Shared bicycle solar panel 6V5W 18650 charging PCB 4MOS automatic polarity conversion

Overview

Introduction: Solar single lithium battery charging board based on CN3791 MPPT and comes with automatic polarity conversion of lithium battery. There is no need to distinguish between positive and negative poles. It is very convenient to install at will.

The automatic polarity conversion using MOS tubes has the advantages of high voltage reduction, high efficiency and low loss, which is good news for low voltage and high current applications. The voltage drop of this module is only 0.13V at such a large current of 12V 10A. If you use an ordinary bridge stack, then With a voltage drop of 0.7V*2, the loss is 14W, while the loss of our module is only 1/10 of his 1.3W. In the past, your bridge stack under 10A current had to add a heat sink to work stably, but now our module is just a little warm. What are you waiting for, replace your bridge stack.
