with 1 kHz AC internal resistance test instrument.
Criterion
Rest for 1 hour after fully charged, then discharge
with 0.33C current until the battery reaches the
discharge cutoff voltage. Repeat above process for
three times, if the discharge time is not less than 180
minutes, you can stop and define the Discharging
current*time value (Ah) as battery capacity.

Characteristics
At 25±5°C discharge the battery with the current of
0.33C to the cut-off voltage. Store the battery at
various temperatures for 2h and discharge the
battery with 0.33C to the cut-off voltage. Record the
ratio between discharging & charging capacity.

MAX discharge Current 50A
Discharge with the current of 0.5C until it can’t
discharge, and then rest it for 1h. Charge the battery
following CC (0.33C)/CV (14.6V) mode to full capacity,
and then rest it for 1h. Repeat above process until full
charged capacity is no more than 80% of normal
value. Accumulated times is defined as cycle life.

4. Circuit Protection
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.

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.
Warning!
• 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.
• Never connect the positive and negative of battery with metal.
• Never sheep or store battery together with metal.
• Never reverse two electrodes when use the battery.
• Never disassemble the battery without manufacturer's permission and guidance.
• Never knock, throw or trample the battery.
Tips!
• 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.
• If the battery leaks and get into the eyes or skin, do not wipe, instead, rinse it with clean water and see doctor
immediately.
• Please far away from children or pets.
• Do not put disuse battery into a fire or water.
• If user needs to parallel several battery packs, please charge them to full capacity with same type of matched
charger, and set it aside for 8 hours, professionals only. This battery pack supports application no more than
20 group parallel. If user needs to apply this product to more groups parallel, please reconfirm details with us.
• It is strictly prohibited any series between the battery packs. Any requirements on serials connection, please
contact UPOWER for details.
6. Storage & 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 -20ºC 〜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.
