I have 2 start batteries. Each engine and the generator has a 1-2-both-off switch, so any of the above can be started from either battery. Normally the port engine starts from battery 1, stbd and generator from battery 2. I've had no issues with this sharing arrangement. In my case, the house bank is separate and nothing can start from it without jumper cables (it only ties to the engine batteries via ignition-interlocked ACRs for charging with engines running).
