12V28Ah LiFePO4 Battery
The lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as a positive electrode material.
The long-life lead-acid battery has a cycle life of about 300 times and a maximum of 500 times.
The lithium iron phosphate power battery has a cycle life of more than 2,000 times and a standard charge (5 hour rate), which can reach 2000 times. The same quality lead-acid battery is "new half year, old half year, maintenance and maintenance for half a year", up to 1~1.5 years, while lithium iron phosphate battery is used under the same conditions, the theoretical life will reach 7~8 years. Considering comprehensively, the performance price ratio is theoretically more than four times that of lead-acid batteries. High-current discharge can be quickly charged and discharged with high current 2C. Under the special charger, the battery can be fully charged within 1.5 minutes of 1.5C charging, and the starting current can reach 2C, but the lead-acid battery has no such performance.
