Note for LiFepo4 Prismatic Cells
• Users should configure a suitable BMS for strictly monitoring, management and protection.
• The reversal charging is forbidden. Correctly connect the battery cells with Positive Pole and Negative Pole, otherwise short circuit would happen due to wrong connection on +/- terminal then cause damage and safety problem.
• No matter what kind of charging mode is, once the temperature of the cell is above the maximum charging temperature, charging should be stopped.
• If the batteries kept unused for a long time, it should be charged and discharged at the standard model every 3 or 6 months. Store the batteries in the state of 20%-30% SOC (Voltage scope: 3.275V~3.305V).

Test Methods and Condition |
Criteria |
|
Heavy impact |
The battery is placed on the impact table, and the 10kg weight is free to fall from the height of 1m, and the battery that has been fixed on the fixture (the surface with the largest battery area should be perpendicular to the table) |
The battery does not ignite or explode |
|
Thermal shock |
The battery was placed in a hot box and the temperature was raised to 130 ± 2 ° C at a rate of (5 ± 2 ° C) / min and held for 30 min. |
The battery does not ignite or explode |
|
High temperature test |
After standard charging, the battery is placed in an oven at 90 ° C for 4 hours, then the battery is discharged at a constant current of 0.2CA to 2.50V, and then cycled 3 times. |
Capacity recovery rate ≥75% |
|
Overcharge |
After standard charging, the battery with the thermocouple is placed in the fume hood. The battery and the sliding varistor are connected in series to the constant current and constant voltage source. The voltage is adjusted to 4.8V. The current is adjusted to 5.0CA through the sliding varistor, and then the battery is 5.0CA. Charging, monitoring battery temperature changes during the test, when the battery temperature dropped to about 10 ° C lower than the peak, the experiment was terminated. The current is not required to maintain 5.0CA during the test. |
The battery does not ignite or explode |
|
Short circuit |
Place the battery with the thermocouple in the fume hood, short-circuit its positive and negative poles (the total resistance of the line is not more than 100mΩ), monitor the battery temperature change during the test, and end the test when the battery temperature drops to about 10 °C lower than the peak value. . |

Operation Instruction to Lifepo4 Prismatic Cells
▪ Charging
Charging current Cannot surpass the biggest charging current which in this specification book stipulated.
Charging voltage Does not have to surpass the highest voltage range which in this specification book stipulated.
Charge temperature The battery must carry on the charge in the ambient temperature scope which this specification book stipulated.
Uses the constant electric current, and the constant voltage way charge, the prohibition reverse charges. Incorrect connection of the battery positive electrode and the negative terminal can damage the battery.
▪ Discharging current
The discharging current does not have to surpass this specification book stipulation the biggest discharging current, the oversized electric current electric discharge can cause the battery capacity reduction and to cause the battery overheat.

Other The Chemical Reaction
Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period of time without being used.
In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage.
If the batteries cannot maintain a charge for long periods of time, even when they are charged correctly, this may indicate it is time to change the battery.

# Battery appearance visual check: Once batteries received, pls check if the batteries with scratches or impacted. If yes, pls contact us at the first time.
# Use insulating plate between batteries for better isolation in case short circuit happens to cause battery damage.
# Do correctly connect the battery cells with Positive Pole and Negative Pole, otherwise short circuit would happen due to wrong connection on +/- terminal.
# DO NOT Power On the batteries before checking. Connect the batteries in series/parallel to a battery pack firstly. Do not Charge the battery pack at this step!
# Use the Multimeter to check the voltage of each battery cell, then connect the battery cells to 12V/24V/48V Battery Pack and then check the voltage of the whole battery pack.
# Connection Use Notice:
Do keep the battery cells at same voltage if you are going to connect them in series or parallel. If not, pls connect the battery cells in parallel (no charging at this step) to balance the voltage.
# Ensure the Voltage parameters and Correct Connection of the batteries normal, YOU CAN CHARGE/USE the Battery Pack.
