Midziyo yekuchengetedza iripo yenguva pfupi yemagetsi spikes, asi kushanda kwakasimba pamusoro peyakayerwa voltage kunoshatisa hupenyu hwemidziyo kana kukonzera kutadza kukuru. Kune mabhatiri, kupfuura yakakwira voltage inogona kukonzeresa kutiza kwemafuta, kunyanya mu lithium chemistries.

Edza iyo inobuda voltage ine multimeter pasi pemutoro. Izvi zvinokupa iyo yakavhurika yedunhu voltage, iyo ichave yakakwira zvishoma pane yezita. Mazhinji emagetsi emagetsi eDC anobuda 5-15% pamusoro peyero yavo yezita pasina mutoro, achidonha kune zita remagetsi pasi peyakayerwa mutoro. Chinhu chisina kunyorwa chinoverenga 13.8V chinogona kunge chine 12V zita reti, nepo imwe yekuverenga 29V ingangoita 24V zita.
