Product advantages--

  1. Open cooling system

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

 

  1. High quality low internal resistance MOS tube

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

 

  1. The function of disconnection protection!

Any string of battery packs, zero cell voltage, and any cable disconnection can protect the battery from no output.

 

  1. Stable heat dissipation, balanced protection

Can be connected to weak current switch, built-in temperature control.

 

  1. GPS port can be installed, balanced protection.

Weak current switches can be installed, all of which are sufficient. Low temperature rise and fast heat dissipation.

 

  1. Smart chip!

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