I was thinking of using these new splitters with the power injection ones that Ray offers; http://www.aliexpress.com/store/product/3-core-T-type-waterproof-splitter-the-middle-is-2core-BLACK-color-the-male-connect-s/701799_1707253215.html I see the injection connectors are the 13.5mm variant with 3 x 0.75mm2 cable. I assume that the 15mm connectors have larger pins and therefore can carry more current. So it might be better to ask Ray if he can make both types of connectors in the larger format. I am just starting out using these connectors and just wondering what people have had experience with? Which ones are better?
