应该是3.0v左右,不过大多数电量显示和电调好象3.6v就会报警或者保护。看到的中文资料说不要放到3.6以下
最权威的应该是wikipedia,如果没有被封的话

摘录:
The voltage of a Li-poly cell varies from about 2.7 V (discharged) to about 4.23 V (fully charged), and Li-poly cells have to be protected from overcharge by limiting the applied voltage to no more than 4.235 V per cell used in a series combination. Overcharging a Li-poly battery will likely result in explosion and/or fire. During discharge on load, the load has to be removed as soon as the voltage drops below approximately 3.0 V per cell (used in a series combination), or else the battery will subsequently no longer accept a full charge and may experience problems holding voltage under load. |
