The devil is definitely in the details. I got a mount for my house batteries made and installed under the fore bench for the dinette, and got them to the same voltage and made into one via parallel connection. Kilovault recommends commissioning them by fully charging them prior to install, but I don't have a proper charger, so I used my bench power on their recommended charging voltage to match the voltage at 10 amps on both of the batteries before I connected them. Once they were matched voltage-wise connecting them in parallel was uneventful. For now I am going to leave them like that since they are going to be sitting for a bit (they are at 35% SOC). I have been steadily working towards having the whole power system integrated and installed, but it takes a lot of 'take this step' and then order the piece for the next step, scratch head, repeat. Now I am moving on to the power bus bar under the console and integrating the inverter/charger and dc-dc battery charger. I think I have a pretty good idea of how it's all going to go together with the exception of how to wire the shore power, which I may bug my electrician neighbor to help me.
Also been making progress on the shelving and whatnot in the cockpit, I think what I intend to do will turn out useful.
