5. Battery Pack Electrical Characteristics

5.1 Testing Conditions (Unless Specially Requirements)

Temperature:20±5℃ Related Humidity: 45~75%

Atmosphere Pressure: 86~106kPa

The testing items under the Shipment Voltage(12.8-13.6V )

5.2 Battery Pack Electrical Characteristics

No.	Items	Standards	Testing Methods
1	Internal Impedance	Impedance ≤50mΩ	Under 20±5℃ Environment Temperature , the Usage Frequency of Fully Charge( 1KHz) , Use AC Internal Impedance test machine to test
2	Nominal Capacity	75Ah	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	5A	charging with 5A for more than 0.5h and the added temperature of battery pack less than 20℃.
5	Allowed Maximum continuous discharge Current	30A	Discharging with 30A for more than 0.5h and the added temperature of battery pack less than 20℃.

6. Reliability Test

6.1 Testing condition (Unless Special Requirements)

Temperature:20±5℃ Relative Humidity: 45~75%

Atmosphere Pressure: 86~106kPa

All testing under full capacity(13.2-13.6V)

6.2 Reliability Test

No.	Items	Standards	Testing Methods
1	Vibration Testing	The appearance of battery should not leakage, break or explosion	Fix a charged battery on a vibrating table, vibrate it for 90 minutes in three mutually perpendicular directions at the 0.8mm resonance. The frequency is to be varied at the rate of 1hz/min between 10 and 55 hertz.
2	High Temperature Discharge Testing	The battery should be no remarkable breakage, distortion. Discharge time should not less than 255mins	Place a full charged battery under the environments of 55℃ for 2 hours. Discharge it at the current of 200mA to the cut-off voltage. Then keep it at 20℃±5℃ for 2 hours.
3	Low Temperature Discharge Testing	The battery should be no remarkable breakage, distortion. Discharge time should not less than 180 minute	Place a full charged battery under the environments of -20℃ for 15-24 hours. Discharge it at the current of 200mA to the cut-off voltage. Then keep it at 20℃±5℃ for 2 hours.
4	Constant Humidity & Temperature Testing	The battery should be no remarkable breakage, distortion. Discharge time should not less than180mins	Place a full charged battery under the environments of 40℃ and 90% - 95%RH for 48 hours. And keep it in the room temperature for 2 hours. Then discharge it at the current of 200mA to the cut-off voltage.
5	High & Low Temperature Storage	The battery should be no remarkable breakage, distortion. And charge/discharge normally	Place a full charged battery in a oven with 55±2℃ for2 hours, then keep it under 20±5℃ for 4hrs, then place it in a oven with -20±2℃ for 2 hours, then keep for 4 hours under 20±5℃, cycle as high temperature-normal temperature-low temperature-normal temperature-high temperature for 10 times
