    I went over many years and build my own battery box.
    Using a NL solenoid under the bonnet.
    Currently on version #3 for the last 6/7 years.

    Used standard solar controller with a permanently mounted 100 Watt solar panel on the canopy.

    Red BH for Alternator
    Blue BH solar input
    Grey BH load.
    2 x USB
    1 x cigarette
    1 x Hella
    Added a 15 Amp fuse to the front for above outputs (was inside and a slep to get to) excluding the BHs
    30 Amp breaker to kill all power (50 Amp fuse between breaker and pos terminal).

    Cost less than R1000 over the last 25 years excluding the batteries (now on 4th one)

    I recently made the giant leap to Lithium in our Imagine Comfortvan:
    Previously, I replaced the solenoid in the older NL grey battery box with a Ctek D250s Dual DD - DC charger. It contains a 100Ah lead crystal battery. I also fitted a BH input from the solar panel on the roof rack, recently upgraded from a 120- to 200W. Next to the battery box in the Patrol is a 40l NL fridge. From the BH outlet on the battery box, I had wires going to a Ctek D250s in the caravan charging the 2 lead crystals.
    But then both batteries in the caravan packed up in spite of trying many times to revive them with the recondition setting on a Ctek charger. I then decided to go Lithium with the Blue Nova BN13v-108-1.4k. I sourced a MCdP Mk6 20A Power Panel from Manie du Preez and fitted it into the wall of the bench in the caravan. It has a switch for charging a LiFeSO4 battery and receives input from 220V, the battery in the Patrol and has a solar input. It distributes power to a double door 76l NL fridge, lights and pumps. I tested the LiFeSO4 last week and it kept the fridge going for a week with only the solar panel charging. The Ctek D250s is now obsolete because it can only charge lead acid batteries. The lead crystal battery in the Patrol is still going strong.
    Pics to follow.

    Below is my response to basically the same thread found here: https://www.4x4community.co.za/forum...t=#post4325489

    And is it R1k more now??

    This is seriously overpriced.
    4x4 Direct prices:
    NL battery box R2,200
    WRND DC-DC charger with MTTP solar regulator R2,050
    Total R4,250 vs R8,999 for the same functionality.

    Just a question: Is going from the BH outlet on the NL to charge the battery in the caravan the most optimal wiring option? Does the second battery in the vehicle charge first and then overflows to the one in the caravan or are the 2 batteries just connected in parallel?

    Look, it's not a thing of great beauty but it works for me.
    It's basically a long box with a battery compartment and a small storage compartment.
    Feed from the solar panels (2x45w) comes into the solar charge controller and then into the battery. I have a Brad Harrison and a cig lighter coming directly off the battery.
    There is a bat monitor below the charge controller.
    I have an extension lead to take power to the Caravan when we are parked.
    Everything is fused.
    It stays in semi permantly but the whole system (Inc the Solar panels) could be removed in 5min or less.
    You could certainly neaten it up but for me, it works 100%
