Passive Balancing hatte ich auch in Erinnerung. Ich tippe mal bei 100%. Kann ich aber nicht mehr prüfen. Mittlerweile sind bei mir die Zellen immer gebalanced.
Ich kopiere hier mal Wiki rein
In passive balancing, energy is drawn from the most charged cell and dissipated as heat, usually through resistors.
Passive balancing equalizes the state of charge at some fixed point—usually either "top balanced", with all cells reaching 100% SOC at the same time; or "bottom balanced", with all cells reaching minimum SOC at the same time. This can be accomplished by bleeding energy from the cells with higher state of charge (e.g., a controlled short through a resistor or transistor), or shunting energy through a path in parallel with a cell during the charge cycle so that less of the (typically regulated constant) current is consumed by the cell. Passive balancing is inherently wasteful, with some of the pack's energy spent as heat for the sake of equalizing the state of charge between cells. The build-up of waste heat may also limit the rate at which balancing can occur.
