Upower 12.8V/10Ah Battery Key Features

LiFePO4 technology and superior performance

This battery uses LiFePO4 technology, which is notable for its high energy density and much longer life.
It also offers excellent thermal and chemical stability, making it much safer than traditional lead-acid batteries.

Its compact monoblock construction groups the cells together to deliver its 10 Ah capacity at 12.8 V in a stable and optimal manner.
Thus, it provides constant and efficient power for low and medium power devices and systems.

The battery is designed to provide balanced and safe performance in both charging and discharging applications.
In addition, it provides a stable and efficient discharge throughout its life cycle, maintaining consistent voltage and reducing energy losses.

Integrated BMS

The Upower battery incorporates an integrated Battery Management System (BMS) that monitors and protects the battery against conditions that may affect its performance or safety.

The BMS is responsible for protecting the battery against overcharging and over-discharging, and balancing its cells to extend its life.
It also prevents short circuits, overcurrents and extreme temperatures. In addition, it improves overall usage efficiency.

This type of built-in protection is essential to ensure safe and reliable operation, especially when the battery is used in demanding systems.

In addition, the integrated BMS of this battery monitors the total voltage and temperature of the battery and of each individual cell.
It also monitors the state of charge (SOC), depth of discharge (DOD), state of health (SOH) and current in and out of the battery.

Thanks to this system, the battery operates within safe parameters without the need for additional maintenance.
This simplifies its use in domestic and professional applications.

Service life and durability

LiFePO4 batteries are known for their long cycle life. In particular, the UE-12Li10 has up to 2500 cycles at full charge.
This means that they can withstand thousands of charge and discharge cycles without significant loss of capacity.
Thus, they far outperform lead-acid batteries in terms of durability and sustained performance.

In addition, its continuous energy efficiency and low internal resistance help to keep more energy available during each usage cycle.

Temperature range and conditions of use

This Upower battery is designed to operate reliably over a wide temperature range, from 0 °C to 45 °C (charging) and from -20 °C to 60 °C (discharging).
Therefore, it can be used both indoors and outdoors.

This wide operating range, together with its robust and stable construction, makes the UE-12Li10 suitable for different climates and environmental conditions.

Design and construction

The Upower UE-12Li10 battery features a compact monoblock format, meaning that all cells are grouped together in a single, robust, ready-to-install package.
This facilitates installation in small spaces without the need for complex housing systems.

It also has compact dimensions and a light weight, making it an easy battery to handle.

Moreover, as it is a “sealed” and electronically managed battery, it is maintenance-free.

This format makes it ideal for both stationary and mobile configurations, combining ease of installation and handling with high energy density.

Flexibility and scalability

The battery can be connected in parallel or series with other units of the same model to increase capacity in parallel (Ah) or total voltage in series according to the specific needs of the installation, allowing up to 4 units (4×4).

Advantages of the Upower Lithium Battery 12,8V/10Ah - UE-12Li10
