140W Bidirectional Fast Charging Module USB-C to DC PD3.1 Charger & Discharger Compatible

Building a DIY battery pack or repairing a lithium system but tired of juggling separate chargers and dischargers? The 140W Bidirectional Fast Charging Module solves that in one compact board — charge your battery pack from any USB-C adapter, or power your devices directly from the pack, all through a single PD3.1-enabled port.

This module delivers up to 28V at 5A (140W peak), supporting bidirectional energy flow between USB-C and DC terminals. It is compatible with 2S to 6S lithium chemistries — Li-ion, LiFePO4, and Polymer — making it genuinely versatile for portable power stations, e-bike battery repair, solar storage projects, and custom power banks. With support for over 8 fast-charge protocols including PD3.1, QC 2.0/3.0/3.0+, AFC, FCP, SCP, and DRP Src, it negotiates the highest safe voltage with virtually any USB-C charger you already own, so you are not locked into proprietary accessories.

Safety is built into the silicon, not bolted on as an afterthought. Onboard temperature monitoring, overvoltage and undervoltage protection, and optimised thermal circuitry keep the module stable under continuous load. The ultra-compact 60×60mm footprint and 30g weight mean it fits inside almost any DIY enclosure without redesigning your build. An LED error indicator flags configuration issues instantly, saving hours of troubleshooting.
