The battery life of lithium iron phosphate is theoretically 3000 times of charging and discharging, or 2000 times, but solar street lights are energy storage batteries, which are charged and discharged with low current, which will make the battery have a longer life.
For a ternary battery, the theoretical lifespan currently published is 900 times the best, but the quality of the product varies.
There are also advanced intelligent BMS microcomputer management systems built-in lithium iron phosphate batteries on the market, with overcharge, over-discharge, overcurrent, temperature, and other alarms and triple protection functions, and have the function of good communication with PCs. Automatic charge and discharge management, the monitoring unit automatically measures the charge and discharge current of the battery and performs continuous float charge balance management on the battery.
In general, the life of the iron-lithium battery is better than the three yuan, but the volume is larger.
