Looking for a IC chip that can monitor a 12 Vdc battery system
with lead-acid or gel-cel batteries. I have not had any luck search-
ing the web. I need to monitor a single and or a bank of batteries and
determine how much capacity is left in the system. I am not sure
if monitoring the voltage will provide an accurate value of capacity
left in the system. If I have 1 or say 4 batteries in parallel all being
450 CCA, would the voltage level being monitored represent the
capacity of the system ? All of the battery indicators I have looked
at seem to monitor voltage level to indicate battery level. What I=20
need to know is capacity remaining at the current AMP draw
rate.=20

In response to the current monitoring for 12 Vdc that has been=20
floating around I will be using a hall sensor from Honeywell

$20.25 from RS Electric for a 100 amp CT
