    🔋 Lithium-Ion Battery Conditioning

    For optimal electrochemical performance, new lithium-ion batteries should undergo 2–3 complete charge and discharge cycles before reaching full capacity.

    This stabilization phase allows the internal cell chemistry to achieve balanced ion distribution, ensuring maximum runtime, stable voltage output, and extended cycle life.

    After this initial conditioning period, no further full discharge cycles are required.
