iFePO4 Battery Deep Cycle 12v 120Ah LithiumBuilt-In BMS Protect Charging and Discharging

About this item:

[HOW TO CHARGE] The positive and negative poles on the battery can discharge and charge the battery.SCREAM POWER LiFePO4 battery’s flat discharge curve holds above 12V for up to 90% of its capacity usage providing astronomical boosts in run-time compared to only 50% in Lead Acid.

[Widely Applications] 50% lighter than lead acid battery of the same capacity, And there is no memory effect, no matter what state the battery is in, it can be used as soon as it is charged. Ideal for 12V deep cycle applications in Caravans, Camper Trailers, Medical Devices, Motorhomes & Electric Mobility Scooter.

[Built-In Smart BMS] Our LiFePO4 battery has built-in BMS (Battery Management System) to protect it from overcharge, over-discharge, over-current, and short circuit with excellent self-discharge rate. Built-in temperature protection function, BMS cuts off charging below -4℉(-20°C),high temp cut off prevents charging over 158℉(70℃).Battery BMS does not support battery series use.If you need to use it in series, please contact us for customization.

Safty performance:

No.	Items	Test Method and Condition	Criteria
1	Thermal exposure test	Each fully charged cell, stabilized at room temperature, is placed in a circulating air-convection oven. The oven temperature is raised at a rate of 5 °C/min ± 2 °C/min to a temperature of 130 °C ± 2 °C. The cell remains at this temperature for 10 min before the test is discontinued.	No fire, No explosion
2	Low pressure	Each fully charged cell is placed in a vacuum chamber, in an ambient temperature of 20~25℃. Once the chamber has been sealed, its internal pressure is gradually reduced to a pressure equal to or less than 11.6 kPa (this simulates an altitude of 15240 m) held at that value for 6 h.	No leakage, No fire, No explosion
3.	Short test	The fully charged battery is to be short-circuited by connecting the positive and negative terminals of the battery with resistance load not exceed 100mΩ. Tests are to be conducted at room temperature 20~25℃.	No fire, No explosion The Temperature of the Battery surface not exceeded than 150℃
4	Over Discharg	(After standard charge. Cells are discharged at constant Current of 0.2C to 2.0V, and the positive and negative terminal is connected by a 30Ω wire for 24 hours. Cell Condition: Fresh, Fully charged cell.)	No fire, No explosion
5	Over charge test	After standard charge, continue to charge with a constant voltage 4.8V per a cell, holding 8h.	No leakage, No fire, No explosion
6	Soak Test	Put the batteries into clean water, be soaked for 24 hours.	No break, No fire
