2.2.2 Battery pack interface functions
2.2.2.1 The positive and negative terminal blocks
The red terminal block is the positive pole of the battery, and the black terminal block is the negative
pole of the battery. It is locked with M6 screws. When installing, the SC25-6 copper nose can be used
for parallel connection of battery packs or external equipment for energy supply or charging.
2.2.2.2 LCD display and control
LCD display and control are divided into display part and control part.
(1) The control part is button control, as shown in the figure below, from top to bottom are POWER,
UP, DOWN.
Power on:
①Long press the POWER switch until the red light turns on (first the
green light turns on, but the switch shouldn’t be released).
②The system self-checks when the red light is flashing (about 10S). After
that, the battery will enter the power-on state.
Power off:
①Long press the switch (about 6S).
②The green light goes out briefly and then flashes to enter the self-test
(about 10S). After that, the battery will be completely power-off.

Solution
The battery is undervoltage, it is recommended to
charge it as soon as possible.
Check whether the charging current of the charging
device is too large.
1. Check whether the charging current of the
charging device is too large;
2. Use a current clamp to test whether the battery
input current is consistent with the displayed current.
If the difference is large, the BMS current may be
inaccurate and needs to be replaced by a professional
or authorized person.
Check whether the load of the battery is too heavy,
and appropriately reduce the load.
1. Check whether the load of the battery is too
heavy, and appropriately reduce the load;
2. Use a current clamp to test whether the battery
output current is consistent with the displayed
current. If the difference is large, the BMS current
may be inaccurate and needs to be replaced by a
professional or authorized person.
1. Check whether the battery output is short-circuit-
ed;
2. Check whether the battery output load is seriously
overloaded;
3. If E83 is still displayed after eliminating the above
conditions, restart the BMS.
Check whether the voltage of a certain cell exceeds
3.8V on the display screen, but the other voltages are
normal and basically the same. It is possible that the
battery cell is faulty and needs to be repaired.
The battery is undervoltage, it is recommended to
charge it as soon as possible.
The battery is supplied with undervoltage. Charge it
as soon as possible, otherwise the battery may be
damaged.
It is recommended to appropriately reduce the charge
and discharge current.
1. At this time, the BMS has automatically cut off the
charging and discharging current, and automatically
resumes charging and discharging when the
temperature drops, appropriately reducing the
charging and discharging current to avoid over-tem-
perature protection;

4.2 Daily maintenance of battery pack
1. Check the voltage data on the BMS display and the actual battery voltage value to ensure the accu-
racy of the voltage collection of the BMS. If they are inconsistent, proofreading is required. The error
between the collected voltage and the actual battery voltage does not exceed 10mV.
2. Check the temperature collection data and actual temperature value of the BMS, and the data error
between the collected data and the actual temperature value is not allowed to exceed 3°C, to ensure
that the battery will not be charged or discharged when the temperature is too high or too low.
3. Check the BMS current collected data and actual current value, the error is not allowed to exceed
1%, to ensure that the battery will not be charged or discharged by overcurrent.
4. Check the reliability of the charging equipment to ensure that the charging equipment performs
charging according to the voltage and current regulationsent by the BMS, to ensure that the battery
will not be overcharged.
5. Check the connection of the battery pack is good, the contact points are in normal contact, and
there is no accumulation of dust, powder, metal chips.
4.3 Caution
1. Children are not allowed to use the batteries.
2. It is forbidden to disassemble the battery.
3. Keep batteries or battery packs away from dangerous items or materials, such as corrosive chemi-
cals, dangerous machinery and equipment, and high-temperature environments.

2. If E112 is displayed without charging or discharg-
ing, please restart the BMS once. If the problem
persists, it means that the BMS is damaged and
needs to be replaced by a professional or authorized
person.
It is recommended to charge and discharge in a high
temperature environment.
1. It is recommended to charge and discharge under
a higher temperature environment;
2. If the current ambient temperature is between
-20°C and 55°C but E122 is displayed, please restart
the BMS once. If the problem persists, please check
whether the internal plug is loose;
3. If the internal wiring harness plug is not loose, it
means that the BMS is damaged and needs to be
replaced by a professional or authorized person.

4. Unreasonable use of this of products may cause smoke, such as external short circuit, overcharging,
and high ambient temperature. If smoke occurs, please cut off the power in time, use carbon dioxide
or dry powder fire extinguisher for treatment, and bury it with sand or mud. The crowd must be evac-
uated in time during the entire process.
5. Unreasonable use of this series of products may cause the single battery to swell. In severe cases,
it may cause the casing to rupture or crack. In these conditions, the battery should be stopped imme-
diately. Please contact our technical department or after-sales service department for further solution.
6. It is forbidden to short circuit the positive and negative terminal of the battery directly, and avoid
any metal or other conductive objects contacting the positive and negative terminal of the battery.
This operation may cause personal injury or property damage.
7. It is forbidden to immerse the battery in water or other conductive liquids. This operation may
cause personal injury or property damage.
8. It is forbidden to use this product in series or parallel with other types of batteries. It is also forbid-
den to connect the whole system in series or parallel operation with other batteries. These operations
may cause personal injury or property lose. If necessary, please contact the relevant technical depart-
ment to obtain the correct technical support.
9. It is forbidden to get wet under the environment of more than 95%RH, even immerse in water.
Otherwise, it may cause internal short circuit, loss of function or abnormal chemical reaction, and
cause fire, smoke, explosion and other accidents.
10. It is forbidden to put the battery system into fire or to be exposed to a high temperature environ-
ment exceeding the temperature conditions specified in this specification for a long time. These envi-
ronments above the safe temperature range will cause a significant decrease in the performance and
life of this product, and even cause serious consequences such as combustion and explosion.
11. It is forbidden to store and use in an environment with high static electricity or high electromag-
netic radiation. Otherwise, the electronic devices in this product will be damaged, which may cause
potential safety hazards.
12. Connect the positive and negative terminal of the battery system strictly in accordance with the
instructions, and reverse charging is prohibited.
13. When the electrolyte leaks, avoid contacting the electrolyte with skin and eyes. In case of contact,
wash the area with plenty of water and seek medical assistance. It is forbidden for any person or
animal to swallow any part of the battery system or the substance contained in the battery system.
14. Protect the battery system as much as possible to avoid mechanical vibration, collision and pres-
sure shock, otherwise the battery system may short circuit, resulting in high temperature and fire.
