| Discharge Switch | Remotely disconnects all discharge loads from the battery |
| Storage Use | Discharge switch can be turned off when storing the battery |
| Remote Isolation | Allows charge or discharge control through the app |
Turning the charge switch OFF prevents the battery from accepting charge from any charging source, including a DC battery charger.
Turning the discharge switch OFF prevents the battery from running appliances by disconnecting all loads from the battery. This is ideal when storing the battery.
🧠 Internal Battery Management System
The BMS is the internal control system that manages battery safety, performance, and protection.
| BMS Function | Details |
|---|---|
| Discharge Capacity Control | Manages maximum discharge load |
| Input Charge Rate Control | Manages accepted charge input |
| Operating Temperature Monitoring | Monitors battery temperature |
| Low Voltage Disconnect | Protects the battery from excessive discharge |
| Reset Voltage Control | Allows recovery after protection events |
| Bluetooth Capability | Enables app-based monitoring and control |
| Protection Parameters | Controls safety limits for the battery |
The BMS supports safe charging and discharging with over temperature protection, under voltage cut-off, over voltage cut-off, and internal short circuit protection.
🔘 BMS Reset Switch
In most cases, the BMS will reset when a battery charger is connected. If it does not reset, the built-in BMS reset switch can help wake the battery after excessive discharge or overload.
How to Use the BMS Reset Switch
| Step | Action |
|---|---|
| 1 | Connect the battery to a 240V battery charger |
| 2 | Turn the charger ON |
| 3 | Press and hold the BMS reset switch for approximately 30–90 seconds |
| 4 | Once the charger starts charging normally, release the switch |
| 5 | Allow the battery to charge normally |
Some chargers require voltage to activate charging and may not reset the BMS under normal conditions. If available, set the charger to power supply mode to activate the BMS, then switch back to battery charger mode after the reset is successful.
