Lower Battery Cradle gets a Bottom

I am unhappy with the way the 3 battery packs fit into the motor/battery mount in the front as there is no support for the middle of the battery packs and they tend to sag a tiny bit (these three mount on their sides). I have bought a piece of 3mm thick aluminium sheet 300 x 600mm. Of course, when I tore the rubber off the lower mount (where the packs sit) half the black paint came off. I have to clean off the rest of the glue and repaint it - then I'll silicon the aluminium sheet into the bottom of the tray (sparingly - just to stop it moving).

The packs sag into those big gaping holes. I thought the packs would be strong enough but they are not.


I have cut the sheet to fit and hopefully tonight I'll cut the slots for the battery hold-down straps.
A bit of paint then fit it in - maybe tomorrow.
