Review on AIRIC 110Pcs Wire Ferrule Connectors Kit: 2/0-4 Gauge Premium Copper Terminals For Non Insulated Cord End Crimps 4 2 1/0 2/0 AWG by Andrew Sticher

Summary: Using this for the input/output cables on a Solar/PV charge controller. Previously, just tinning the wire to prevent fraying, but this is a better solution. Added the AIRIC ferrule connectors to the ends of the wire. The black/white controller shows the BEFORE tinned only wires.Pros: Good fit & finish; good assortment.Cons: None.Conclusion: At $21, rating this 5-stars. Very impressed with the entire iWiss line of hand tools.Related Products:IWISS Square Self-Adjusting Plier for AWG23-10 End-Sleeves Ferrule $21https://www.amazon.com/dp/B00ODSJGSW
