I posted a photo of the two new 110Ah batteries located in the new battery area below the fridge previously, so the next job was to wire these up and remove the original leisure battery for fitting to Duncan’s Caddy conversion.

I opted for new sealed wet flooded lead acid batteries as the charger in the Sergeant controller is not configurable for other battery types. A future job is to replace this mains battery charger and install a Victron B2B charger at the same so I will then have the option of using other battery types. I tried to plan ahead for this as the Victron Smart Solar charger I fitted previously is also configurable for different battery types.

I’ve wired up the new lead acid batteries and fitted a 50A DC circuit breaker, and fused each lower rated supply individually running from this. I mounted the batteries on a board, strapped them to this for security, and added two small handles so I can pull the batteries out should I need to work on something. The board is also screwed in place for security.

I took the opportunity to shorten the wiring from the solar panel to the controller and tidy up some wiring that was messy. Completing this coincided with the sunniest day this year so far, so the performance from the solar panels was the best if I have experienced so far.
