Mechanical

  • Density. Getting as many batteries as possible in as small a footprint is a goal.
  • Physical Safety. Its got to be stable and hold lots of heavy batteries but not be able to fall over on top of a child who might be trying to climb on it to get his battery.
  • Stackable. More vertical space is available than floor sq footage so an idea was to make them stackable. But see above point.
  • Heat dissipation. Input stage power supply is about 85% (DC/DC may be higher). 2nd stage is 82%. So while on DC heat dissipation will be around 64 Watts and on AC around 98 Watts. (Calculated. Not yet measured)
  • Enclosure. Metal. Except perhaps for some plastic for the battery holder. Having metal available to heatsink to should help in keeping the electronics from burning up in hot countries.
