Hi LNC4 guys!

Here is a question from oversee. I have never seen any LNC4 with an external electric power connection. When battery goes dead after fruitless trails to start the engine - what do yo do? Really a heavy job to dismantle the cowlings just to replace or recharge the battery. Has anybody installed an external socket to be conncected with cables from the car? How did you do it? Thanks for any advice and picture!
