YX850 Undervoltage Cut Off Module - 5V-48V Automatic Power Failure Switch, Standby Battery Backup For Lithium Batteries

Protect your batteries and keep your stuff running with this clever little YX850 module!

Here's what it does: It automatically switches your device to a backup battery when the main power fails.

Imagine you have a security camera, router, or LED lights running off a main DC power supply (like a wall adapter).

If that power cuts out, this module instantly switches the load to a connected standby lithium battery.

When main power comes back, it switches back and starts recharging the battery.

It's a simple, affordable uninterruptible power supply (UPS) for DC devices.

It works with a wide range of voltages from 5V to 48V, making it super versatile.

It can handle charging currents up to 10A.

The module itself is compact, about 2.4 x 1.2 x 0.7 inches, and weighs only 22g.

Installation is straightforward with its two mounting holes.

Use it for DIY projects, solar setups, car electronics, or anywhere you need to prevent data loss or downtime during a power blip.

It's a digital low-voltage protector that disconnects the load to prevent over-discharging your precious lithium battery.

A must-have for any tinkerer or anyone who needs reliable backup power!
