Hey Richard, yes the Commercial Grade Battery Box for Group 4D Batteries # 329-HM408 could be used to protect LifePo batteries on the tongue of your trailer. I know it says it's for Lead Acid batteries but it can for sure be used with your style of battery as well as long as the dimensions of your battery would match this box. This box has internal dimensions of 21-3/16" long x 9-5/8" wide x 11-1/8" tall. How do you like the life of your battery? They are supposed to last a lot longer.
