetic Battery Disconnect.
o Please see Figure 1 for the disconnect devices placement.
2.3 Battery Module and NeverDie BMS Unit Environment and Mounting orientation
• The Battery Module and BMS Unit should be mounted in an environment that does not receive direct sunlight,
pressurized water or road debris.
• To avoid power interruption, your installation may need to consider controlling the ambient operating temperature.
• Mount the Battery Module in an upright position, i.e. black lid faces up.
o Other orientations are NOT permitted and will void the warranty.
• The BMS Unit can be mounted in any orientation as long as all its features are accessible.
• Ensure that the BMS Unit is located in close proximity to the Battery Module so that all connectors can be mated in
the following steps.
2.4 Temperature Sensor Connector
• The temperature sensor cable and connector exiting the battery module must be connected to the BMS.
• Connect the two M8 circular connectors together by first aligning their pins and pressing them together, then rotate
the securing nuts until they stop snugly.
• Do not use the temperature probe from the inverter-charger manufacturer.
2.5 Main Power Connector
• The battery module has a large black female main power connector that must be inserted into the BMS’ male main
power connector. This is the connector with the large 4/0 red and black wires and single small gauge gray cable.
• Align the connectors and insert them together.
• Use 2 zip ties to bind the connectors together so that they may not separate during use.
2.6 NeverDie BMS Unit Power Terminals
• Connect the BMS Unit Power Terminals to your DC bus, both Positive (Red) and negative (Black).
o Use correctly sized wire conductors for the application.
o Torque to 80 INCH pounds
o Never stack ring terminals.
o Never place the stainless-steel washer between the Power Terminal and ring terminal lug (see Figure 1 on Page 7).
2.7 Pressure Vent
• It is recommended to install a ventilation hose onto the pressure vent barb when the Battery Module is in a location
with poor ventilation.
o The hose shall direct the gases to the atmosphere.
9 GT and GTX Series Installation Manual
2.8 BMS Unit I/O Connector
• Some systems have a rectangular I/O connector to extend the BMS Unit features remotely such as remote
Power/Reset switch, LED indicator, or serial datalogging. Be sure to connect the I/O connector if so equipped.
2.9 Initial Charge Cycle
• Initially the system must be FULLY charged once to calibrate the BMS Unit to the Battery Module. Please read and
follow the next section to perform this.
10 GT and GTX Series Installation Manual
3. System Operation
3.1 Powering the System On
• Short-press the Power switch for 1 second.
o The switch will illuminate once power is enabled.
o You may notice an audible “thunk” noise of the internal contactor switching on.
o Check that there is voltage at the Power Terminals with a voltmeter.
3.2 Powering the System Off
• Long-press the Power switch for 3 seconds.
o The switch will cease to illuminate once power is disabled.
o You may notice an audible “thunk” noise of the internal contactor switching off.
o Check that there is 0V at the output terminals with a voltmeter.
3.3 Charging
• The charging device(s) connected to the Lithium Battery System must be programmed as per Table 1.
• Charging may be performed at any time the system is powered On.
o NOTE – The Lithium Battery System will disconnect power if the voltage, amperage, or temperature limits are
exceeded during charging.
o Only use a Lithionics Battery approved charging source. Please contact Lithionics Battery for charger approval.
3.4 Initial Charging Cycle
• The initial charging cycle is required as it calibrates the NeverDie BMS to the Battery Module for accurate State of
Charge percentage (SoC) monitoring.
• During the initial charging cycle, the system must reach a voltage level that is equal to the Standard Full Charging
Voltage indicated in Table 1.
• Enable the charging device(s) so that they may complete a charge cycle. It is recommended to not have any discharge
loads active during the initial charging cycle, especially towards the end of charging.
3.5 Discharging
• Discharging may be performed at any time the system is powered On.
o NOTE - The Lithium Battery System will disconnect power if the voltage, amperage, or temperature limits are
exceeded during discharging.
• The NeverDie feature allows the system to have a “reserve” amount of energy left in the battery. Once the system is
discharged to 12.0V or 10% State of Charge (SoC), whichever comes first, power will be disabled to leave a “reserve”
amount of energy still left in the battery.
• To enable the remaining reserve energy of the system, short-press the Power switch for 1 second.
o NOTE - Once the reserve range is enabled the battery should be charged as soon as possible.
o WARNING - If the reserve energy is used and the battery module is left in a deeply discharged state without
immediate charging, the battery module will become permanently damaged.
11 GT and GTX Series Installation Manual
3.6 System Storage Procedure
• Storing your battery at the correct specifications is important as it keeps the battery in the healthiest state possible
for the fastest deployment when needed.
• If the Lithium Battery System will not be in use for greater than 2 weeks, it is recommended to enable system storage.
• Storage mode is simply a fully charged system in the Powered Off state.
• To enable System Storage:
o Perform a full charge cycle, ensure that the System voltage reaches the Standard Full Charging Voltage indicated in
Table 1.
o Power off the System, long-press the Power switch for 3 seconds. Check that the switch is no longer illuminated.
Check that there is 0V at the Power Terminals with a voltmeter.
