BUILT IN BATTERY MANAGEMENT SYSTEM

Flykol Lithium battery use a built-in Battery Management System (BMS) designed to automatically disconnect the charging or discharging circuits to prevent damage to the cells and internal electronics from abnormal operation and helps to ensure safe and accurate operation of the battery.

THE BMS PROTECTION FEATURES INCLUDE:

  • Low Voltage Protection Switch – Automatically disconnects the discharge circuit to prevent damage to the cells if the battery drains below a pre-set voltage.
  • Over Voltage Protection Switch – Automatically disconnects the charging circuit to prevent damage to the cells if the battery is being charged above a pre-set maximum voltage.
  • Short Circuit and Over Current Protection Switch – Automatically disconnects the discharge circuit if the load draws currents above pre-set limits.
  • Reverse Polarity Protection Switch – Automatically disconnects the charge and discharge circuits if a reverse polarity condition is detected.
  • Thermal protection – Built-in thermal sensors will automatically disconnect the charge and discharge circuits when excessive temperatures are detected.

CELL BALANCING

The BMS balances the cells through top-end balancing and will discharge cells that exceed 3.65V during charging.

INTERNAL CELL SAFETY

  • THERMAL FUSE: Our latest prismatic cell technology is manufactured with an internal thermal safety fuse between the anode and cathode that will break and disconnect in the unlikely event the cell would begin to overheat.
  • SAFETY VENT: Each cell has a high-pressure safety vent that will flip open to release energy and prevent explosion.
  • FLAME RETARDANT ELECTROLYTE: Our cells are manufactured with a flame retardant additive in our electrolyte.

Advantage:

【All-New Design, All-Round Safety】The lithium RV battery is wear-resistant and durable thanks to the newly adopted high-quality SPCC battery case, and we optimize the internal layout and construction. The battery also comes with a main switch to turn it on or off at the touch of a button. And there is a thermometer and hygrometer on the top to display the battery temperature and humidity in real time.

【Compact in Size Max on Power】12V 400Ah LiFePO4 RV battery is equivalent to the energy of 4 x 100Ah battery but took up only 1.1ft³ of space and is smaller than 4x100ah battery. And It will be easier to maintain and install without the need for excessive wires and money. It helps you save money and space.

【Upgraded 250A BMS and Low Temp Cutoff 】After years of research and testing, we have adopted grade A cells that are fitter for RV/camper use, giving the battery powerful and stable performance throughout every cycle. Make your journey trouble-free. And Low temp cutoff protection prevents battery damage in a low-temperature environment.

【Safety & ECO-Friendly】 The stable Lithium Iron Phosphate chemical structure makes the LiFePO4 battery not burn or explode even at high temperature, short circuit, impacts, and drop. Highest-level safety based on UL Testing Certificate for the cell inside the battery. And it does not contain any heavy metals or rare metals and is more environmentally friendly, which is called a green battery.

Wide Range of Application

Widely used in RV, camping car, marine,boat,golf carts,sightseeing cars,solar backup,solar pv light, industrial equipment, and other deep cycle replacement.

Frequently Asked Questions

How long does it take to charge 400Ah lithium battery?

Once this voltage is achieved, we can calculate our recharge rate by looking at the amps of our recharging current. If our battery have 400 amp/hours of energy when fully charged, it would take a 40 amp current around 10 hours to recharge them fully.

How long will a 12V 400Ah battery last?

“12V 400Ah LiFePO4 battery provides you 5.12kWh energy supply, last 12 days to keep you away from the power outage(ensure a daily electricity demand of 0.4kWh).”

What is the difference between 12V 400Ah and 24V 200Ah?

Well, they each contain the same amount of energy, as 12V∗400Ah=24V∗200Ah=4800Wh=4.8kWh . The voltage of the battery is different and therefore they’re not simply interchangable, as device are designed to operate off a certain voltage.
