New Lithium Batteries by WECO
- WECO is a middle east based tech company that has recently unveiled a lithium battery solution that offers dual voltage without any hardware change. It can operate as low voltage when placed in parallel and serves as high voltage when placed in series.
The dual voltage is possible with the help of an embedded battery management system and a dual circuit. These operate with the need for an additional battery management unit. The batteries can be mounted in different configurations. Mainly they can be mounted against walls or placed in a stack configuration.
Advantages
The dual-voltage battery known as 5K3 Low Voltage (LV)/Hight Voltage (HV) is an advanced lithium module for industrial and home energy storage systems. It has the following advantages
- One product for both applications LV and HV.
- High capacity due to the expandable structure of the batteries.
- Wireless connectivity for real-time monitoring, remote intervention.
- Fast connection HV and LV.
- Ease of installation ( Stackable, Wall mounted, Floor mounted)
- Price in line with existing single voltage batteries
Structure of the batteries
The physical arrangement of batteries allows it to operate as both high voltage and low voltage,
Dimensions. The Three basic modules are interchangeable according to the need. These are
- LV and HV single module
- LV Stackable
- HV Stackable

Chemical composition of batteries
The lithium-ion batteries inside the 5k3 LV/HV module give the best performance and highest number of cycles ( greater than 7000 at 25 degree Celsius) due to WECO’s optimized chemical composition. Lithium-ion batteries use lithium iron phosphate (LiFePO4) as material for electrodes. The ambient operating range is between -20 to 45 degrees Celsius. Lithium-ion batteries use nanographene to improve the stability, duration, and performance of electrodes.
WECOs Expansion
WECO is currently operating a production line in China. It plans on expanding by activity the production line at their facility in Florence, Italy. Their first batch was sold across Europe in July of 2020, But from November 2020, the 5K3 HV/LV batteries made it’s way to the USA. WECO plans on expanding and continue delivering high-performance dua-voltage 5K3 batteries.
Comparison with batteries employed today
Using a dual voltage switchable battery, the opportunity cost of choosing a battery becomes zero. There is no need to compromise on High voltage or low voltage using 5k3 (LV/HV) batteries. The price of these batteries is in line with the single voltage batteries. Rather than choosing two batteries, the same battery can be used for both industrial and domestic purposes.
