4. Product Performance
No. | Items | Standards | Testing Methods |
| 1 | Internal Impedance | Impedance ≤60mΩ | Under 20±5℃ Environment Temperature , the Usage Frequency of Fully
Charge( 1KHz) , Use AC Internal Impedance test machine to test
(HIOKI3555) |
| 2 | Nominal Capacity | 20Ah | 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 | 30A | charging with 30A for more than 0.5h and the added temperature of
battery pack less than 15℃. |
| 5 | Allowed Maximum continuous discharge Curren | 30A | Discharging with 30A for more than 0.5h and the added temperature
of battery pack less than 15℃. |
| 6 | Over Current Protection | 120A～150A | Using electron load connect with output side, discharge with 120A
for about 2sec Discharge with 150A for less than 20 millisecond. |
| 7 | the delay time of over current protection | 5.0-20.0ms (≈150A) | Using electron load connect with output side, discharge with more
than 150A 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. |
| 9 | 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 |
| -20℃ | 0℃ | 25℃ | 55℃ |
| 0.2C | 60% | 80% | 100% | 95% |
| 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 (≥40V)of the battery pack. The battery should have load . |
6. Warning&Tips
Please read and follow the specification and caution remarks on
battery surface before use the battery. Improper use may cause
heat, fire, rupture, damage or capacity deterioration of the
battery. SHENZHEN TOPBAND NEW ENERGY CO.,LTD. Describes is not
responsible for any accidents caused by the usage without following
our specification.
