Site environment requirements: Keep away from heat source, avoid direct sunlight, no corrosive

gas, no explosive gas, no insulating gas, no insulating conductive dust.

Always check all applicable local, national, and international regulations before transporting

the BLUE JOY battery.During the transportation, protected the battery from severe vibration,

shock or squeezing during transportation, as well as to prevent sun and rain. During the loading

and unloading process, the battery should be handled lightly and protected against falling,

rolling and heavy pressure.

Follow the storage instructions in this manual to optimize the lifespan of the BLUE JOY battery during

storage. If these instructions are not followed and the BLUE JOY battery has no charge remaining

when it is checked,consider it to be damaged. Do not attempt to recharge or use it. Replace it

with a new BLUE JOY battery.

According to the characteristics of the cells, it is necessary to create a suitable environment for

the transportation of lithium iron phosphate battery packs to protect the batteries. The battery

should be stored in a dry, clean and well-ventilated warehouse at -20℃-45℃.The self-discharge

( 25°C) of the BLUE JOY battery is 3% per month.

1. Store the battery in a cool and dry place without direct sunshine.

2. Keep the battery away from corrosive substances, inﬂammable and explosive material as well as

hazardous gases.

5.Installation

Only those who have been trained in the power system and have a good knowledge of the power

system are allowed to install the device.Always observe local safety regulations.

Before installing or removing the device, make sure that the power system is not powered and

that the battery device is turned oﬀ. Distribution cabling should be reasonable and with protective

measures to avoid being touched during operation.

5.1.1 Installation preparation

The operating environment should meet the requirements described in Chapter 4, “Operating

Environment”. Otherwise, it needs to be adjusted and re-examined.

5.1.2 Checking the operating environment

Fire-ﬁghting equipment such as portable dry powder ﬁre extinguishers should be available near

the equipment. Do not place dangerous materials such as ﬂammable or explosive ones near the

battery.

5.1.3 Security check:

The battery pack can only be square or wall mounted vertically. When installing the battery, be

careful not to fall or tip over. All equipment must be steady during installation.

5.3 Installation

● When the battery arrives at the installation site, it must be loaded and unloaded properly and

prevented from the direct sunshine and rain. Before installation, check if there is any component

missing according to packing list attached in the packing box and check whether the box

appearance is intact;

● Carefully handling during the unpacking. Protect the insulated coating on the case surface;

● Check the BLUE JOY battery for damage after unpacking. If there is any damage, contact your

reseller.

5.2 Unpacking

1) Four persons who lift battery out of carton, using black ribbon.

a. Put the battery on the lift or chair,desk . For setting height(from bottom),It is not less than

20cm ,and the recommended setting height is 50 cm.

b. Fix the battery to the wall with four expansion screws, then put the coulometer and switch

back the front panel of the battery, and screw down fairly tight.

c. Turn on the switch, and It shows 50volt of the coulometer, that’s good product.

Before connecting the power cable, connect and disconnect the cable to identify the positive and

negative terminal, then make a mark respectively. After the cable is connected, measure whether

there is a short line or reverse connection.

Note: When the cable is inserted into the positive and negative terminals of the battery and

“Click”, the cable is ﬁrmly connected. Before pulling out the cable, press the small button next to

the terminal. When multiple batteries are connected in parallel, in order to reduce the inﬂuence of

the circular current, the overall positive and negative output cables can be connected from

diﬀerent batteries.

5.4.Activation

Before activation, check again if all cables are properly and ﬁrmly connected, also make sure there

is no short circuit and reverse connection.

When the battery power is too low to be turned on, charge the battery by connecting the battery to

inverter.

●This product is a professional coulomb meter that based on battery status measurement. It

detects battery datas such as voltage, amperage, power, realtime capacity, remaining use time,

etc. With this product, you can check the exact working status of your battery anytime.

●Through scientiﬁc method and unique algorithm, it is able to measure the battery capacity

accurately. The calculation is done entirely by the meter itself. No need to set the meter manually.

●Two-direction current detect. Automatically identify and detect charge and discharge current, no

need to change the wiring direction.

●Complete warning alarm. The meter has multiple settable warning alarm such as over voltage

alarm, over current alarm, low voltage alarm, low capacity alarm, high temperature alarm, etc.

●Cut-oﬀ memory. Auto-memorizing the battery capacity value and percentage before the power

cuts oﬀ.

●Visualized setting menu. Easy setting voltage, amperage, temperature or reset the meter through

the LCD monitor.

When the battery voltage is lower than this value,

the capacity would be set to 0%.

When the battery voltage is higher than this value and the

voltage number ﬂashes, the beeper rings every 0.5s.

When the battery amperage is higher than this value and the

amperage number ﬂashes, the beeper rings every 0.5s.

When the battery voltage is lower than this value and the

voltage number ﬂashes, the beeper rings every 0.5s.

When the battery capacity is lower than this value and the capacity

percentage and the battery icon ﬂashes, the beeper rings every 0.5s.

When the battery temperature is higher than this value and the

(This model does not equipped with this function).

When the displayed voltage does not ﬁt the actual voltage,

it can be ﬁne-tuned within certain range.

When the displayed amperage does not ﬁt the actual amperage,

it can be ﬁne-tuned within certain range.

When the battery is empty but the amperage is not at “0”,

it needs to be adjusted.

When the displayed temperature does not ﬁt the actual

temperature, it can be ﬁne-tuned within certain range.

Choose “YES” to reset all the setting to default.

Battery’s actual capacity.

When the battery voltage is higher than this value, the capacity

percentage would be set to 100%. (Only works in “Manual-mode”).

Auto-mode (simple, suggested mode)

This mode is easy for everyone, we suggest customers use the monitor in this mode.

1.Wire and check the current

Thread all the wires from the battery’s positive (or negative) pole through the sensor ring (check

the wiring diagram below) and check the amperage on the monitor. When the wirings are correctly

done, the amperage should be positive when charging and negative when discharging. If the

monitor shows the opposite, turn the sensor ring front side back.

2.Zero the battery capacity

The battery capacity shown on the monitor is not the real capacity when you ﬁrst use this meter. To

measure the battery accurately, the capacity needs to be zeroed. Discharge your battery till empty

and press the “▼” button for 3s to zero the capacity. Then charge you battery till it’s full.

Normally when the batteries are full, the capacity should be 100% on the monitor. If not, press the

“▲” button for 3s to ﬁll the capacity (with the battery charger attaching).

Manual-mode (complex, for professional)

This mode is for people who know their batteries very well and need to monitor the battery status

at the best accuracy. This mode involves accurate value setting, only for professional.

1.Wire and check the current

Thread all the wires from the battery’s positive (or negative) pole through the sensor ring (check

the wiring diagram below) and check the amperage on the monitor. When the wirings are correctly

done, the amperage should be positive when charging and negative when discharging. If the

monitor shows the opposite, turn the sensor ring front side back.
