11. Handling Instruction Guide for Li-ion Battery Pack
11.1 General
Battery packs supplied by Anhui GP New Energy have to be handle carefully according to the
specification. Here are some more to be followed:
11.2 Storage of pack
The packs are requested to be stored under the following conditions:
A. Indoor storage in a cool circumstances without direct sun light on the packs or cartons.
B. Store batteries in a dry location with low humidity, and a temperature range of - 20°C to +30°C. In
case of the long term storage.
C. As long-term storage can accelerate battery self-discharge and lead to the deactivation of the
batteries. To minimize the deactivation effect, store battery packs in a temperature range of +10°C to +30°C.
D. When charging for the first time after long-term storage, deactivation of the packs may have led to
decreased capacity. Recover such packs to original performance through repeating several cycles of full
charging and discharging.
E. When store packs for more than 6 month, charge at least once charring require per 6 months to
prevent leakage and deterioration in performance due to self-discharging.
11.3 Charging pack
A. Use suitable charger with the specified voltage and current. We strongly recommend smart battery
charger. We can recommend the usage or specification of the charger manufacturing. If you want to get
the information about it, please contact us.
B. Never attempt reverse charging. Charring with polarity reversed can cause a reversal in battery
polarity, causing gas pressure inside of the battery to rise, which can be lead to leakage of the batteries in
the pack.
C. Avoid overcharging. Repeated overcharging can be lead to deterioration in pack performance. And
Over-heat occurred.
D. Charging efficiency drops at temperatures above 40°C.
11.4 Protection from unexpected damaged to pack

12. Product maintenance
12.1 Routine maintenance
12.1.1 The charging operation should be supervised by professional personnel. During the charging
process, the plug and socket should be in good contact, the charging equipment should work normally,
and the connection points of the battery pack should be in good contact. If it is abnormal, it needs to be
repaired before charging;
12.1.2 If there are a lot of dust, metal scraps or other sundries on the upper cover and pole of the battery
pack, use compressed air to clean it in time, and avoid using water or water soaked objects to clean it;
12.1.3 When charging and discharging, try to avoid water or other conductive objects splashing on the
battery cover and pole, such as exposure to heavy rain;
12.1.4 The charging time and discharging time of the battery are estimated according to the actual use
state of the battery or battery pack. At the end of charging and discharging, pay attention to observe
whether the battery or battery pack is abnormal, such as the voltage difference of the battery.
12.2 Regular maintenance
12.2.1 Check whether the conductive belt, voltage acquisition terminal and other nodes are loose, falling
off, rusty or deformed to ensure that the series parallel wiring harness used by the battery pack is firm
and reliable (once a month);
12.2.2 Check the battery shell for cracks, deformation, pole looseness, bulge and other abnormalities
(once a month);
12.2.3 Check the reliability of charging equipment to ensure that the battery will not be overcharged
(once a month);
12.2.4、In case of inconsistency of charged quantity of battery pack, after consulting the manufacturer
and under the permission and guidance of the manufacturer, the following solutions can be adopted:
AIt is better to use a management system with equalization function and good equalization effect,
preferably a management system with equalization charging function.
BCharge all single batteries to 3.65v with a charging current less than 0.3C.

安徽江普新能源科技有限公司
Anhui GP New Energy Co., Ltd.
Model: 48V200Ah Page 17 of 17
Method 1: first, the whole battery is charged by series charger until the upper limit voltage protection of
single battery appears, and then all single batteries are charged by constant current charger (equalizing
charging equipment) with limited voltage of 3.65v until the voltage of all single batteries reaches 3.65v.
The performance index of the equalization charging equipment is that the input voltage can be set
according to the local AC voltage, such as AC220 V, the output voltage is dc3.65 V, and the output
current is 0.01 C, such as 10 A or 20 a. (once / 3 months or when the charged quantity is inconsistent)
Method 2: remove all the batteries in the battery pack, and use the charging and discharging test cabinet
to fully charge all the batteries, so that their charge is consistent. (once / 3 months or when the charged
quantity is inconsistent)
CThe voltage of all single cells was put to 2.3V with a discharge current less than 0.3C.
Method 1: remove all the batteries in the battery pack, and put all the batteries into 2.3V with the charge
and discharge test cabinet, so that their charge is consistent. (once / 3 months or when the charged
quantity is inconsistent)
Method 2: first, discharge the whole set of batteries until under voltage protection of single battery
appears. Then, the battery is discharged by the discharge equipment with limited voltage of 2.8V until the
voltage of all cells is equal to 2.8V. For the discharge equipment with limited voltage of 2.8V, the
discharge resistance can be controlled by voltage comparator and discharge relay. The discharge power
device is a resistance wire with a diameter of 5mm and a length of 50cm, and the current is about 20
amperes (suitable for the battery pack which can be easily disassembled). Or use 1 ohm 15W resistor,
the discharge current is about 3 amperes, it is suitable for the battery pack that is not convenient to
disassemble, it can be discharged for a long time with small current through the voltage acquisition line of
the management system). (once / 3 months or when the charged quantity is inconsistent)
13. Other chemical reactions
Because the battery is based on the principle of chemical reaction, the performance of the battery will
decrease with the increase of time, even if it is stored for a long time without use. If the use conditions
such as charging, discharging and ambient temperature are not within the specified range, the service
life of the battery will be shortened, or the leakage will cause equipment damage. If there is a big
difference between the normal discharge time and the fully charged battery, even if the charging method
is correct, it means that the battery needs to be replaced.
