Come on Rick how do you really feel?
Rick makes some good points about battery failure, that is why I feel having two separate banks is a prudent safety feature.

It does not appear to show the proper time remaining even when initially charged and going forward, during use. He feels he cannot depend on it and if he did he may end up stranded at sea.
