| status | Status description |
Sleep function |
When the battery is no abnormality, static 20S, BMS into the system sleep, reduce consumption, then charge and discharge MOS in the open state, charging or discharge can be activated to normal working condition. |
Over discharge power down function |
When the battery pack into the over-discharge state, and the minimum voltage is less than the over-discharge protection value, BMS will minimize power consumption, turn off the charge and discharge MOS tube, you need to charge to activate. |
| Charge condition | Charger must be standard charger can be charged |
| Assemble the parallel battery pack | Newly assembled parallel battery packs or reassembled parallel battery packs require a new assembly of parallel battery packs or reassembly of parallel battery packs charging firstly, then they can be used for discharge. |
| Display LED | The display is composed of two interfaces. The first interface shows the total voltage, current, maximum temperature and minimum temperature of the company LOGO and battery pack, and SOC. The second interface shows the battery voltage of each section of the battery pack. |
