Why you should choose Lithium batteries over lead acid

  Compact size, light weight - roughly weighing 1/3rd to 1/10th of a lead acid in the same capacity)
  Ability to be drained down to close to 0% without affecting overall battery life and longevity.
  Standard lead acids will start to deteriorate when discharged below 50%. This means that a 10Ah Lithium is roughly equivalent to a 20Ah Lead Acid!
  Li cells don’t create any memory and can be topped up regardless of their current charge level.
  Lithium batteries hold their voltage much higher throughout their discharge cycle than lead acids and have a much higher cycle life.
