AJMRTC 4S 100W Bidirectional PD Fast Charging Module, Intelligent Protocol Recognition Lithium Battery Charger Board with DC Port for 4Series Lithium Pack Power Supply Conversion

AJMRTC 4S bidirectional PD 100W fast charging module is a highperformance power conversion board tailored for 4series lithium battery packs. It supports bidirectional energy flow, realizing PD fastcharge input to charge lithium batteries and discharging outward via PD port meanwhile. The intelligent protocol recognition unit automatically identifies mainstream PD communication protocols to complete stable fastcharging negotiation. Besides PD interface, an independent DC port is reserved to expand more power access methods for diversified project requirements. Multiple safety protection mechanisms guard against overcharging, overdischarging, overcurrent and shortcircuit risks to protect lithium cells and peripheral equipment. Compact board layout fits custom power bank assembly, portable power station refit and various lithiumbatterybased DIY electronic projects. Please doublecheck battery series count and voltage parameters before wiring.
