I have a van mount set-up and use a trolley system with pump and varistream attached to power it. The battery is housed on the trolley and is very time-consuming to remove. At present, I remove my trolley from van each evening and recharge the battery overnight in my shed (the terminals on battery are accessible without needing to remove battery from trolley). This is a big hassle, so I'm looking to run the system from my van's battery instead, but still going through the trolley. I know I can run a wire from my lighter socket and connect directly to my pump and varistream, but this would mean disconnecting my battery on the trolley, and re-connecting it every time I needed to use the trolley for those awkward cleans. My question is: Can I run a wire from the lighter socket and connect directly to my trolley battery terminals?
PS...I'm not interested in using one of those relay thingies as I don't do a lot of driving between jobs.
Thanks.
