CHARGING / MAINTAINING MULTIPLE BATTERIES
To properly charge or maintain multiple batteries they should all be the same
type (flooded or AGM) and condition. It is OK to mix deep cycle and starter.
Charge each battery individually before connecting together.
Never connect
batteries at different states of charge. The charged battery will rapidly transfer
energy to the discharged battery possibly causing catastrophic failure.
Once the batteries are charged, use 18 gauge or heavier wire to connect the
batteries.
If connecting multiple batteries of the same voltage, wire them in parallel
(BatteryMINDer positive to positive A to positive B, BatteryMINDer negative to
negative A to negative B). This is the same type of connection you would use
when jumping a car (in fact, jumper cables are great for this).
If connecting 2 batteries of half your unit’s voltage (example: 6V batteries on a
12V unit), wire them in series (BatteryMINDer positive to positive A, negative A
to positive B, negative B to BatteryMINDer negative). When wired in series they
act as one large system at the combined
voltage (example: 6V+ 6V = 12V). You
can connect these systems in a series
parallel configuration in order to charge
or maintain 4 or batteries in groups of 2.
As long as your batteries stay wired
together they act as one large battery
allowing you to charge and discharge
them as a group
