Battery box tie down was considered a little weak. The rules say that the batteries must not break free with up to 20 x gravity (weight of batteries)in a head on collision.
High tensile grade 8.8 x 12 mm bolts have been used to tie down the main battery box (at the front of the tray). The storage box (rear of the tray) has 2 batteries and the 144v charger, so high tensile grade 8.8 x 10 mm bolts were used. Also much bigger washers were used to prevent the box from tearing off the bolts.
