Strange battery arangement

[mad_boater]

Has anyone come across this before.I have had a survey on a sealine S360 statesman circa 92. The anchor wynch and bow thruster are powered by there own 110v battery which is situated in the bows and there is no means of charging it apart from the trickle charger the owner has installed. I would have expected it not to have a battery at all of its own but to be the connected to the main system via heavy cables.Is this normal on these boats? Th wynch also runs slow as you would expect and the bow thruster is no better.

A bow battery was common, charged from engine or mains.

This may be a owner retro fit, you should fit a VSR to charge it from port engine / mains charger.

A voltage 110 volt is very high normally 12 volt DC.

battery problem

Sorry about the 110v I should have put 110amp.By the way what is a VSR you mention in you post. I instaled an electric anchor wynch on my previous boat and wired it straight to the main domestic bank via a trip switch type of fuse.I would think both wynch and bow thruster would work better when the engines were running due to the higher voltage being put in. Running it to the batterys means it wil be charged by the 240 charger also.Would this be good practice?

mine are both run from engine batteries which is fine because both winch and thruster are only ever used when engines are running and replacing the charge via alternator. Your arrangement is OK, in fact good to have independent batteries but without charging sytem next to useless IMHO. A short trip away from marinas and shorepower to run the trickle charger and surely they will go down.

Sounds like a bodge job to me, but saying that id check the wiring again to satisfy yourself.

Reason being on some larger boats its cheaper to fit a battery or 2 in my boats case under the bed next to the BT motor thatw ay you eliminate the long cable run which in my case it was cheaper to buy 2 batteries than buy the cable run from the engine start batteries, you also gain more amps as the cable run is a lot less.

2nd point, you may find the link from the winch is actually to charge the battery as the winch cable has 12v from the boats say maybe start battery, however there MUST be a diode blocker between the BT battery and the winch cable, I have fitted this arrangement on my recent BT fit and it works a treat, the BT batteries are always kept 100% charged.

I have also fitted my inverter under the bed for the cabin tv so we can watch in bed when not on mains hook up.

Hope this explains this as I once attented a burnt out anchor cable that was wired to a BT simply the cable area was way too small hence it burned out the cable.

Thanks for the reply,sorry I could'nt understand this bit in your reply


'you may find the link from the winch is actually to charge the battery as the winch cable has 12v from the boats say maybe start battery'

You will have to excuse me I'm thick.

There must be a cable to charge the battery from elsewhere in the boat, there will be cable from each helm to control the solenoids for up and down, so there must be a cable to charge the battery somewhere, sealine would not normally fit a separate battery for the winch so id say the battery has been fitted to support the BT only and is charged from the winch cables as per my boat.

Thanks for that volvopaul I will have to investigate further if I go ahead with the purchase.
By the way your name suggests are you familier with volvo engines.The ones in this boat are KMD42's with to the moon and back hours 2,500 for a 92 boat.We took the boat for a sea trial and the starboard engine over heated with water overflowing from the header tank also the clutch on the compressor started giving off sparks.Would you insist on an engine surveys from a volvo dealer before buying the boat or are they a waste of money as some people say ?

 

[volvopaul]

You dont need a volvodealer I can do the engine and gearbox survey for you to find any faults and a sea trial.

pm me if you want my numbers.
