Pros
- Cheapest way here to add alternator charging to a single house battery
- Works with smart alternators using the included ignition wire
- Lithium, AGM, gel and flooded profiles cover most house batteries
Cons
- No solar input, so a roof panel needs its own controller
- Phone monitoring costs extra for the BT-2 module
- Not waterproof, so it must live inside the cabin
