What is Mini UPS？

Definition of UPS:

Unterbrechungsfreie Stromversorgung (also known as UPS) is the uninterrupted provision of backup AC power for electrical load equipment in the event of abnormal power grids (such as power failure, undervoltage, interference or surge (surge current)). Equipment for the normal operation of electrical appliances. Under normal circumstances, uninterruptible power supplies are used to maintain the uninterrupted operation of key commercial equipment or precision instruments such as computers (especially servers) or switches, to prevent computer data loss, telephone communication network interruption or loss of control of the instrument.

The price of Mini UPS:

Mini-UPS is a combination of multiple lithium cells in series and parallel, because if a single cell is a 12v lithium battery, the efficiency and life of the battery are not very good.

Mini-UPS price estimation formula

Single lithium battery cell price x (3.6~3.7V*n)*m (number of cells connected in parallel) + protection board price + shell price + auxiliary material price + labor price

Generally, the voltage of a single Lithiumbatterie cell is 3.6~3.7V, and its price will vary due to the different materials and processes used in the production of lithium battery manufacturers.

Mini UPS charger:

Der Mini-USV charger is a charger specially used to charge Lithiumbatterien. Lithium batteries have higher requirements for chargers and need protection circuits, so lithium battery chargers usually have higher control precision and can charge lithium batteries with constant current and voltage.

The lithium battery charger has over-voltage protection and temperature protection. The maximum charging time is limited to provide secondary protection for the Lithiumbatterie. The floating charging method of the lithium battery charger can maximize the battery capacity.

Mini UPS protection board:

Mini-UPS protection board, that is, a circuit board that plays a protective role. It is mainly composed of electronic circuits, which can accurately monitor the voltage of the cell and the current of the charging and discharging circuit at all times, and control the on and off of the current circuit in time.

The protection board can play the role of charging and discharging protection for the series and parallel battery packs, and at the same time can detect the overvoltage, overcurrent, overtemperature, undervoltage, and short circuit status of each single battery in the Akku, prolong the battery life and avoid battery problems. Damaged by over-discharge. The protection board is an indispensable part of Mini-UPS.

Precautions for the use of Mini UPS

1.Mini-UPS should be kept at 50%-60% state of charge when stored for a long time and should be 2.recharged every 3 months, and charged and discharged every six months.

3.In the process of transportation, you should pay attention to moisture, moisture, and avoid squeezing, collision, etc., to avoid damage to the mini ups.

4.It is forbidden to use or place mini ups under high temperature (in the hot sun or in a very hot car), otherwise it may cause the Batterie to overheat, catch fire or function failure, and shorten the life.

5.It is forbidden to store it in places with strong static electricity and strong magnetic fields, otherwise the battery safety protection device will be easily damaged and will bring hidden dangers of insecurity.

6.If the mini ups emits peculiar smell, heat, discoloration, deformation, or any abnormality occurs during use, storage, and charging, immediately remove the Mini-UPS from the device or charger and stop using it.

Mini UPS type:

Note for charging Mini ups:

1.Charge in strict accordance with standard time and procedures.

2.Turn the switch to ON when charging, and check the status of the indicator light to see if the charging is effective.

3.Use the original charger, the original charger has strong supporting performance and moderate charging rate.

What should I do if the Mini UPS cannot be charged?

1.Whether the output parameters of the charger are normal, voltage, current, etc.;

2.Whether the charger circuit is normal and whether the connector is disconnected;

3.Whether the lithium battery is broken, you can test whether the open circuit voltage of the battery is normal.
