on board chargers

MinnKota 330D three bank Digital...been using it for 8 years now...stays plugged up 24/7 when i am not fishing. No problems

Another vote for a Minn Kota digital. I have a 3 bank that works flawlessly and a friend has used one for several years without nary a problem or issue. One thing to keep in mind, charging is only one part of keeping batteries at optimal levels. To insure years of trouble free battery life get a charger that conditions the batteries as well as charges. Batteries are not cheap, your charger is a critical part of getting the best from them.

my question about on board chargers is what amp to use i have 2 batteries on 12 volt tm and then 1 on cranking duty what do ya use

Exactly my set up. 2 banks is all you need. Motor keeps cranking battery charged

I have the MK 330D on my toon and the NOCO Gen 4 for my bass boat. Both chargers are 10 amp per bank. I don't trust a 5 amp to completely charge deep cycle of AGM batteries. And unless you do a lot of WOT running your motor won't maintain your starting battery.

Not unless your trolling with the big motor it really don't keep it charged. If you have 3 batteries need a 3 bank charger, if you have 2 batteries 2 bank etc. I run my electronics, aerators, bilge pump all off my cranking battery like most everyone, my run time on the lake with the big motor is next to nil, compared with the draw from the other electrical components noted previously.

I don't think I ever had a starting battery issue. But I'm not running anything extra off it.

All my accessories are on one battery and main battery is on the motor
