1. About us

Shenzhen Topband Battery Co., Ltd, a company professional to do LiFePO4 battery, which is founded in 1996 and listed in Shenzhen in 2007.There are over 300 R&D engineers and about 3,000 employees in the 70,000 square meters Topband industrial park.We can provide One-Stop Solution of new energy, from cell, BMS/PCM to battery pack assembling.

This rechargeable LiFePO4 battery pack TB-BL12125F support Bluetooth communication function. Through Android and IOS APP, can read the battery status and information. Especially due to the Android system’s openness, different smart phone manufacturer will have their own different Bluetooth hardware version and customized feature Android systems. It is necessary for the customer to confirm whether the phone is compatible for the APP.

3. Electrical Characteristics & Test Condition

Testing Conditions: Ambient Temperature: 25±5℃; Huminity:45%~75%.

No.	Items	Standards	Testing Methods
1	Internal Impedance	Impedance ≤20mΩ	Under 20±5℃ Environment Temperature , the Usage Frequency of Fully Charge( 1KHz) , Use AC Internal Impedance test machine to test
2	Nominal Capacity	125Ah	Rest for 0.5~1 hour after fully charge, Using electrical loader to connect with the battery output port, and discharge with constant current 0.2C till it can’t discharge. Do the cycle three times, if there is one time that the discharge time is equal or more than 285minute , you can stop.
3	Short circuit protection	No load ability after short-circuit .comeback capability of loading after remove the lead away,	Short the pack with the lead (<50mΩ). If remove the lead away, connect the electronic loader with P+,P- of protection board again, so load ability comes back.
4	Allowed Maximum continuous charge Current	60A	charging with 15A for more than 0.5h and the added temperature of battery pack less than 15℃.
5	Allowed Maximum continuous discharge Curren	60A	Discharging with 15A for more than 0.5h and the added temperature of battery pack less than 15℃.
6	Over Current Protection	50A～70A	Using electron load connect with output side, discharge with 50A for about 2sec Discharge with 70A for less than 20 millisecond.
7	the delay time of over current protection	5.0-20.0ms	Using electron load connect with output side, discharge with more than 70A and record the voltage wave of output side with oscillograph . Numerating the time of voltage from wave to zero for voltage
8	cycle life	Discharge Capacity ≥80%	Discharge it with the current of 1C to the cut-off voltage, and store it for 15min.Charge a battery with the current of 1C, then keep the voltage and current constant and continue to charge it until completed . After storing the battery for 15min. The test is to be conducted as per the above cycles. The cycle should be 2000 times. At the 2001 times discharge capacity should not be less than ≥80% with 0.2C.
10	Charge Retention	remain capacity≥90%	At 20±5℃ completely charge and store it for 28days,and then discharge it with 0.2Cto the cut-off voltage. (We suggest charge the battery every three months)
11	Over Discharge Protection furbish	Charging With0.2C	Charge the battery with 0.2C for 5min and measure the output voltage (≥25V)of the battery pack. The battery should have load .
12	Discharge Temperature Characteristics	The ratio between discharge capacity and charge capacity should be not less than the following value	At 20±5℃ discharge the battery with the current of0.2C to the cut-off voltage and record charge capacity. Store the battery at the following temperature for 2h and discharge the battery with 0.2Cto the cut-off voltage.
		Discharge Current	Discharge Temperature
		Discharge Current		-20℃	0℃	25℃	55℃
		0.2C	60%		0.8	1	0.95

4. Storage and Transportation

1) Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.
2) Battery should be stayed in the ware house -20℃～35℃ where it’s dry, clean, shade, and well-ventilated.
3) The battery should be stored in 50% SOC during transportation.
4) The battery need to be charged every 6 months if out of use
5) Keep the battery against dropping, turning over and serious stacking during loading.
