I stupidly left some switches on for a few weeks which have drained my batteries. I left the switch on that joins the house and engine battery so both drained. I've bought a 1500amp Noco Jump start power bank.
My engine is a Yanmar 2YM15.
Both batteries when leaving the boat over the weekend were reading about 11.31V.
To jump start the engine, should I isolate to just the engine battery by removing the wires that link the batteries or would it be safe to jump start as is?
Thanks
