• Intuitive four LED "gas gauge" gives an instant indication of battery type (cell count) and charge level.
• When used in conjunction with a "missing pulse detector" failsafe device (ADF recommended) the LiPo Guard helps
  protect your batteries from damage due to over-discharge. Low battery warning is indicated by a forced surfacing after
  which you will not be able to dive. If you're stuck on the surface, it’s time to come back for a recharge
• No setup required. LiPo Guard automatically configures for two cell (2S) and three cell (3S) Lithium Polymer and
  Lithium Ion batteries. Low voltage warning is indicated by triggering your ballast failsafe.
