Beginning with the largest components, we created a safe space for the battery pack(s). The crate is powered by five 2S-5000mAh LiPo battery packs daisy-chained to create one 10S (36V) LiPo pack. We opted for the smaller packs because they were cheaper and easier to recharge (using five battery chargers at once makes this process reasonably fast) and damaging one or two cells doesn' | Beginning with the largest components, we created a safe space for the battery pack(s).

The harness for our daisy-chain is a row of XT-60 sockets mounted to the chassis ending in a XT-90 anti-spark plug. (The anti-spark plug has two contact points, the one you would reach first when plugging it in has an internal resistor to limit the current. This is helpful when connecting the battery pack to the VESCs as their capacitor-bays act like a short-circuit when empty, which would normally cause a large spark and contact corrosion. Once the plug is fully inserted, the second contact points provides the normal characteristics of the XT-90 plug.) | The harness for our daisy-chain is a row of XT-60 sockets mounted to the chassis ending in a XT-90 anti-spark plug.
