Regarding Pins of SPV1050

I'm mounting SPV1050 on PCB. In my application, I'm using a PV cell as input to the IC and takes the output from Vbatt to charge a battery. I am not using LDO or anything extra.. no use of store too. Is it right if I make Pin 5,6,7,8,11,12,17 open circuit?

Pins 5 and 6 are inputs (LDO1_EN, LDO2_EN) and should be connected to GND when the LDOs are not used.

You can leave the remaining pins floating.

Pin 7 and 8 should be floating right? Are you sure?

Yes, pin 7 (BATT_CHG) and pin 8 (BATT_CONN) are outputs and indicators that can but do not have to be used.
