Had no idea either that just to charge the thing I have to pull half the boat apart ? Wow ! what a total pain in the arse that will be each time
I'm tired, it's late so will have another look in the morning.
Sorry, I'm a plane and heli guy so this really is a learning curve.
She weighs a ton too. Almost as heavy as one of my kayaks!
