o where to put my two new 100ah batteries

[Kleyny]

I have a 4.6m tinny at the moment the i have a low profile 55lt fuel tank up the front. nothing really at the back.

So my question is do i remount the tank at the back and put my batteries up the front?
OR do i leave the tank where it is and put the batteries in the back?

the batteries weigh 3kgs each. they will be running my bow mount leccy motor.


oh i also plan on cutting into my front seat to fit a esky/kill tank. This will have the ability of holding roughly 60lts but hardly ever that much.

your thoughts

I always thought batteries up front was a bad idea as they will experience a much rougher ride up front with more banging and harder hits, which isn't too healthy for the cells.

I'd be inclined to put them up the back, however, only if weight distribution allows it. Nothing worse than a stern heavy tinny. I have my single 120Ah battery about midship in my tinny. Key to good boat performance is good weight distribution.

Neil,

Make sure that they are properly secured and wired. Also length and size of wiring.

Would also recheck the weight of the batteries. Seems a bit low.

Enjoy the fishing.

Sorry the batteries weigh 30kgs each.

anyone else?

It could be alittle bit of trail & error when setting up your boat but I would start with them up the back one on either side for balance with the fuel tank up the front then move then around if it's not suitable.. You will need to do some water testing which isn't such a bad thing!

Yep, If possible down the back but before you go to the trouble of fitting etc take some drums of water and put them where you'd like the batteries and see if the boat performs OK.
If it does not go so good then move them about the see where the sweet position is.

Don't forget they do not need to be in the one place.
Wire is good. It can be run and join things anywhere.

Gees by the time you bung in 2 batteries, full tank of fuel and a full kill tank it's going to add a lot of weight. 2 BIG blokes worth I reckon.
But with the fuel and kill up the front..say...120kg and you and 2 batteries down the back...60kg+ you then it may not be so bad balance wise.

Cheers then

PS make sure the batteries are accessible because it's a pain in the date if you cannot get to them for any reason.

what can handle vibration and impact more :)

back end of the boat is generally the least banged around, i have my battry up the front and have moved it aft as it was getting pounded around.

batteries dont like being abused

Neil,

I agree with Finga,

I'd recommend putting them in the centre of your rear seat, or rear deck. I recently set up my Bluefin Troper 4.75m and initially put two 130amp/hr batteries up front along with the a livewell (fuel tank centre mounted) The ride became very wet and slow.

When I moved the batteries back, it got more of the boat out of the water on the plane and went 4km/h faster and much drier ride.

It might take some trial and error to get it right.

The back of the boat will give them a smoother ride as well. I'd also recommend putting your livewell back as well.

Cheers,

Matt

If i fill the kill tank i wont care how slow she goes or how wet i get.;) I dont think the weight is a huge issue as she will still hit full revs with roughly 400kgs of camping gear in her.8-) It may stop me from reproping her but.

I know what you guys are saying in regards to the softer ride. So i might put them in the back under the left hatch. Because when i head out by myself now she does seem to lean to the right a bit.

thanks
