I have a 2009 Yamaha Drive 48 Volt electric ( four 12 volt batteries ). I recently had the light kit ( headlites and tail lites ) installed , but instead of installing a voltage regulator, I am using alligator clips across one of the four batteries. I have installed leads long enough to switch batteries so I am not using the same battery all the time. My question : will this hurt my batteries ( extra load when lites are on ) , even though I switch from one battery to another ?
