BATTERY ISOLATOR

These solid state devices allow you to connect your
engine alternator directly to both batteries without fear
of overcharging or of one higher-charged battery
discharging into the other lower-charged battery. Using
this unique device, the batteries are electrically isolated
from each other. Both your batteries are always
automatically being charged whenever the engine is
running. For 6, 12, 24, 32 volt negative ground systems
