Guidance for dual battery install

skiwpk · Nov 9, 2022

Looking for the best threads or resources out there for a second battery install for my 2011 HSE. Ideally I’m looking for a simple setup for camping that allows me to manually switch from starter to house battery when parking for the night, then charges both batteries during the day when driving. Mostly looking to power audio and lighting, maybe a fridge in summer, maybe electric blankets in winter. Thanks - I’m new to the LR4, still transitioning from my 100-series LC.

a company out of Australia, Traxide, make kits. They require a little modification to work in US-spec cars due to our V8 configuration taking up more under-hood space, but folks here have made them work. It's on my list, eventually.

This. Just searching for "traxide" will give you a lot of good threads.

OP, keep in mind that a dual battery install on a 2014-16 LR4 is way more involved than it would be on your 2011. Michael Gain did the hero's work on a dual battery install on his, but thankfully a lot of his headaches won't be yours.

Creating the wiring is easy, I’ll share what I used on my FJ80.

My question: on a 5.0 powered LR4 where do you put the aux battery? It’s tight in there!

I installed the Traxide D3-BU kit. The main thing is clearing out space in the second battery tray - driver's side; to do this you need to move the ECU. The dust cover can be modified so you can keep the ECU covered - I don't think the instructions for that is in one of the websites below, but I'll keep looking.

Here's a photo of my second battery.

I saved the urls for some of the forum posts I looked at. The first three is a good 3-part write up that will walk you through it. The others have info too.

Here's a 3 part instruction:

LR4 Second Battery Install

Hello everyone! Guess this can by my introduction to the board. :) I've been a long time LR and RR owner and have recently purchased a 2012 LR4. My previous LR was a 2008 LR3 and it was a great vehicle. So, getting to the point of the thread I was a little bummed to find that LR had filled...

Traxide dual battery kit on LR4

Last weekend I installed a Traxide dual battery kit on my 2013 LR4. The kit is identical to the one many have already installed on their LR3, the only hiccup on the LR4 is that the auxiliary battery tray in the engine bay is presently "occupied" by a large plastic box containing the transfer...
