Mow 1 acre 3 times vs less than once on 5 yr old? lead acid batteries I 
got from Harold.  I don't recall the amp hours.
 
For inrush - a guy on the FB page sells a slow start device although I am 
not using it on my install.
 
The state of the art in batteries and chargers has increased so much in 
the last 3-5 yrs its really amazing.  And they cost less than lead acid 
batteries.  I paid $800 for the battery, charger, shunt and controller kit 
on Amazon.   Literally hundreds of youtube videos on these topics.
