Product advantages--

  1. Open cooling system

Using heat sink anodic oxidation technology, the temperature can be radiated to the outside stably and safely.


  1. New MOS low internal resistance

Multiple optimized protection management schemes stably reduce the internal resistance of the circuit, increase the service life, and ensure safety and reliability.


  1. Brush with three-proof paint, multiple protections, to ensure safety and reliability.


  1. Smart chip, build an ideal life!

It is carefully made with high-quality components to achieve a series of functions such as high service life, strong endurance, and low charge and discharge temperature.


  1. The layout is clearly visible!

The inside to the outside of the protection board is intuitively visible, and each part can be clearly understood.
