I'm trying to get a decent size battery to go on my LR90. However the only space to put it is underneath the passenger seat next to the other battery.
And there is even less space at the back than the front, where the main battery is.
The max height of the battery can be 15cm and can be 30cm wide and 23cm long. That's the space of the box.
I'd rather not get a Gel Cell battery in there as they are quite low on capacity. Any suggestions for getting something to fit please?
