Earlier today, I almost bought a little Power Splitter and it was really quite expensive too. Then I got a grip of myself and realised that it made far more sense to just make a simple wire-splitter with Anderson PowerPole connectors.
The only reason I wanted one was for when I wanted to add an accessory to my LifePo battery while outdoors - perhaps a small ATU or a powered meter or maybe just something to put some charge into my phone for the hotspot. I didn’t need more than a single extra connection.
While I was doing it. I decided to do it properly and make sure it was fitted with easy-change fuses.
