Product Overview

Let's start off with this crazy acronym VSBDC:

Variable Speed Boat Diving Compressor

An alternative to our floating systems, Brownie's has designed a Built-in-Boat Diving Compressor that is powered by (2) PC925 12V Odyssey AGM batteries AND will connects to your own boats batteries to continuously charge and operate while your vessel is powered up.

  • ​Why Use ODYSSEY BatteriesUp to 4-year limited full replacement warranty — not pro rated.
  • Longer service life
  • 3-10 years of service life to save you time, money, and aggravation
  • Longer cycle life
  • 70% longer cycle life than conventional deep cycle batteries — high stable voltage for longer periods of time.
  • Longer shelf life
  • Can be stored on open circuit (nothing connected to the terminals) without recharging for up to 2 years or 12.00V, whichever occurs first.
  • Faster recharge
  • The highest recharge efficiency of any sealed lead battery on the market — capable of 100% recharge in 4-6 hours.
  • Mounting flexibility
  • Non spill-able design — can be mounted on any side in any position except inverted.
  • Vibration resistance
  • Design protects against high impact shock and mechanical vibration — a common cause of premature battery failure.
  • Extreme temperature tolerant
  • Operating temperatures from -40°C (-40°F) to 45°C (113ºF), for models without a metal jacket, and from -40ºC (-40ºF) to 80ºC (176ºF) for models with a metal jacket.
  • Totally maintenance free
  • No need to add water, ever! Dry-cell design with resealable venting system.
  • Improved safety
  • US Department of Transportation classified as a ‘non spill-able’ battery. No acid spills, no escaping gases.
