Hi, So I have got a domestic lithium battery. It is charged via solar and a B2B charger from the engine batteries.
When the engine is not running, I would like to keep the engine battery and bow thruster battery topped up by the solar once the lithium has been recharged.
Would it be possible to have another B2B charger going from the lithium to the lead acid and build in some kind of switch so that when the ignition is on, it activates one B2B charger and when off, the other is activated?
Any idea if this is possible and what type of switch I would need?
Hopefully that makes sense.
