====== vandweller laws and corollaries ======


  * Those who tell you "want you want" don't know what you want and don't //care// what you want.
  * If your "deep cycle" battery doesn't have a published DoD vs. duty cycles data then it's not deep cycle.
  * If your "deep cycle" battery says "marine" on it then it's not deep cycle.
  * If your "deep cycle" has a CCA rating on it then it's probably not deep cycle.
  * Charging by solar alone is $$$ and difficult.  Charging by solar [[electrical:12v:alt_and_solar|and some other source]] is inexpensive and easy.
  * Framed poly panels are a good default choice.  Flex panels are expensive and rarely justified. 
  * for cheapest power, 2x 6v flooded > 2x 6v AGM > 12v AGM.  Lithium has about the same cost in the long run as flooded lead acid.
  * AGM benefits from forceful charging.
  * Lithium suffers from forceful charging
  * Most vandwellers have lead battery capacity in excess of their ability to charge it.  This kills batteries.
