How Lead-Acid Batteries Work
How does the electrolyte in a lead-acid battery work? The electrolyte in a lead-acid battery is sulfuric acid, which acts as a conductor for the flow of electrons between the lead plates. When the battery is charged, the sulfuric acid reacts with the lead plates to form lead sulfate and water. When the battery is discharged, the lead sulfate
How Does Lead-Acid Batteries Work?
When a lead-acid battery is in use, it undergoes a discharge process. During this process, the lead-acid battery releases electrical energy as its chemical energy is converted. The discharge process can be described as follows: The sulfuric acid in the electrolyte combines with the lead dioxide on the positive plate to form lead sulfate and water.

6 Frequently Asked Questions about “Does the thruster use lead-acid batteries ”
How much lead acid should I use for a bow thruster?
1) Keep lead acid for bow thruster. Its there, wired and working... no real advantage to making any changes. 2) The ACR is fine for that, between the start battery and thruster battery. Really you are just topping off your start battery and bow thruster battery. They shouldn't be drained all that much. 3) 30 amp Orion is fine.
How far apart is a bow thruster battery?
The House, Bow Thruster and Start batteries are all within 5 feet or less of each other. The Bow Thruster is about 15 feet from it's battery. Thank you all for validating my concern of the Bow Thruster's heigh current draw on LFP's. I will continue to keep the Bow Thruster on its' own its' dedicated 904D FLA battery.

The Bow Thruster (Lewmar 140TT 3hp) is Rarely maybe once a week and when it is used it's for less than 30 seconds or a minute at most. The Bow Truster is a Lewmar 140TT 3hp 12V motor rated 280 Amps on the cable size diagram. 3.
How do I connect my alternator & thruster battery?
The alternator should go to a switch and then the start battery and connect to the house via the Orion. There should not be a combine option on a switch for those two any more. You could rewire your current combine switch to the engine and thruster battery for a backup.
How much power does a bow thruster use?
The answer to this question depends on the size of your motor and the voltage it's operating at. In general, a 12V bow thruster with a thrust of 132lb will typically draw about 250 amps. Conversely, a bow thruster with 176lb of thrust will need a fuse of at least 355 amps. As the thrust (and horsepower) increases, so do your energy needs.
