Rapido V68
I have a Rapido V68 with Nordelectrica shore charger, victron mppt and shunt with two banner 100amp batteries. Before I swap out the batteries with lithium, where can I find if I have a nordelectrica dc to dc charger? Under front seat? A photo would be appreciated if anyone has one.

I don't know where any B2B you might have is located, but there is a way to find out if you have a B2B. It requires taking a few voltage measurements at the battery terminals with a multimeter.

First disable or disconnect the solar controller to avoid confusion with the solar output. Measure the voltage of the starter and leisure batteries with the engine stopped. Then start the engine and measure the two battery voltages again. If they are different, then you have a B2B. If they are about the same, then you probably have a split charge relay. However it's possible that the voltages are the same by coincidence. Measure the voltages a few more times with the engine running, for example at the end of a good long drive. If they are always the same, then it looks like you have a split charge relay not a B2B. If they are ever different, then you have a B2B.
