Coupon code "15USAFF" brings this RVPozwer 12.8V 100Ah battery down to $104, well below its original $311.64 price. This lithium iron phosphate model is rated for roughly 15,000 charge cycles at shallow discharge depths, far beyond the few hundred cycles typical of a comparable lead-acid battery. That difference matters most for RV, marine, and off-grid solar setups where the battery gets cycled often, since it can go years longer before needing replacement.
