Review: Great price for a great product - I built this battery box to power my garden fountain when my solar panel is not seeing sun light. I purchased a relay on desertcart that switches seamlessly between solar and battery. I installed a charging port with an LED. I wanted the LED to turn off not just when I unplugged the charger but when the charger entered the float mode. It took some time to properly program the relay with the correct settings and I am pleased to say that the relay works perfectly. As advertised this relay can work both for charging or discharging but you have to chose one or the other it can't do both at the same time. Now as I said the LED comes on when my battery is charging and goes off when my battery is fully charged. This is a well priced for such a perfect relay. I definitely recommend it for any DIY project.
Review: This protection board is compatible with a wide range of devices - great quality and value . - This multifunctional protection board has become an essential component for when we are camping and using our truck battery. We mainly use it in protecting our truck battery from discharging when running a portable fridge while we are camping. The LCD display offers real-time monitoring of voltage levels during charging and discharging. This level of precision enables me to keep a close eye on the health of my devices and prevent potential damage from voltage fluctuations. This will detect voltage drops below a predefined threshold and promptly disconnects the power supply, ensuring that my devices are shielded from operating under unsafe conditions. Whether it's during the charging or discharging phase, this protection board ensures that my devices operate within safe voltage parameters. This protection board is compatible with a wide range of devices, from battery-powered gadgets to charging systems. Its versatility makes it suitable for various applications, from DIY electronics projects to household electronics protection. Knowing that my devices are equipped with a robust protective barrier against voltage-related issues, even in my absence, offers me a sense of peace and confidence. Highly recommended.

## Features

- It has a 2-in-1 charging mode (battery overcharge protection) and discharging mode (battery low voltage protection). The charging mode can be used for solar charging, and the battery automatically disconnects when it reaches the set voltage. The discharging mode can be used for battery low voltage protection.
- Two low-power modes: automatic mode and manual mode. Manual mode consumes 0 power after the relay disconnects, and manual button reset is required after disconnection;
- In automatic mode, the relay enters a low-power mode after disconnecting (LED turns off after 60s without any button action, and the LED resumes display when a button is pressed again). Standby current is 5mA (18V), and it automatically restarts when the voltage is restored.
- The device has an internal flash storage module, so all settings can be restored after a power off.
- Maximum 40A current, operating voltage from 5V to 60V.Supports a 99 seconds start delay, 99 seconds disconnect delay, and a 99:59:59 hours timer disconnect timer.

### ⭐⭐⭐⭐⭐ Good for shutting things down when they are supposed to!
*by F***D on May 31, 2025*

Great little gadget. I have built some battery packs from scratch and I used them to ensure the voltage is never below a certain threshold. To me it adds a layer of protection so you arent purely relying on your BMS, if your even using one! I think I have like 3 of these. Handy! I really wish they made a HIGH voltage disconnect.
