LFP12.8-200

1.（Automotive Grade Lithium Battery）Junlee lithium iron batteries have exceptional quality since they are manufactured by Automotive Grade LiFePO4 cells with higher energy density, more stable performance & greater power. Hightest-level safety based on CE Testing Certificate for the cell inside the battery. With no acid in the battery, you're able to safety mount in any position. This makes li-iron batteries perfect for solar home, RV, Campers,Golf cart, motor homes, off-grid applications.

2.(10 Years lifetime)Junlee LiFePO4 battery provides 4000+ cycles, which is more than 10 times to lead acid with 200-500 cycles. Junlee LiFePO4 battery has a 10-year service life, three times longer than the lead acid's 3-year lifetime.

3.1/3 Lightweight Junlee LiFePO4 Battery weights only 1/3 the weight of lead-acid batteries, which makes it an easy choice for RVS,Marine and off-Grid applications when mounting or mobility is in the consideration.

4.95%*Efficiency Junlee LiFePO4 battery's flat discharge curve holds above 51.2V for up to 95% of its capacity usage, providing astronomical boosts in run-time compared to only 50% in lead acid. This product is your best choice for outdoor camping power and indoor easy installation.

5.100% Protection Junlee 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 high-tem cut off preventes charging over 167℉（75℃）. Without memory effect, no matter what state the battery is, it can be used as soon as it is charged. Junlee LiFePO4 battery is IP65 level waterproof, which set you free from worrying to install indoors or outdoors.

Lithium cells aging→Voltage and resistance pairing→Welding→BMS testing→BMS assemble→Semi-finished product testing→set case→Finished product shipment

Cell balancing: It is mainly to charge and discharge a single cell, test the capacity of the cell, and allocate cells with similar capacities together, so that the voltage consistency of the subsequent assembled batteries will be better, and the system will be more stable;

Voltage and resistance pairing: divide the capacity of the cells for voltage and internal resistance distribution, and only cells with the same voltage and internal resistance can form a group of batteries. If the subsequent charging and discharging are randomly assembled, the voltage of each cell of the battery may be inconsistent, so that the battery may be protected in advance during charging and discharging, which will affect the capacity of the battery pack;

Welding:The cells are welded in series and parallel to achieve the voltage and capacity required by customers. In the process of spot welding, it is necessary to ensure that the spot welding is firm, and the virtual welding of the spot welding will seriously affect the capacity and voltage consistency of the battery;

BMS testing: The main functions of the protection board include: overcharge protection, overcharge recovery, over-discharge protection, over-discharge recovery, over-discharge current protection, overcharge current protection, short circuit protection, and voltage equalization;

BMS install: After the BMS is tested, weld the cable or the bms battery pack in sequence, and the welding point is preferably centered, so that the collected voltage will be more accurate;

Semi-finished battery test: The main items of finished product test include: no-load voltage, load voltage, internal resistance, over-current protection, chargeability, short-circuit protection and other functions. After the test, we will analyze the load capacity of the battery, whether the battery can be protected when the current is too large or short-circuited, and whether the battery can be charged and discharged normally;

Semi-finished battery aging: battery aging is mainly to detect the capacity of the battery, and to detect whether the battery has a charge and discharge protection function. Through the detected battery capacity, it can be analyzed whether there is a virtual welding state and whether the protection board has advanced protection or no protection state. ;
