Part #: 69-710TBVSR70A

The Trolling Bank VSR (TBVSR) allows charging of 24V DC trolling motor battery banks from 12 V DC systems. When the engine is started and the start battery reaches 13.7 V DC, the TBVSR cuts in, charging Trolling battery (A) for one minute, then Trolling battery (B) for one minute. This continues as long as the engine is running and the voltage is over 12.8 V DC. When the boat has reached the fishing spot and the engine is switched off, the battery voltage will drop below 12.8 V DC—at this time the TBVSR cuts out and stays disengaged.
