Introduction
Neuton Power 12.8V LiFePO4 (LFP) Slimline (SL) series are ultra-thin LiFePO4 solutions, which are specially
designed for UTE, 4WD and marine applications. Constructed with high-quality prismatic cells, these
batteries were made for better consistency and reliability.
The BMS built into the battery system gives it added protection, which is responsible for collecting and
analyzing the voltage, temperature and current of each cell. It provides cell balancing and protection
against over-voltage, under-voltage, high and low temperature, and short circuit.

Features
The NPL (SL) battery includes some of the following features:
•Battery Management System (BMS) for protection and safety
•High acquisition of voltage data collection (5mv).
•Intelligent cell balancing.
•Over charging, over discharging, over temperature, short circuit protection.

Installation Guide
Preparation
Before installation, please read through all safety information provided in this document. If you have any
questions about operation and safe use of the battery system, please contact technical support.
Before Operation:
•Work must be carried out by qualified personnel who have completed the required training and are
certified to undertake electrical work in their state.
•Remove all metal items, such as jewelry, watch, pen etc. from body.
•To ensure the safety of construction personnel and equipment, disconnect the battery pack from
the operating equipment during wiring.
•Follow the connection port description and system connection diagram. Pay attention to the
terminal polarity of the battery module.
•Ensure the tools insulation are in proper condition and to use them correctly.
•Do NOT plug or unplug the battery when it is in operation. Necessary work should be conducted
after the power supply is disconnected.
•Before its formal operation, ensure whether the power terminals are properly connected and
tightened. When it is necessary to take measurements, be careful to use the instruments and tools
to avoid short circuit and other accidents.
•Do NOT disassemble the battery without the proper authorisation from manufacturer
Compatibilities
Do NOT connect different batches, different types, old and new batteries in one bank. To connect the
batteries into a bank (in series and/or in parallel), the batteries should meet the following conditions:
•All batteries must be from the same brand and same model.
•Have the same battery capacity (Ah).
•Are of similar age, preferably manufactured from the same batch.

Charging Batteries before Use
Before connecting the batteries in a matrix, the following steps are necessary to reduce the voltage
difference between batteries and thereby optimising its performance.
1. Fully charge your batteries separately.
2. Disconnect the batteries, then let them rest for approximately 12-24 hours.
3. Connect your batteries in series, and then you can connect your battery strings in parallel.

Pg. 7
NPL (SL) Battery Terminal
NPL (SL) series have two terminals for Anderson 175A blue plugs (as shown below).
Note: Anderson cables not included with the purchase of the battery
Only use the same plug model type together (Blue Anderson 175A).
The Anderson plugs will only insert in one orientation. If the orientation is wrong, it will not connect.

Storage, Safety and Limitations
•Charging current must be less than the maximum charging current specified in the data
sheet.
•Charging current exceeding the recommended current may damage the battery.
•The discharge current must be less than the maximum discharge current specified in the data
sheet.
•Discharge current bigger than the recommended current may damage the battery.
•Non-qualified personnel are not allowed to disassemble the battery.
•Do NOT reverse charge the battery.
•Battery pack should not be used or placed in high temperature. Do NOT use or store under direct
sunlight. It may cause overheat, function failure and shorter life.
•Battery pack should be placed in dry and cool environment when not in use.
•Do NOT immerse into water.
•Do NOT install or disassemble the battery pack when it is live.
•For optimum performance, you must charge at 14.6V. If you do not, you will not be able to
reach the full usable capacity of the battery.
•To ensure the best performance of the battery when stored for a long time, the battery should
be charged and discharged every 3 months.
Disengaging the Protection
To disengage the BMS protection, follow the following steps:
1) Disconnect the battery from the load and allow it to rest for 15-20min. If the problem persists, go
to the next step.
2) Use a constant voltage (CV) charger to charge the battery for 5min ONLY. Constantly monitor its
voltage until it reaches the recovery voltage of 11.2V, then disconnect the CV charger. Do NOT let
it charge unsupervised.
Alternatively, you can use another 12V lithium battery with the same capacity to connect in
parallel with the battery and let them piggyback each other for approximately 12hours.
3) To fully charge the battery, use a LiFePO4 charger.

Controller Settings
When charged with controller, and the controller output is used to connect load:
It is recommended that the controller is set to the following parameters to avoid failure of the battery
to recover when the BMS cut off the battery for protection after a continuous small current
discharge.
Max charge voltage: 14.6V
Overcharge protection voltage: 14.8V
Overcharge recovery voltage: 14.2V
Discharge cut-off voltage: 11.2V
Over-discharge recovery voltage: 11.6V
The above settings ensure that the controller triggers its protection before the BMS does, thereby
prolonging the service life of the battery.
If solar charging is used, please set the regulator to LiFePO4 charging mode.
LCD Screen
1. Press the function key once and the screen will light up to display the battery voltage.
2. Press the function button again to display the State of Charge (SOC).
3. On the third press, the display screen will turn off.
