Thanks for your input - all good points to consider, so I really should look at how the whole system will work - I guess the radar and chart-plotter dont need to run for 24 hours and i could put in more capacity (200 AH?) without a huge increase in cost. Don't know if i have space for another...

G - You have a good point - in order to convert to Lithium, what else did you change? I guess all I would need is a new charger and to ensure the alternator was correctly set up for the change. I have a couple of Dyno 85 AH to sell !

Radar - 24 hours - 17 watts AIS - 24 hours - 3 watts Chartplotter - 24 hours - 10 watts Occasionally (hopefully never) a back up bilge pump - 100 watts Auto Tiller (engine running) 1- 8 amps depending on the conditions Lighting and all the original systems are on the other house bank as...

I was thinking of a 200 AH battery - so lots of spare capacity if needed, with not that much more expense or space required. Thoughts?

All three systems will be 12 volt. Lithium will be for Radar, AIS, Chart-plotter, maybe a second display, but nothing heavy, so no more than 100 watt hours. I like the voltage controlled switching option. Thanks.

I would like to add a second isolated house bank of lithium to my existing Lead Acid - 1 starter, 2 battery house bank system. The new 200 AH lithium system would have its own distribution panel isolated from the old system. The new system would power essential electronics and navigation...
