BMS stands for Battery Management System. The BMS protects the cells from getting damaged — most commonly from over or under-voltage, over-current, high-temperature, or external short-circuiting. The BMS will shut off the battery to protect the cells from unsafe operating conditions. All Will Nine batteries have a built-in BMS to manage and protect them against these types of issues.
Lithium batteries are rechargeable batteries in which lithium ions move from the anode to the cathode during discharging and back when charging. They are popular batteries for use in consumer electronics because they provide high energy density, possess no memory effect and have a slow loss of charge when not in use. These batteries come in a wide variety of shapes and sizes. Compared to lead-acid batteries, Lithium batteries are lighter and provide a higher open circuit voltage, which allows for power transfer at lower currents. These batteries have the following characteristics:
● Lightweight, up to 80% less than a conventional, comparable energy storage lead-acid battery.
● Lasts 300-400% longer than lead-acid.
● Lower shelf discharge rate (2% vs. 5-8% /month).
● Drop-in replacement for your OEM battery.
● Expected 8-10 years of battery life.
● No explosive gasses during charging, no acid spills.
● Environmentally friendly, no lead or heavy metals.
● Safe to operate!
LiFePO4 batteries can be discharged up to 100% without risk of damage. Make sure you charge your battery immediately after discharge. We recommend discharging be limited to 80-90% depth of discharge (DOD) to avoid the BMS disconnecting the battery.
Lithium iron phosphate batteries can be charged in as fast as 1 hour. We recommend using a rate that charges our batteries in 2-5 hours. Please refer to the datasheet for your particular model, to find the recommended charge rates. All of our data sheets are available on our website within the product section.
Among all the environmental elements, temperature has the biggest effect on battery performance. The electrochemical reaction on the electrode/electrolyte interface is connected to the temperature. The electrode/electrolyte interface is considered the heart of the battery.
● If the temperature gets lower, the reaction rate of the electrode also gets lower.
● If the battery voltage keeps invariable, the discharge current becomes lower, and also the power output will be reduced.
● If the temperature goes up, the condition is reversed. That is, the battery’s power output will increase.
● The temperature will also affect the speed of the transmission of the electrolyte.
● If the temperature goes up, the speed of transmission will be faster.
● If the temperature goes down, the speed of transmission will be slower.
Will Nine lithium batteries are manufactured with the safest lithium chemistry, lithium iron phosphate (LiFePO4). LiFePO4 batteries are best known for their strong safety profile, the result of extremely stable chemistry. However, to make sure the batteries stay within their safety specifications and ensure they cannot be damaged, they have an internal battery management system (BMS). A BMS makes sure each cell in the battery remains within safe limits. A well-designed battery management system can help maximize lifetime, and ensure safe operation over a wide range of conditions.
6500 cycles 0.2C 25degree, 80%DOD, fully charge and discharge count 1 cycle
we suggest charge speed 0.2C and working temperature 25 degree to keep long life
Typically, LiFePO4 batteries are about a quarter of the weight of lead-acid batteries. What does this mean for your LiFePO4 battery applications? You aren’t weighed down by heavy lead-acid batteries, allowing your vehicles to run at a higher speed and with more efficiency.
LiFePO4 batteries are both durable and safe for use in vehicles from golf carts to yachts. Built-in safety features prevent your battery from overheating by shutting it down when temperatures rise too high. Most lead-acid batteries lack this mechanism, putting your battery at risk of catching fire.
LiFePO4 battery life is 10 times longer than that of a lead-acid alternative. Even when charging and draining LiFePO4 batteries once each day, LiFePO4 technology offers more than 15 years of life.
