AJMRTC 140W PD bidirectional fastcharging mobile power module is a multifunctional protection mainboard designed for homemade mobile power supplies. It supports bidirectional 140W PD fastcharging, which means the battery pack can be rapidly charged via PD input, and meanwhile output highpower PD energy to charge external compatible devices. The module supports 26S battery combinations and is compatible with both ternary lithium and lithium iron phosphate battery cells, giving you more choices for your DIY battery pack design. Builtin comprehensive safety protection mechanisms monitor voltage, current and temperature status in realtime, cutting off charge or discharge loop when abnormal conditions occur to protect battery cells and the module itself. Optimized power conversion circuit keeps high working efficiency and controls heat accumulation under highpower working status. With clearly marked pin headers, it is easy to connect battery packs and output interfaces. Ideal for assembling highpower homemade power banks, small portable power stations and lithiumbased backup power supplies. Please match correct seriescount battery packs and strictly distinguish between ternary lithium and lithium iron phosphate parameter settings to avoid equipment damage.
