Battleborn GC3 270 ah Batteries


Recommended Posts

I was able to install 2 Battleborn GC3’s in the existing battery compartment. (2016 Oliver Legacy Elite II).  I replaced 4, 6 volt batteries. The battery tray had to come out. The new batteries are mounted on a board that can be unscrewed and slid out if necessary for some reason in the future. The exchange tripled the power and halved the battery weight.


For some reason photos are always upside down on import  is there a solution?

I do not have a clue but flipped it for you.


I am hazy about how you mounted the board to the compartment, some additional (upright) pics would be helpful. The board appears to be regular particle board... Are you aware of its unsuitability for a structural mount? Especially in a potentially wet area?
