Onboard charger question

[HUNTINGMAN]

I am in the market for a new onboard charger. I am wanting a 3 bank, 2 trolling and one cranking battery. What does the amps need to be for these, i am thinking 5 amps per bank but know nothing about this stuff. I dont want to spend an arm and a leg on one either, around 150 or so, i may just end up getting a 2 bank, what is you guys thoughts, any input.

I got the one from cabelas so far so good. It has the ability to give all the power to 1 battery. If the starting battery doesn't need charged it will give all 10 amps to the trolling battery etc. Every 21 days it drains the batterys some then recharges them to help maintain a good battery.

Get a three bank. I had a two bank for a long time and always wished I had the three. got the three and haven't had any cranking battery issues since.

I recently upgraded my trolling motor to a 36volt XI5 , can't say enough good things about this motor especially if you fish alone like I do 95% of the time. I put in a MinnKota MK 330D On-Board Battery Charger (3 Banks, 10 Amps per Bank) I paid a little over 200.Works great. I moved my 2 bank over to my starting battery.
Get everything on a charging system takes allot of the headaches away from a dead battery.
