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. |

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 | |
