Our Drone after a Battery failsafe passes to RTL .then to LAND due to Critical fail safe and the drone passed the home point and crashed far away from it .
It is the first time that there is some much difference between the home point and the RTL Landing point
We will much appreciate if you could provide any ideas what will be the reasons that could provoke this error ?

There were a number of problems.
During Land, your GPS started to glitching. Even you had a second GPS onboard, but was not configured for use, so EKF was not able to use the second GPS. Basically it was not sure about where it is at all.
Due to very low battery voltage it was not able to climb anymore, plus it seems that motor3 maxed out during the descent (perhaps under voltage protection, or simply not enough voltage).
So during Landing, Copter lost position control, it kept level, but drifted with the wind during descent. Once you switched to rtl again, there were no juice left in the batteries to do anything.
