AJMRTC 4S PD 100W bidirectional buckboost module is a highperformance lithium battery charge and discharge integrated power converter module, rated for maximum 20V 5A power capacity. It supports PD fast charging protocol and realizes bidirectional energy transmission, capable of completing stable stepup and stepdown voltage conversion.
This module works as both lithium battery charger and discharger. It can use PD power supply to charge 4S lithium battery pack, and also convert battery energy into stable output voltage to supply power for external loads. Multiple safety protection circuits are embedded on the board to prevent overvoltage, overcurrent, shortcircuit and reverse connection risks during chargedischarge circulation, protecting the module and connected lithium cells.
Compact board size makes it fit various DIY development demands. Widely applied in homemade portable power stations, lithium battery power transformation, laboratory power test, electronic equipment modification and other DIY electronic projects. Notice: correct wiring must be strictly followed. Users should possess basic electronic operation experience. Wrong connection will burn out the module and battery.
