The boats that I have had previously were simple enough that one deep cycle battery ran everything. I bought my first bass boat last summer and didnt really pay too much attention at the time to familiarize myself with the wiring and battery connections too much but now that I have, Ive got some questions.
Theres 3 batteries. 2 deep cycles for the trolling motor an one battery for the motor and other electronics. I verified that the 2 trolling motor batteries are indeed only connected to the trolling motor. The battery that connects to the outboard motor, is also connected to all the electronics in the boat which includes the tilt/trim, all the gages, bilge pumps, livewell fill and aereator pumps, flasher, front and rear sonar. The question is, should the battery that starts the outboard also be the one that runs all the electronics? It seems to me that I am at risk if I am running livewell pumps and sonar units all day that I might run down the battery and get stuck. Shouldnt the deep cycle batteries that run the trolling motor also run most of the electronics and pumps?
Also.
The batteries are only 2 years old. New June 2004. They worked fine last year. Fish all day. I kept them charged after each outing and charged them up fully before winter and didnt recharge them at all during the course of the winter. Now I cant seem to get them to take a charge. They worked fine last year. Could they be that shot already that they wont take a charge? Only 2 years old with not too heavy of useage?
thanks,
