This Solar Power Manager for 12V Lead-Acid Battery V1.0 is a DFRobot Original product that has been designed with all of the fancy bells and whistles you could imagine. Manufactured specifically with IoT, portability and solar power in mind, the module offers two power input methods and four power output ports so as to accommodate a wide range of different applications.

For power input, this module accepts 12V Lead Acid Battery, AC Adapter, as well as Solar Panel supply, while for output this module offers two 5V 2.5A USB ports (USB1 and USB2) as well as 5V 5A OUT1 and 12V 8A OUT2 screw terminals. However, the USB1, USB2 and OUT1 outputs all share a maximum 5A drive with 8A peak drive, but as long as you don’t overload these with more than 40W simultaneous draw, you can power up to three devices, modules or components from battery or Solar Power without concern.

Finally, just to add the cherry on top of an already feature-rich cake, each of the input/output ports is also complemented by a full range of safety and protection features, including overcharge and overdischarge protection for the batteries, as well as backflow, reverse connection, short circuit and overheating protection for all of the different ports on the board. These help to protect you as a user, but also keeps your batteries and connected Electronics Modules safe from unexpected damage – which is especially important when dealing with variable solar power.

Note: If you're looking for a similar type of solar charging module, but for Lithium batteries instead of Lead-Acid, check out our Solar Power Manager for 9V/12V/18V Panels.
