Hoping for a bit of insight into any issues people have had (or non issues) in placing a decent sized agm (about 100Ahr/30kg's) up near the bow. Whilst i;ve got no desire for a leccie motor i guess its the blokes running leccies up front with fwd mounted batteries to service them who would have some experience.
I'm repowering soon with a slightly heavier motor and adding a livewell down back and wanted to shift a bit of weight forward but not enough to change hull performance...whilst unfortunately its not easy to move fuel forward on mine what i do have is the perfect space already for a big battery and cant see it effecting hull performance much at all..might even improve it into a choppy sea coz anytime i;ve had weight up at the bow she's felt even better.
Cant see the point in adding the weight of a 4stk and livewell on the transom without adding horsepower (even more weight i dont want)...effectively i go backwards in power and are also worried about holeshot and performance going from 2 to 4stk around the 60-70hp mark...a 2stk seems to get it up and out of the water pretty well. So the upshot is i'd like to move some weight away from the transom even if its only 30kg or so on a light 15-16footer.
At this point i'm going to leave the lighter cranking battery down back but would like the big heavy house battery centred low and up forward which i can do ...will mount it securely and perhaps over some vibration rubber or high density foam for cushioning...but are there any hassles you have found with batteries up fwd ?...i figure next size up in battery cables should conquer any voltage drop issue over about a 4m cable run but does the increased pounding it will get cause issues ? Was going to connect the sounder to the transom battery as basic spike protection as they are sensitive things but pretty much hook everything else up to the fwd battery.
Any problems with fwd battery mounting ?...any issues you have found or i should look out for ?...these agm's are supposed to be much more vibration proof so i thought i'd test it out for myself. Will be connecting stereo/navlght/anch light/vhf/bilge pump/deckwash pump/led cabin/led deck lights plus a big HID spottie...all thru fuse/switchboard off the forward house battery. I have a slot i can even put the cranking battery with only a 2.5m cable run and might even investigate that also... but figure i'd try a house battery first to test the added pounding.
Any thoughts appreciated and thanx in advance guys. Perhaps concerned about nothing becuse its quite common to mount them fwd but hoping to hear any issues to watch out for.
Cheers
