Small low-power photovoltaic MPPT module with LTO battery

README

SOLARMINIBAT01

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).

Features:

• LTO batteries (4x LTO1865) cells
  • 1.3 Ah (per cell)
• MPPT tracker for LTO batteries charging from solar cell
• Battery gauge for battery charge state measurement
  • I2C interface
  • LED indication
• Output switching voltage regulator
  • Standard output voltage 3v3
