Deep Cycle Or Starting Battery For Bow Thruster

7x120ah deep cycle for the house bank, 2x100ah starting battery pairs each for bow and stern thruster, and a single 180ah engine start battery. But first, a bigger picture.

We are testing this stunning Fairline Targa 50GT for its

This raises a couple of issues.

Deep cycle or starting battery for bow thruster. This does not happen with the port engine. Standard fla/sla batteries do better, agms even better still. The op has a 28ft boat, adding a bow thruster plus 56kg of batteries right at the sharp end would be a noticeable, i'd say.

2 for bow thruster, 2 for stern thruster and one for each engine. Parallel the 2 x 85 ah deep cycle batteries and use as the house bank (switch position 2), buy and fit a proper starting battery with some serious cca to use for starting and also to help deliver some decent power to the bow thruster as i don't think the deep cycle batteries can deliver the power in quick short bursts. There are two house battery banks with three paralleled batteries in each, each bank is rated at 1010 cca.

The boat currently has 12 agms aboard: Can lithium ion batteries be used to power a bow or stern thruster? Sorry to be late on this thread, but the bow thruster must be on the starter battery, unless it has its own battery on a separate circuit with a charge splitter.

Battery capacity and age under normal circumstances with new and fully charged batteries, you can expect around 50 thruster cycles before the battery must be recharged. I think) for the lead acid starting batteries. It is advisable to recharge batteries after each use if possible, to extend the life of the battery.

There is no limit to the capacity you can use and many bowthruster do use 2 x 110 ah batteries although for a 4hp motor one would probably be ok. As a rough guide, a light to medium duty battery will be good for about 200 to 300 cycles, while a heavy duty battery should easily be able double that amount of. Batteries fall into one of two categories, deep cycle or starting.

I was originally thinking of running the stern thruster off of one bank and the bow thruster off of the other bank but the side power thrusters. Deep cycle batteries are great for domestic banks, not so good for engine starting, winches or bow thrusters. Second, bow pro thrusters use a brushless induction motor, a feature that shortens the list of maintenance chores.

You select the program appropriate to the respective battery. The battery is then recharged by the alternator. One of the issues could be that they are starting batteries vs deep cycle batteries.

One key difference is the battery plate: Next time you need to replace your rv batteries, consider upgrading to an agm. The 24v sets are charged off their own 24v 30 amp charger.

Unsealed combination (starter/deep cycle) batteries. In a standard battery, it’s recommended to keep it topped off when not in use to maintain battery life. Regarding batteries used for a boat’s bow or stern thrusters:

First, the thruster will suck the voltage down on any but the largest battery bank. As you note, the power drain of a bow thruster is huge. The preferred placement of the optima yellowtop battery/batteries is directly beside the jet thruster’s pump unit.

In any event, meridian is not going to supply wiring diagram. A starter battery can take a short, heavy load, called cca (cold cranking amps) but a domestic battery is designed to take a long, deep discharge at a lower amperage, but over several. A deep cycle marine battery, or trolling battery, has several design differences.

Hi i am installing a bow thruster and a stern thruster on a 45' power boat. A cycle is the term given to a battery that discharges through use and is then bought back up to full charge again. Getting a bit nervous since starting my stb engine restarts my mfd.

Deep cycle batteries can be entirely drained and recharged many times over, where as cranking batteries can't. You’ll have more power when you need it. There is a set for each.

These batteries deliver a large burst of power for a short time as needed for normal engine starting. Power supplied by 180ah alternator, 1200w solar array. Much higher max draw than other lithium batteries.

Have a 2013 391 with 6 oem group 31 agm batteries. It has fewer, thicker plates allowing the battery to provide continuous power output over long time periods.
