12v to 24v step up split charge relay

The connector was swapped for an xt90 cable as the original had an issue so it was sent to get repaired and swapped from the Anderson to xt90. The cable for the solar is 10awg which is 5.26mm2. Does that sound like a better size?

Yeah that'll be fine.

Just one other thing you'll need to be aware of using a split charge system, is that when the van stops charging the SB when it gets to 80%, it'll stop providing 13.3v+ volts and so the split charge will also stop, meaning you might find on a long drive that your power bank has stopped being charged. You might be able to get around this by turning on the headlights or something to force the alternator the charge the SB. That's the downside to a split charge, with a proper DC-DC charger it'll draw from the SB/alternator for as long as it needs to.

Ah ok, is there a way to stop that with a different system instead of a split charge?
