T6.1 Beach leisure battery extra 12V socket wiring

[petr_io]

I have a T6.1 Beach Tour with a leisure battery under the driver seat (left seat).

I have recently bought a large Ecoflow that I would like to charge from the leisure battery circuit, I am however not comfortable to run even 8A over long periods of time through the cigarette lighter sockets.

I am therefore planning to fit another socket with a proper thick wire going to it. I have already purchased the cable, a spurtar plug and socket combo and inline 30A fuses with a holder.

Next step is the installation - where do I connect it all up to? I would like to not break the battery current readout that is present on the camping control panel which I imagine will be bypassed if just wired it to the battery terminals.

I'd not use the traditional 12v connectors, use either the Anderson SB50 or the PowerPole series.

If you have a solar input on the EcoFlow you might be able to use that for the input and get higher current charging.

If the leisure battery is monitored then it will have a shunt on the negative terminal the same as the starter - so long as you don't wire direct to the negative terminal any load you take will be monitored.

On the standard second battery the on battery terminal holder fuse box often has a couple of spare high current ways, maybe use of those and wire the negative to the underseat earth bolt?

Thank you, that is super helpful!


I've got this one for the connector https://www.amazon.es/gp/aw/d/B07C6GD5K9?psc=1&ref=ppx_pop_mob_b_asin_title

Will check out the positive terminal wiring to see if there are any spares, that would be helpful!

One more silly question, what is the "proper" way to attach to a wire to a bolt? Do I need to get the metal o-ring with the cable crimp attached to it?

You should be using crimp connectors, this isn't the sort of situation you want to have any stray wires.

If you do find a spare way on the fuse box you might need to put a smaller fuse in suitable for the cable you use.

That connector looks exactly the same as the Anderson connector so you should be all good there.

I'd use 10mm2 cable on that, or at the very least 6mm². The connector is good for 50a and it's always good to have the overhead - the minimum cable it'll take is 6mm² anyway.

Connectors: If you use 6mm² then you can use the yellow insulated ring terminals

Ring Terminals - 3.0 - 6.0mm² Cable (Yellow)

High quality yellow pre-insulated ring crimp terminals (3.0-6.0mm² cable). 4.3/5.3/6.4/8.4/10.5 hole dia. Tinned copper conductor & PVC insulation.

If you use 10mm² then you'll need to use bigger uninsulated terminals, plus some adhesive heatshrink.

Copper Tube Terminals - 10mm² Cable

Closed copper tube terminal for 10mm² max. cable. Bell-mouthed entry & inspection hole. Can be crimped or soldered. Available with 5/6/8/10/12mm holes.

You can also use these on 6mm² cable.
