Before you install anything: the (4) counter-sunk side of the mounting holes (that fasten the tray to the bottom of the motor mount blocks) should be facing down (opposite side of where the batteries and standoffs are) so that the flat head screws will seat properly when the battery assembly is connected to the motor mount and wheel assemblies.
Note: The physical size of the batteries (that are included in the Arlo Complete Robot System) may vary slightly due to battery manufacturing tolerances. Therefore, it may not be necessary or feasible to install the middle retention posts. If you choose not to install the central posts, there are other optional holes to install retention posts on the outsides of the battery tray (close to the terminals) which have been outlined in the above image with an orange box. Use the best configuration for your battery size and setup.
If you’re using the standard 12 V, 7.5 Ah sealed lead acid (SLA) batteries (that come with the Arlo Complete Robot System), the (included) 5/8” F/F standoffs and #4-40 x ½” long pan-head screws will hold them securely as shown. The staggered hole patterns accommodate slight dimensional variances between different brands of batteries. Use the (staggered) holes that provides for the tightest retention of each of the batteries.
This completes the installation of the batteries and the battery tray.
If you wish to mount a single 12 battery to the Arlo Platform instead, use the following Single-Battery Configuration shown here:
Complete battery tray installation by following the tray mounting-procedures as outlined in the double-battery configuration instructions, above.
