The battery I use for my electric outboard has Bluetooth facility which allows me to monitor its discharge via my smart phone - which is vital when out on the water. The question I have is if I hooked up a second battery alongside it which does not have Bluetooth facility, will my smart phone monitor them as a pair or just as a single. No point I’m thinking of buying another Bluetooth battery which are more expensive of course if by hooking them up I can monitor the pair in situ.
