The "BOM" lists a 35 Ah / 12 V battery, which is reasonable. A 420 Ah battery is (a) a boutique item (b) should weight around 120-140 kg (c) does not fit into a toolbox (d) costs significantly more than 299 $.

From a professional standpoint I'd nag about
> the battery is laid into the tool tray. Plenty of extra space in this toolbox, which protects the system from dust and the sun.
A closed box is not a good place to keep actively cooled electronics; less so when it's a black box in the sun.
- peterwwillis 9y agoYou can get passively cooled 150W inverters, but yeah, a black box outside in the desert may not be ideal. You can eliminate most of the radiant and some of the convective heating with a beach towel on the box and an umbrella+emergency blanket above it. (I mean, we are talking burning man, after all) If you seal your box in a humid environment, the cool night temps can cause condensation, so ventilation of the box would be useful to prevent this (as well as provide for active or passive cooling of electronics) or throw in some silica gel packs.
- VectorLock 9y agoThe box is mostly to prevent dust ingress which is arguably a bigger problem than heat or condensation on the playa.
