Important Safety Instructions

WARNING:
READ AND UNDERSTAND ALL INSTRUCTIONS before using this product. Failure to do so could result in serious injury or death!

SAVE THESE INSTRUCTIONS!

Do’s

1. Do note the warning labels on the battery.
2. Do protect terminals from the short circuit before. during. and after installation.
3. Do wear electrically insulated gloves and use electrically insulated tools.
4. Do wear eye protection and safety-toe boots/shoes.
5. Do handle the battery carefully and secure battery safety.

Don’ts

1. Do NOT operate or store the battery outside of the operating limits.
2. Do NOT wear rings. watches. bracelets. or necklaces when handling or working near the battery.
3. Do NOT expose the battery to flames, incinerators, high temperatures, or direct sunlight.
4. Do NOT put waste batteries into the fire, otherwise, there will be explosions and other dangerous accidents happen.
5. Do NOT lift the battery by the terminal cables.
6. Do NOT vibrate the battery.
7. Do NOT expose the battery and its accessories to water or other fluids and pay attention to moisture-proof.
8. Do NOT connect with other types of batteries.
9. Do NOT disassemble the battery. Removing the battery may cause an internal short circuit, causing decomposition of internal substances, fire, explosion, etc. in addition, dismantling the battery may leak the electrolyte of the battery; if the electrolyte is splashed on the skin, eyes, or other parts of the body, rinse immediately with clean water and immediately go to a doctor.
10. In the event of battery damage, deformation, electrolyte, smell-like leakage, and other abnormalities, do not use the battery anymore. Please send it to the authorized officer of the manufacturer or the appropriate agency for proper disposal. In addition, the batter-leaking electrolyte should be kept away from the fire to avoid an explosion.
11. Do NOT replace the battery without permission, the battery should be replaced by the battery supplier.
12. Do not disassemble or modify the battery. If the battery housing is damaged, do not touch the exposed contents.
13. Batteries can be used in parallel &. series connection. The voltage of batteries must be tested before being used in parallel and ensuring the voltage tolerance within ±0.IV.
14. Do not throw the battery in the garbage.

Connection Tips

1. To connect in series or /and in parallel, batteries should meet the below conditions:

   • The same battery capacity (Ah);
   • From the same brand (as lithium battery from different brands has their special BMS):
   • Purchased in near time ( within three months).

2. Limitation for series connection:
   Up to 4 identical batteries for up to 48V (51.2V).

3. Limitation for Parallel Connection:
   Up to 4 identical batteries for up to 28Ah/ 60Ah/ 400Ah/800Ah.

Installation Instructions

Tools

1. Insulated tools sized to match nuts, bolts, and cables in use of Voltmeter.
2. Personal protective equipment.

Securing battery
The battery can be strapped into place with non-conductive nylon straps or on the ground.

Inspection

1. To check the battery package, type, quantity, appearance, and other components.
2. Check if there is any damage to the battery box.
3. Check the battery terminals and connections to make sure they are clean, and free of dirt, and fluids.
4. All battery cables and their connections should be tight, intact, and NOT broken or frayed.
5. Check torque on terminal bolts.

Note:
Please inform us within 7 days after receipt of the goods if there is anything missing, otherwise, we deem clients have no objection to the goods.

Installation

1. If the battery circuit has disconnected, open and disconnect to isolate the battery.
2. Clean cable connections. Broken, frayed, brittle, kinked, or cut cables should be replaced.
3. Install and secure the new battery. Be careful not to ground the terminals to any metal mounting, fixture, or body part.
4. Connect battery cables ( connect the ground cable last to avoid sparks).
5. Measure the open circuit voltage, which is to prevent the battery reverse or reversing during manufacturing.

Operating

Charging
Never attempt to charge a battery without first reviewing and understanding the charger being used.

Caution:
Always make sure the charging meets the battery’s charging requirement; Never charge a visibly damaged battery; Never charge a frozen battery.

1. Please use a special LiFePO4 charger when charging the battery. Do not use GEL/lead acid/ AGM or other battery chargers, it will hurt the battery and affect the battery life.
2. Please check with us if you use the inverter to charge the battery, must make sure the spec of the inverter and battery fit each other before connecting, or else it may cause damage to the inverter or battery.
3. Never use a charge/inverter/ power supply with a higher charging voltage than the battery charging voltage, it will damage the BMS.
4. Connect the charger leads to the battery, make sure that the charger lead, both at the charger and battery side, connections are tight, then turn the charger on.

Discharging

1. Do not discharge the battery below operating voltage.
2. Do not discharge the battery at rates greater than the maximum continuous current.
3. Do not operate in conditions that will exceed the internal operating temperatures of the battery.

Common Failure

LiFeP04 battery failure solution:

Unable to Charge or Discharge

| Check the Wire Connection
Check the Voltage
Check the connections Between Cells
Unload First then Connect again
Replace BMS

Produce heats when using

| Continues Current is too High
Battery Cell is Not Tightly Connected with each other

Battery Maintenance

1. Check the basic function first, and make sure no damage during the transport. Please test the battery voltage, charging function, discharge function, and display function, if there is any abnormality, please stop the installation and notify us first.
2. After installing the battery according to the installation manual, fully charge the battery before using it for the first time. Fully charged and discharged 3 to 5 times, the battery can reach its maximum capacity.
3. To prolong its life cycle, charge those batteries in time when the capacity is low. If batteries are not charged in time, leaving the battery in a deficient state for a long time will affect the battery life. If those batteries will not be used for a long time, keep it half capacity and floating charge the battery every two months, I hour each time.
4. The battery should be installed in a ventilation, dry and clean environment, avoiding the ignition source, and flammable materials approaching and disconnecting the load (turn off the electrical equipment) during charging.
5. The working temperature of the battery is 5 to 40 °C (The optimal working temperature is 15 to 35 °C). Beyond this temperature range, the performance of the battery may change. It is normal if the capacity changes or equipment operating time changes.
6. Avoid cleaning the battery cases with organic solvents. When an accident happens, do not use carbon dioxide to extinguish the fire.
7. The battery is a consumable item, and the life cycle is limited. So please replace the battery when the battery capacity is lower than 50% of the rated capacity.

Precautions for Transportation

1. The battery is suitable for transportation methods such as automobiles, trains, and airplanes. However, during the transportation process, the sun, rain, and severe vibrations should be avoided.
2. The battery should be packaged with insulating and shockproof material and labeled with fragile characters to avoid damage caused by bumps during transportation.
3. The battery pole should be upward and mark the upward label. Do not put it upside down, place it sideways, etc.
4. The battery pole should be upward and mark the upward label. Do not put it upside down, place it sideways, etc.
5. The battery must be handled gently during transportation and handling. Do not throw at random and avoid collisions.
6. Do not place heavy objects on the battery during transport to avoid damage to the battery.
7. Do not mix transport with flammable, explosive, and sharp metal objects.

Storage
The battery should be stored at a temperature of 5°C – 40°C, with relative humidity< 90% (4D°C ± 2°c) cleaned, dry, and ventilated environment. Avoid contact with corrosive substances and keep away from fire and heat sources. The battery is in a halt-power state of about 50% to 60%. To prevent the battery from over­discharging, it is recommended to charge the battery every 2 months, I hour each time.
