This is the control box for my first rov. lots of wiring for those 4 little switches..
i cant decide if i should keep the battery in for mobility, or out for easy charging...
I would leave it in the box if it fits as it would be less bits to worry about and carry about, it's hard to tell from the pic but I would put a small power switch on it if it doesn't have one so not to flatten the battery if one off the switches is accidently operated in transit, its a pain in the you know what when that happens!!
