The NOCO BG27 is a Group 27 battery box for automotive, marine, RV, deep-cycle, and lithium-ion batteries, including cars, boats, campers, travel trailers, pontoon batteries, and more. This battery box features an all-new rugged and snap-lock design making it more durable and easier to install than ever before. Its simplified mounting allows for installation without a battery strap using pre-drilled internal pilot holes or a battery strap mount for more demanding applications. It safely protects batteries from unwanted battery movement, accidental shorting of battery terminals, collects battery acid, and allows adequate ventilation. And it meets with the United States Coast Guard (USCG) Code of Federal Regulations 183.420 and American Boat and Yacht Council (ABYC) E-10.7 specifications. It includes the BG27 Group 27 Battery Box, 48-Inch Battery Hold-Down Strap, Battery Mounting Tray, and Four (4) #8x1-Inch Self-Tapping Screws.
