Connecting the Charger to the Battery Pack
Looking at the front of the charger, you will see that the lower DC output cable has a
gray SB-50 Anderson connector on it. This SB-50 is quite common on EV battery
chargers and we recommend that you leave this plug on the cord. The SB-50 connector
has clearly marked positive and negative sides. Measure the distance from your most
positive battery terminal to your PFC charger’s SB-50 connector. Cut a #6 AWG or
thicker cable to the appropriate length and solder or crimp the appropriate size SB-50
pin onto one end of the cable. It is recommended that you use bright orange cable with
a good insulation and voltage rating in excess of your fully charged pack voltage. (Bright
orange Carol brand Super Vu-Tron welding cable is an excellent solution.) Place red
heat shrink or red electrical tape around the cable near each end to clearly designate it
as the positive cable and then using a matching gray SB-50 connector, push the SB-50
pin end of the positive cable into the positive side of the SB-50 until it clicks and locks in
place.
Measure the distance from your most negative battery terminal to your PFC charger’s
SB-50 connector. Cut a #6 AWG or thicker cable to the appropriate length and solder or
crimp the appropriate size SB-50 pin onto one end of this cable. Place black heat shrink
or black electrical tape around the cable near each end to clearly designate it as the
negative cable and then push the SB-50 pin end of this negative cable into the negative
side of the SB-50 until it clicks and locks in place.
