Increasing Capacity with Parallel PHI Smart-Tech Battery Configurations
Special attention should be paid for parallel installations. Correct wiring is essential to insure optimum
performance and system longevity. All wire “runs” should utilize
identical wiring gauge and identical wire
lengths between PHI2.6™ Smart-Tech Batteries and the common negative or positive “Bus” or Load.
Figure 1.4
Figure 1.4 depicts one of four PHI2.6
TM
Smart-Tech Batteries that will have been wired in Parallel. The wiring
arrangement will be repeated to connect all four Smart-Tech Batteries in parallel. The completion of this
configuration will require
8 identical lengths of appropriately heavy gauge copper wire.
Alternate wiring schemes are also effective. The “Cross Diagonal” method is perhaps less common but
has been evaluated in outside facilities and found to be very effective. The Cross diagonal method can
minimize copper wire runs to a degree and can also serve as a tool in complex wiring schemes where
space is at a minimum or system layouts are complex or irregular. For more information on cross diagonal
wiring methods, and the benefit of correct wiring configurations, refer to:

Use identical length and gauge wire to balance the load across the batteries.
Helpful Tips:
• Determine the cable length for the battery terminal farthest from the bus.
• Make all Battery cables a matching length.
• Additional cabling or slack that remains with the shorter distance runs can be coiled
and secured with Zip Ties.
