What is the stud size on the terminals? 1/2"? 3/8"? Can't find this info in your online manual.



Great question! They are M8x1.25 - for a ring terminal it would be best to use a 5/16" diameter terminal. The recommended torque for tightening these terminals is 20 Ft-lbs


Can these batteries be mounted in a hanging position? I want to cut up and weld a standard rack so rails are horizontal and about a couple feet off the ground. My goal is to have a free standing stable rack to put them in. The ears on the battery would rest on top of the rails (screwed in, as normal with rack mounting), with the battery hanging below (battery terminals up) - is this ok?



We do not recommend this; the ears should only be used to prevent movement and not the sole point of support. To make this work, a support that holds the rear of the battery (now the bottom) would need to be added.


How many of these are you able to run in parallel?
