Easy install. Works well. Worth pointing out in general the Bluetooth for this range of products isn't the strongest. E.g sometimes can't get it from sitting in the cockpit. But that's a minor detail because it's not a hassle to go near it the charger and engine detection work really well

In most boats and vehicles with multiple batteries (e.g. starter battery, service battery, winch/bow thruster battery), the battery MINUS terminals are connected to each other and to the boat/vehicle ground. The common MINUS eases charging current distribution, but also provides a path for interference signals from one DC network to another. Galvanically isolated B2B devices are used on special boats/emergency vehicles to break ground loops and thus protect sensitive technical equipment from sources of interference.
