1. General Information
01
LITHIUM IRON PHOSPHATE BATTERY
This specification defines the performance of rechargeable LiFePO4 battery pack UE-12Li300BL manufactured by
UPOWER, S.L., describes the type, performance, technical characteristics, warning and caution of the battery
pack. The battery pack support Bluetooth communication function. Through Android and IOS APP, can read the
battery status and information. Especially due to the Android system’s openness, different smart phone manufactu-
rer will have their own different Bluetooth hardware version and customized feature Android systems.
So the APP may not work well on some smart phones (with Android system) due to compatible issue.
It is necessary for the customer to confirm whether the phone is compatible for the APP.

5. Protective Circuit Specification
The batteries are supplied with a LiFePO4 Battery Management System (BMS) that can monitor and optimized
each single prismatic cell during charge & discharge, to protect the battery pack overcharge, over discharge,
short circuit. Overall, the BMS helps to ensure safe and accurate running.

following CC (0.33C)/CV (14.6V) mode to full capacity,
and then rest it for 1h. Repeat above process until full

7. Transportation
• Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be
created to protect the battery.
• Battery should be stayed in the warehouse 15ºC 〜35ºC where it’s dry, clean, shade and well-ventilated.
• The battery should be stored in 50% SOC during transportation.
• The battery need to be charged every 6 months if out of use.
• Keep the battery against dropping, turning over and serious stacking during loading.
8. Warning & Tips
Please read and follow the specification and caution remarks on battery surface before use the battery. Improper
use may cause heat, fire, rupture, damage or capacity deterioration of the battery. UPOWER, S.L.
describes is not responsible for any accidents caused by the usage without following our specification.
• The battery must be far away from heat source, high voltage, and avoid to be exposed in sunshine for long time.
• Never throw the battery into water.
• Do not put the battery in a charger or equipment with wrong terminals connected.
• Never connect the positive and negative of battery with metal.
• Avoid excessive physical shock or vibration. don't hit, fall, stamp on the battery.
• Without the permission of the manufacturer and guidance, forbidden to remove or to assemble the battery.
• Do not use the battery mixed with other different manufacturer, type, or model batteries.
• Keep the battery against high temperature. Otherwise it will cause battery heat, get into fire or lose some
function and reduce the life.
• When battery run out of power, please charge your battery timely (≤15 day).
• Please use the matched or suggested charger for this battery.
• If battery emit peculiar smell, heating, distortion or appear any abnormity during working or storage, please stop
using and take it out from device.

9. Battery Operation Instruction
9.1 Charge and discharge
9.1.1 Charging current:Do not surpass the largest charging current that specification stipulated.
9.1.2 Charging voltage:Do not surpass the highest limited voltage that specification stipulated.
9.1.3 Charging temperature:within temperature scope that specification stipulated.
9.1.4 Charge with constant current, then with the constant voltage, no reverse charge, which is dangerous.
9.1.5 Special note:
Short time doesn't affect the use of the battery overcharge too, but for a long period of time over
discharge or over charge can affect the function of the battery failure, or the battery can't use permanent,
appear serious safety hazards, need long time floating please use the recommended floating model
specification. Battery when not in use for a long time, because of its own self-discharge characteristics
can also cause discharge, to prevent the occurrence of a discharge, battery should maintain a certain
capacity, maintain the voltage at 50% state of SOC.
10. Other Chemical Reaction
Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a
long period of time without being used. In addition, if the various usage conditions such as charge, discharge,
ambient temperature, etc. are not maintained within the specified ranges, the life expectancy of the battery may
be shortened or the device in which the battery is used may be damaged by electrolyte leakage. If the discharge
time is much shorter than the normal after full charged, even battery is charged correctly, and this may indicate it is
time to change the battery.
