So ive done a ton of research and didnt quite find what i was looking for so i am hoping to get some real life experiance from you guys. I know minn kota can help but i wanna hear whats worked or not.
I have a 19 ft. monark with a 80 lb 24v ipilot. i moved 2 lead group 27 batterys to the back of the boat to help with shock but im still only getting 2-3 hours out of them. I did not use marine grade wire when i did that. so thats one problem i need to correct. its the right gauge but stiff as a board and like 5-10 strains of copper wire. ill switch that to marine grade. i HAVE to move the trolling motor batterys back to the front, theres way too much weight in the back as i found out on lake michigan this past sunday. I also use the batterys nonstop for trolling, sometimes with the help of the kicker, sometimes not. but here are my questions
1. do you guys get better life with gel/agm batterys as far as shock goes?
2. im going from group 27's to group 31's. any brand preferance?
3. i wanna add this minn kota dc alternator to charge them on the fly however im wondering 2 things. first, can i install this on my 4 stroke kicker and charge my batts while im using my trolling motor? or is that too much for the batts? secondly, im getting conflicting reports. im reading that its best to slowly re-charge your batts to increase the life of them, i do have a on-board charger for them but how good is it for the batts to get charged quickly with the main motor or kicker? i read one guys post saying he can buzz around the lake once or twice and have them charged again...recharging in 10-15 minutes on the lake cant be as good for them as letting them trickle charge all right right?
4. my trolling motor is hard wired to the batts with a 60 amp breaking but im reading i should have a master on/off switch on it so i dont fry the circit board on the trolling motor, ill add one but do i need one on my ground wire too?
thank you much in advance!!
