Seplos V3 16S 48V 280AH/314AH DIY Battery kits, BMS included, support communication with inverters for RS 485 and CAN.For a DIY users, only need to buy 16pcs battery cells+ this kits, time saving and convenient.

Most kits adopt a plug-in design that does not require soldering. Ordinary people can assemble them within 1-4 hours according to the video or instructions.

The time saved for searching, comparing, communicating, and reworking is itself a huge hidden wealth.

 

The BMS integrated into the kit is the "brain" of the battery, providing comprehensive protection such as overcharging, overdischarging, short circuit, overcurrent, and temperature control.

2A active balancing is crucial for battery consistency and long-term use

 

The dedicated battery box can provide mechanical protection against earthquakes and impacts, and ensure effective heat dissipation through fixtures or thermal conductive adhesive to prevent danger caused by overheating.

 

The case supplies external mechanical pressure

• Resistance to vibration and impact

Continuous vibration is generated during the operation of vehicles/equipment, and fixed structures (end plates, brackets, straps) are used to prevent battery cell displacement, collision, resulting in shell rupture or pole loosening.

• Inhibit the cumulative effect of inflation

Although the expansion of individual cells is small, the slight expansion and superposition of hundreds of cells after grouping may squeeze the box. The fixing system can disperse stress and avoid deformation of the box.

• Ensure consistent heat dissipation

By using fixtures or thermal conductive structural adhesives, the large surface of the battery cell is tightly adhered to the cooling plate, improving thermal management efficiency (insufficient heat dissipation can lead to uncontrolled heating).

• Maintain the reliability of electrical connections

Prevent the pole from loosening due to vibration and avoid local overheating caused by virtual connection of connecting pieces.

Suitable for home energy storage, 48V 15-18KWh Off Grid&Hybird Grid System.

During the day, batteries store solar energy or store Grid electricity when it is cheaper, and use the battery's power at night and during peak hours.
