要約(日本語): The author had been used Li-MH batteries for wireless modules power since 2014,  but the life were far shorter than the nominal life. While JIS describes the capacity for continuous load only. Some wireless module dissipate 0.1 to 1A for transmitting, though the quasi static consumption are uA order. And so the author scratched a discharger generating repeated pulse load. The pulse height was regulated by FET and OP amplifier. The pulse width was controlled by MCU precisely. In general, discharger heat sink is big and its shipping fee is expensive. The author adopted aluminum squared pipe and sirocco fan that inflows air and doesn't diffuse air like axial fan. The author wired the circuit on universal boards and built boards, pipe and fan on MDF base which is easier for working.
