Default Batteries Rhodan Zuke 300??

So, ive purchased a Rhodan 36v and a powermania m320v2 charger. What Iíd like to know is the Zuke 300 able to charge house/cranking batteries and also 3-group 27s ?? House and crank are connected via blue seas ACR...can I utilize the aux. power wire from motor to Rhodan batteries? Didnít know if it would be too much draw on a single motor/charging system. My electronics are all usually on while Iím in the boat...twin garmins, vhf, radio w/amp(no subwoofer) sometimes Livewell pump that cycles on/off and I will be adding radar(18xhd) which will also be on whether I need it or not to learn how to identify and use it properly. Thanks

Iím not sure how that charger works. I plan on using a Minn Kota Alternator charger. It is basically a switch that directs the charge to the trolling batteries once the engine batteries are fully charged.

The Suzuki is capable of charging a 12 volt battery, not a 36 volt battery. The 3 12 volt batteries for the trolling motor would have to be in parallel for that to work, and that is really not going to happen as they need to be in series to get 36 volts. You would need a 12 volt to 36 volt charger/converter to make that happen, and you are asking for a little two much expecting the 300 to charge 5 batteries.

This can be done, but it is a bit complicated. Mercedes diesels have been doing it for years. 24 volt crank-12 volt run.
If you're still interested, let me know and I'll work up a schematic as well as parts list.

yep, I agree, but just wanted to confirm, kinda felt a single motor and 5 batteries isnít going to work well. Charger I have will be wired to when I get home Iíll just plug it in and charge em up. Probably will never be using them 2 days in a row the way my schedule is.

Since u already have an acr btwn start and house batt, u can skip the aux alternator output unless a suzuki expert has a reason why not.

You can use a yandina combiner, stealth, or minkota charger to take the excess power from the house batt while running and charge the TM batts. Minkota has a low current output, stealth chargers always seem to be reported as backordered. I have the yandina and am happy w/ it.

I’d love to get a minn-Kota but I don’t have shore power. I have a single 200hp Suzuki that would need to keep everything charged. I’d like to hear the setup you end up with and if it works.

Yardina Trollbridge. Look it up. Got one for my 36 volt minnkota. Easy to install and works like a charm.

No way this can be answered unless you know a number of factors.
The Engine will have a MAX alternator current output.
Without a trolling set of batteries, that Alternator powers all your electronics while operating plus charged up any batteries that needs charging (house, starter). Add in some loss due to efficiency (maybe 10-20% is a good start).
Generally, the alternator charging up the batteries will charge slower when the alternator output is lower (idle speed, or under a heavy charge load).
You will have to figure out how much of each battery needs to be charged (amp-hours) and how many batteries.

You will have to figure out how much max current per channel the onboard charger can put out when running from the alternator.
I was not EASILY able to find that info on the trollbridge. Some of the info seems misleading (up to 85A 36V , then later says Uses only 1/2 amp when charging).

But lets say its 10A per channel and 3 channels (that's a decent charge current for a 3 bank charger).
Lets say you already have a full house battery, so the troll bridge starts charging right away.

If you used up 40Amp-Hours from your battery (40% depleted 100Ahr Battery) then its going to take at least 4 hours of running your engine to charge that depleted trolling battery.

That just did not seem to make much sense to me when I looked into it. Since I have power at my dock, I just have a 3 bank 5A charger (5A per bank). SO I know in 10 hours I'll get most of a 50Ahr charge back (it goes into low current charge at the end).

anyone who has a troll bridge, if I have my math wrong, let me know cause I don't have one....

i already had a charger for my start batteries so adding the troll bridge just added the option of adding some charge back to the batteries as i run...we have 2-3 hr runs to our fishing spots,but at the dock the start battery charger tops off the trolling batteries for me( if i remember to hook it up..lol)

the most i have used my trolling batterys in one day was about 50%,that was over 7 hrs of use..

How much current can each bank on the troll bridge supply? I have a hard time reading what they specify for that on the website.
The trollbridge is hooked up to one bank of the main battery charger?
Have you been able to figure out how much current each bank on the trollbridge is getting while running as well as on the main charger?

no i have not checked the charge but the batteries were completely dead on sat be cause i failed to charge them from the last 2 trips,i used them hard and only ran the motor about 1.5 hrs,so i hooked them up to charger (4amp)thru the port start battery sat night at about 830,unhooked at 430 am drove 3 hrs to our spot and checked,they were 89-90% charged according to the beeps on the rhodan.they were so dead sat they would not go to 36 volt..

only my port motor is hooked up to the trolling batteries

no clue how much charge they are getting,i have 2 start batteries,2 house batteries and the 3 trolling motor batteries...yamaha f150s with the accessory charge hooked to the house batteries.
