LTC4065L Charging Voltage

Hello;

 

We have two questions about LTC4065:

1. In datasheet; preset voltage is 4.1V for LTC4065L-4.1; but in operation State Diagram; it says <4.0V decision. When will the chrager stop charging? @ 4.0V or 4.1V?

2. Can it support multiple Cell in parallel charging?

Thanks;
