Battery cables from Spartan Power are flexible and easy to work with:
https://spartanpower.com/product/custom-battery-cables/. Many of SimpliPhi’s distributors also sell
battery cables. Refer to the SimpliPhi Wiring Guide for a list of distributors that sell cables.
•
Battery cables can be custom ordered to include the
3/8” lugs
that fit on the SimpliPHI Battery’s
threaded studs.
•
Determine the cable length for the SimpliPHI Battery terminal farthest from the common busbar or
plate first and use that length for all other batteries in the bank.
•
Additional cabling or slack that remains with the shorter distance runs can be coiled
and secured with Zip Ties.
•
Wire length should be kept as short as practical.
•
Positive wire runs should be separated from negative wire runs in separate conduit.
•
Energy supplied by the SimpliPHI Battery is reduced as electrical current moves through wire. For
lengths of battery cable greater than ~10 feet (3 meters), ensure that the voltage drop is no greater
than 3%.
•
To take full advantage of the combined SimpliPHI Battery bank’s surge rating, the DC busbars or
plates that the individual SimpliPHI Batteries are wired to should be rated to match the SimpliPHI
Battery bank’s total surge rating.

CAUTION:
Do not reverse polarity. Positive battery cables must connect to the SimpliPHI
Battery’s Positive terminal studs (RED) and to Positive DC busbars or plates. Negative battery
cables must connect to the SimpliPHI Battery’s Negative terminal studs (BLACK) and to
Negative DC busbars or plates. Reversing polarity will Violate the terms of the Warranty.
