2nd battery locations in a 90

Come on I know some of you guys had a second battery with a split charger, where have you managed to hide it?

Just in the stage of cleaning up my rusted battery seat box, added a nice isolator and now want to add a split charger with another battery..

Also kinda got addicted to hooking up some anderson plugs for the front and rear, and the smaller ones for things in the back like a fridge etc (plug and play!)

i was thinking the same for an 85AH AGM Leisure battery i took out my motorhome when i replaced it with a larger one. was thinking about putting it next to the starter battery if there is space and hooking up a split charge then running 12v to the back for lights, chargers etc. and also going to add a solar panel to the roof for proper offgrid.

Always fit a fuse to the power supply for the external anderson plugs, just in case some smart arse decides to short them out!

Yeah + they'll be on an isolator, fuse everything is the life lesson.

It depends what batteries you are thinking of fitting. A red and a yellow small Optima battery can fit in the battery box along with a decent (proper) split charge system and that combination will suit most needs

You can squeeze 2, 019 sized batteries in the original seat box.

You can fit two batteries in the seatbox.

Secured using 2 oem brackets

Personally never bothered with VSR relays as its just to run my fridge/derv heater both of which have their own cut offs.

Ran this way for 6 years without issue. I did however run an additional earth from the second battery to the chassis

i have two batteries in the battery tray in my 90. However, I don’t really need them so I’ll replace both with a single larger battery.

This is what i've gone with btw..

nice setup, is the tray for flattening out the floor in the battery compartment? cheers

It's pretty solid, it's from devon4x4, i googled the batteries and even watched a youtube video of the factory making them in the USA.. but yeah it depends on which battery tray you have also.. mine has a slant on one side so this fits perfectly.. and the dual setup.. deffo recommend this battery tray (they do both types, for slanted and straight)

Looks good. I’ve just bought a larger single battery to replace the old split charge and smaller pair of batteries in my 90 but I might consider what you have done longer term.

Take a look at this video if you ever decide to take a look at these batteries -

Will update you guys in a few days with my full wiring + split charger setup, got 2 relays to activate winch / anderson plugs also, so will showcase the battery box (ignore the rough black truck liner paint, its just my rough coat to go under the lining)
