The advanced technology in the DCVSR always ensures that the first battery is fully charged, before the connection is made to the second battery. This prevents problems that may result from your charging source being too low in amps to charge all batteries at once. If placed in linear sequence between each battery the DCVSR Dual battery isolator can provide proper charging for several batteries in multiple battery setups such as in larger boats that may have 2 or more house batteries.
  1. Easy 3 wire connection at the battery. No need to bypass existing alternator wiring.
  2. Dual battery isolator setup has no volt drop. Conventional diode isolators incur a minimum of 0.6-volt drop.
  3. Compact size – No large heat sink.
  4. Cost-effective solution.
  5. Dual Sensing.
  6. Lifetime flat fee replacement.
  7. Compact, durable and smarter.
  8. Anti-vibration and corrosive proof

*DCVSR Battery Isolator is programmed with a 60+- second delay before engaging or disengaging.

DCVSR battery isolators can be installed between batteries with a common ground to automatically control the charging process to the batteries but continue to provide isolation of them when a charging source is unavailable. The small size and rugged construction of these units allow for quick simple installation for even the most novice Driver.
