Thread: 2nd battery - under drivers seat? (Defender)

it’s not good practice to winch with engine not running.

Under driver seat needs pretty big mods if you want to fit a full size starter or AGM......have a look and you’ll soon see the difference between passenger and drivers.

I found two batteries under the passenger a pain, relocated the AUX elsewhere.

elsewhere where?

In the tub
In the cavity behind the rear wheel

I had two N70ZZ's under the passenger seat without moving anything.
There is a strip of timber to level the floor because from memory there is a step in it.

Came like this when I purchased 20 years ago, replaced the batteries then next time around I fitted a smaller deep cycle battery alongside the N70ZZ starter.
You do have to watch the terminal post at the front doesn't contact the lid when you re-fit it ! The smaller deep cycles have a flush post (if that makes sense) so no problem.

I'll take a photo when I get a chance but there's no room for a 2nd battery under with passenger seat the way all teh electric stuff is fitted.

@W&KO in the tube was the other place that I was thinking about, especially as that's where I intend to put my compressor so could wire that direct to that battery I suppose.

My concern was with the length of cabling required to battery and back and whether that would be a significant issue - I guess its not really THAT far though. Where did you run the cable?

Vlad, in this instance you Sir are a perfect candidate for a LiFePo4 battery.

Speak to Drivesafe (Tim), it will do everything you want and you can get big capacity under that seat in LiPo!
