This is one of the best-selling lithium iron phosphate batteries in my shop, the product model is Lifepo4 280AH, it has an ultra-long cycle, up to more than 3500 life cycles; the actual capacity is higher than the specification, the resistance is lower than 0.25mΩ, and the discharge performance is good; Discharge <3%/month. Battery terminals are available in two styles for M6 through-hole terminals and solder studs. Generally, solder studs are easier to assemble. As a new battery technology, DIY DIY battery packs of 12V, 24V, 36V, 48V or larger can be made in series or in parallel. As a new battery technology, it has caused a great response in the industry. Lithium-iron batteries are widely used because they have many advantages and can produce batteries of various capacities.
