For 240 volts
through an inverter, connect the batteries in parallel: negative
to negative, positive to positive.
To increase capacity for 12 volts, connect the batteries in parallel:
negative to negative, positive to positive.
For 24 volt, 36 volt and 48 volt systems, connect in series: positive
- negative
Never mix
battery capacities, this will cause over charging on one battery
and insufficient charge on the other. A 100 amph should be connected
to 100 amph. If one battery is significantly older than the other,
it can pull the newer battery down as a result of lead sulphation.
