Josh, For the NS Red 100AH HTs check battery dimensions / shelf dimensions carefully. I've a number of them where I needed to put the batteries with the fronts facing the side instead of the front to get them to fit - width is the issue. Some battery shelves are just a hair too small to fit all 4 batteries.
