Planning your build

The previous description mentions energy storage, solar lighting, robotics, portable electronics and electric mobility as possible applications. Suitability depends on your pack design and power requirements. Use a charger and BMS suitable for this lithium-ion cell, and confirm critical ratings and any certifications with the manufacturer's documentation before assembly. The earlier claim of built-in overcharge protection conflicts with the listed unprotected cell specification and has not been repeated here.
