From the project

Small low-power photovoltaic MPPT module with LTO battery

Battery module with LTO cells. This module was primarily designed for use in autonomous outdoor devices powered by a solar cell. This is possible thanks to the use of LTO cells, which have a wide range of operating conditions and require minimal care. The device can therefore work in outdoor conditions all year round (tested in Central European conditions).
