12.8V 400Ah Off-grid Lead Acid Replacement RV Boat Backup Power Battery

12.8V 400Ah Off-grid Lead Acid Replacement RV Boat Backup Power Battery

With the 12V 400Ah we built an energy dense battery ready for long nights in the ice hut or long days rolling the open road in your Rv. Packed with Lithium iron Phosphate (LiFeP04) technology this is a battery built to last. With a lifespan of 6,000 charge cycles this battery will last up to 3 times longer than your typical SLA battery,providing exceptional value over time for electric vehicles owners, off grid solar users, and truck load.
