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 3000 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. DIY battery packs of 12V, 24V, 36V, 48V or larger configurations can be made in series or in parallel. Iron-lithium batteries have many advantages and can be used for various electric vehicles, home energy storage, communication energy storage and solar energy storage off-grid needs.
