Charge cut-off and Protection:
| Description | Parameters | Remarks |
|---|---|---|
| Charge cut-off Voltage | 3.65V | Terminating charge process when cell OCV reaches 3.65V. |
| First Over-charge Protection | >3.7V | Limiting charge current to 0 when cell OCV reaches 3.8V. |
| Second Over-charge Protection | >3.9V | Limiting charge current to 0 when cell OCV reaches 4.0V. Locking BMS before the problem is identified and resolved. |
| Discharge cut-off Voltage | 2.5V | Terminating discharge process when cell OCV reaches 2.5V. |
| First Over-discharge Protection | 2.0V | Limiting discharge current to 0 when cell OCV reaches 2.0V. |
| Second Over-discharge Protection | 1.8V | Limiting discharge current to 0 when cell OCV reaches 1.8V. Locking BMS before the problem is identified and resolved. |
| Short Circuit Protection | Prohibit Short Circuit | Cutting off overcurrent devices (fuses, circuit breakers). |
| Charging Time Protection | <8h | Terminating charge process when charging time exceeds 8 hours. |
Battery Cells Features:
- 1 cell has 100AH 3.2V (4 cells = 100AH 12.8V total)
- Bigger cells mean better safety and more power
- Safety Pressure Release Valve
-
- Standard new safety technology for high quality batteries.
- Prevents explosion caused by excessive internal pressures due to overcharging, short circuit, excessive temperature, battery deformation or puncture.
- Safety valve on top if a very important for explosion-proof barrier. When pressure inside the battery is build up, the safety valve opens to avoid explosion.
- No Memory Effect
- Rechargeable batteries work under conditions that are often not fully discharged, and the capacity will quickly fall below the rated capacity. This phenomenon is called the memory effect. There are memories like nickel-metal hydride and nickel-cadmium batteries, but lithium iron phosphate batteries do not have this phenomenon. No matter what state the battery is in, it can be used with charging, no need to discharge and recharge.
