Review on Red Quick Disconnect Battery Modular Power 🔌 Connectors - 120A Battery Connector for Quick Connect by Robert Hayes

This is SH type (SH-120) and NOT compatible with more common SB type like SB-120 even if the connectors are the same size. Make sure you get the correct connector for your device. I was able to change the connector by cutting off some plastic, but that's not a good solution. Note the flat bottom of the plug, not the rounded top. If a plastic part connects the plus and minus terminals and the plastic part has a small end bent up, it is type SH. The end facing up is at the end where the connector enters the mating connector and is about 1/8 inch thick.
