Amperage question

[mikesbuick]

I have a 2000 Nitro 205 Sport with a 150 xr6 Mercury outboard. It has two voltage regulators part # 854515. I have found information that states they are 40 amps each. Do I times this by TWO for charging starter and 2 deep cycle batteries for a charging rate of 80 amps? I have purchased a Yandina system to charge batteries off motor. Also if a higher amperage would work better for charging is there an option for a higher output? I use the deep cycle batteries for a 24 volt trolling motor. Thanks!!!

It is 40amps total ...20 amps per rec/reg

Thank you for the reply. I was kinda expecting your answer but was not sure. I was hoping for more amperage to tell you the truth. I am installing a Yandina system to charge not only my started battery but also my two deep cycles for 24 volt trolling motor. Is this regulator an appropriate one for that? Meaning will these batteries get enough charge when motoring in the water? Or am I able to get new regs with a higher amperage? Any help would be appreciated. I will be going on an extended fishing trip with no easily obtainable electricity is my reasoning here. Thanks again!!!!!

Output is limited by the stator's ability to generate current, and the number of hours you plan on running the main motor at high rpm (4000+ rpm )

So unless you plan on running the engine near wide open, for 7 hours a day, your trolling motor batteries will likely be dead in a couple days.

You would probably be better served by purchasing a small portable generator.

Don’t know it it’s enough until you tell us how much you use.

What is the current draw of your trolling motor?

Trolling motor have Digital maximizer circuitry? Would cut current draw in half

Trolling moter has a 50 amp breaker it is a motorguide tracker 67 ilb thrust. Original one that came with the boat in 2000-2001.

trolling batteries are typically charged at a low current rate for longer periods of time. Your engine charging system is not adequate if you want maximum battery life. Deep cycles are a pain to charge unless you run a plugin charger to them for several hours after use.

Charge the battery from your vehicle. That's the fastest, least convenient, but only practical way when there is no source of shore power. As was pointed out, charging a deeply discharged troller battery from the engine requires wide open throttle operation for hours. Costly and impractical due to the limited charging system output. Lead acid batteries can be charged at a maximum rate of 20% of rated battery capacity.
