Functions of LiFePO4 Battery
Self-heated Function
To relieve winter range anxiety in some freezing environment, the BMS can bring with self heating function. Resistance heating rapidly warms the inside of battery. Start heating temperature:≤0°C. Stop heating temperature:≥10°C. Can improve battery charge / discharge performance.
Bluetooth Function
LiFePO4 technology offers high-powered cell performance compatible with lots of lithium-ion application to deliver more power and extend long life. Also built with bluetooth function allow you to read battery status freely anytime.

Storage and Transportation of LiFePO4 Battery 12.8V 50Ah
· Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.
· During transportation,50% SOC must be kept to ensure that short circuit, appearance of liquid in the battery or immersion of battery in liquid never occur.
· Battery should be kept at -20℃～45℃ in warehouse where it’s dry, clean and well-ventilated.
· During loading of battery, attention must be paid against dropping, turning over and serious stacking.
Precautions
>-- If the battery leaks or smells, move it away from open fire. The battery should be used after fully charged in the first use.
>-- If the battery pack smells, fevers, is out of shape, color changes or any other abnormal phenomena which the battery can't be used, if the battery is being charged or used, please take it out of the charger or electrical equipment.
>-- If the battery leaks and the electrolyte get into the eye, do not rub eye. Instead, rinse eye with clean water, and seek medical attention immediately. *Temperature will influence discharge capacity, if the temperature exceeds standard environment temperature(25±5°℃), discharge capacity will reduce.
