What Are the Differences between 12V and 24V Lithium Battery
Introduction Battery is used in typical daily life. No matter it is in our car, RV, watch or remote control, battery plays an important role our lives. Usually, we do not need to think about the voltage of a battery, but when working with DC power systems for RV’s boats or off-grid applications, a serious decision needs to be made between 12V and 24V lithium battery. This article will discuss about 12V and 24V lithium battery systems, as well as the differences in 12V and 24V batteries. Here we go! What is 12V Lithium Battery? 12V lithium battery is a battery pack composed of three or four lithium batteries connected in series. The capacity of the battery is determined according to the capacity of a single cell, or the capacity of the battery connected in parallel. It is a new type of safe and environmentally friendly battery. Capacity: There is no standard capacity, based on the specific requirements of electrical appliances or equipment to determine, the general capacity is 2200mA /h, 5AH and 10Ah. Some capacity of electric vehicles up to 20AH or 50AH. The more batteries are connected in parallel, the greater the capacity. According to the physical formula: in the parallel circuit: I total =I1+I2+I3 Volume: The volume of 12V 150Ah lithium batteries should be determined according to the capacity of the battery. There is no uniform specification. The bigger the battery, the bigger the volume Weight: Nowadays, a lot of equipment needs large capacity but low weight of lithium batteries. Such as electric vehicles, it used to use lead-acid batteries, but now many electric vehicles into lithium batteries, because lithium battery is of large capacity, light weight and small size. Charge and Discharge Current: The charge and discharge current of lithium battery ARE determined according to the

Does LifePO4 battery cells can be charged with Lead Acid charger
Overview “Can LiFePO4 battery cells be charged with a Lead Acid charger?” This is the question we recently get from our customers. Please find below the answers to why it shouldn’t be done. Simple answer: it is not recommended, because you have to be VERY CAREFUL and you SHORT your battery life. Charging Conditions Much like your cell phone, you can charge your LifePO4 batteries whenever you want. If you let them drain completely, you won’t be able to use them until they get some charge. Unlike lead-acid batteries, LifePO4 batteries do not get damaged if they are left in a partial state of charge, so you don’t have to stress about getting them charged immediately after use. They also don’t have a memory effect, so you don’t have to drain them completely when charging LifePO4 batteries can safely charge at temperatures between -4°F – 131°F (0°C – 55°C) – but we recommend charging in temperatures above 32°F (0°C). If you charge below-freezing temperatures, you must make sure the charge current is 5-10% of the capacity of the battery. What About During Storage? LifePO4 batteries are easier to store than lead-acid batteries. For short-term storage of 3-6 months, you don’t need to do everything. Ideally, leave them at around 50% state of charge before storing. If for long-term storage, it is better to store them at a 50% state of charge and then cycle them by discharging them, recharging them and then partially discharging them to approximately 50%, every 5-12 months. The Key Differences between LifePO4 Battery cells and Lead-Acid Batteries When Charging LifePO4 battery cells can charge at a much higher current and they charge more efficiently than lead-acid, that’s meaning they can be charged quickly. LifePO4 batteries do not need to be charged if they are partially discharged.
The best way to charge the lithium iron phosphate cell
Everything you need to know about charging lithium iron phosphate cell (LiFePO4) batteries Even switching from lead-acid batteries to lithium iron phosphate cells can be daunting. Charging the battery correctly is very important and directly affects the performance and life of the battery. Learn how to charge LiFePO4 batteries to maximize your investment. Charging conditions Just like your mobile phone, you can charge the lithium iron phosphate cells at any time. If you let them run out completely, you won’t be able to use them until they get a certain fee. Unlike lead-acid batteries, lithium iron phosphate batteries will not be damaged even if they are partially charged, so you don’t have to worry about charging them immediately after use. They also have no memory effect, so you don’t need to use them up completely before charging. LiFePO4 batteries can be safely charged at temperatures between -4°F – 131°F (0°C – 55°C), however, we recommend charging at temperatures higher than 32°F (0°C). If you do charge at a temperature below the freezing point, you must ensure that the charging current is 5-10% of the battery capacity. How to charge lithium iron phosphate cell The ideal way to charge a lithium iron phosphate cell is to use a lithium iron phosphate battery charger because it can be programmed with the appropriate voltage limit. Most lead-acid battery chargers can do this job well. The charging curves of AGM and GEL usually fall within the voltage range of lithium iron phosphate batteries. The voltage limit of wet lead-acid battery chargers is often higher, which may cause the battery management system (BMS) to enter a protection mode. This will not harm the battery; however, it may cause a fault code to appear on the charger display. The LiFePO4 battery uses the same constant current
