Electrical & Protection Specifications
Electrical values shown below are typical reference values for preliminary selection. Protection options are configurable; final thresholds, current capability and PCM/BMS are confirmed according to the actual cell and application requirements.
| Standard Charge Current | 0.2C (0.88A) | Standard Discharge Current | 0.2C (0.88A) |
|---|---|---|---|
| Maximum Continuous Charge Current | 0.5C (2.2A) | Maximum Continuous Discharge Current | 0.5C (2.2A) |
| Discharge Cut-off Voltage | 11.00 V | Energy | 65.12 Wh |
| Cell Configuration | 4S2P | ||
| NTC Thermistor | NO / Optional | C-rate | 1.0C |
| Self-Discharge Rate | ≤ 3%/month (at 25°C) | Short-Circuit Protection | Yes |
| Over-discharge Protection Options | For multi-series battery packs, the PCM/BMS is selected based on the required continuous current and peak/inrush current (including OCP trip thresholds, delay settings, and current-handling capability), together with per-cell voltage monitoring requirements. After the hardware version is selected, the over-charge and over-discharge thresholds (and balancing strategy, if applicable) are finalized. Alternative PCM/BMS versions are available if specific protection thresholds or delay requirements are needed. |
Overcharge Protection Options | For 2S, 3S, 4S and higher-series battery packs, overcharge protection is configured on a per-cell basis according to the cell voltage, series configuration and selected BMS/PCM. Final thresholds are confirmed according to the actual cells and application requirements. |
| Overcurrent Protection Options | Multiple PCM/BMS options are available (e.g., 0.2A / 0.5A / 1A / 2.5A / 5A / 7A / 9A, with higher-current solutions available for suitable battery packs). OCP threshold and delay depend on the selected protection circuit. Our engineers will match the PCM/BMS to the required continuous current, peak current and application requirements. | ||
