Advantages of Lithium Iron Phosphate (LiFePO4) batteries for solar street lights

图片
Lithium batteries for solar street lights are becoming an increasingly mainstream solution. We all know that lithium batteries are still very expensive considering other types of lithium batteries, but it's fair to say that they are becoming more affordable in solar street light integration. The cost of lithium batteries has dropped by almost 80% in the last 6 years. There are different types of lithium batteries available for solar street light systems. Our experience shows that the best solution is   LiFePO4 batteries .   Advantages of Lithium Iron Phosphate (LiFePO4) batteries for solar street lights. 1. Lighter Compared to lead-acid batteries, LiFePO4 batteries are almost four times lighter. For example, a 150ah lead-acid battery weighs about 50kg/110lbs, while the other side of the LiFePO4 battery is only 15kg/30lbs. For many solar applications, this brings huge benefits in terms of lower installation costs and faster project execution. 2. Safety Lithium iron phosphate (L...

Overcharging will cause the battery to heat up internally and prolonged or excessive charging may cause a fire

    3. Use the correct terminal mounting hardware Use 20 mm long bolts for batteries 90Ah and above. 15 mm bolts for batteries 60Ah and below. If in doubt, measure the depth of the threads in the cell and make sure the bolt will be near but not touching the bottom of the hole. From top to bottom, you should have a spring washer, flat washer, and then the battery interconnects.   About a week after installation, check that all terminal bolts are still tight. Loose terminal bolts can result in a high resistance connection, robbing your EV of power and causing excessive heat.   4. Never overcharge/discharge your batteries! The most common causes of premature failure of  LiFePO4 batteries  are overcharging and overdischarging. Even one occurrence can cause permanent damage to the battery, and such misuse can void the warranty. A battery protection system is required to ensure that no cell in your battery pack is likely to exceed its nominal operating voltage ra...

LiFePO4 Care Guide: Maintaining Your Lithium Battery

图片
Because LiFePO4 chemistry lithium batteries are one of the most powerful and long-lasting battery chemistries available, they have become popular in recent years for a range of applications. If properly maintained, they will last a decade or more. Please take a moment to read these tips to ensure you get the longest service from your battery investment.   1. Frequent charging and shallower cycling With lithium batteries, the battery will last longer if you avoid overly deep discharges. We recommend sticking to a maximum of 70-80% DoD (depth of discharge), except in emergencies.   2. Clean the terminals before installation The terminals  on top of the battery  are made of aluminum and copper and will form an oxide layer over time when exposed to air. Clean the battery terminals thoroughly with a wire brush to remove oxidation before installing the battery interconnect and BMS module. If bare copper battery interconnects are used, they should also be cleaned. Removing ...

Charging Lithium Iron Phosphate (LIFEPO4) Batteries

图片
How do I charge a LiFePO4 battery? This is one of the most common questions we get from our customers. The answer is simple: use a LiFePO4 battery charger, of course. When charging LiFePO4 batteries, make sure you are not using a charger for other lithium-ion chemicals that are typically designed for higher voltages than what is required for LiFePO4. We are often asked if we can use a lead-acid battery charger to charge LiFePO4. The short answer is yes, as long as the voltage is set within the parameters acceptable for LiFePO4 batteries.   Charging Guidelines LiFePO4 batteries  do not need to be recharged after each use if they are not fully discharged. liFePO4 batteries are not damaged when they are in the partially charged state (PSOC). You can charge the LiFePO4 battery after each use or after it has been discharged to 80% DOD (20% SOC). If the Battery Management System BMS) disconnects the battery due to low voltage (voltage will be <10V), use the LiFePO4 battery charge...

Replacing Ni-Cd rechargeable batteries with Ni-MH rechargeable batteries in solar lights is a better choice!

图片
Many people are asking "Can I use Ni-MH (Nickel Metal Hydride) batteries in my solar street lights to have   Ni-Cd (Nickel Cadmium) batteries ?" The answer is, yes! Not only can you replace them with Ni-MH, but they are a better battery choice because they have advantages that their Ni-Cd counterparts do not.   Ni-MH battery advantages   1. No memory effect (compared to Ni-Cd). Ni-MH can be partially charged (for example, on a cloudy day) and fully charged to maximum capacity on the next sunny day. There is a small amount of discharge (trickle discharge) during storage, so it is best to put  Ni-MH batteries  in your garden solar lights before dawn on a sunny day. They will then be ready for you to enjoy the nighttime fun.   2. Long shelf life. They can remain unused for between 3 and 5 years. However, we recommend that you use new Ni-MH rechargeable batteries as soon as possible to ensure that these solar lights always shine.   3. Ni-MH rechargeab...
