A while back I did a video on charging a 24V bank of batteries (i.e., 2 x 12V batteries connected in series to make 24V) from your outboards 12V alternator using a Yandina Trollbridge. That video can be viewed here:
• Charging a 24V battery...
That system is perfect when you have 2 x 12V batteries (either AGM or Lithium) but it won’t work if you have a single 24V battery because it relies on being able to automatically switch the batteries between a serial and parallel connection depending in if the trolling motor is in use (series) or the batteries are being changed (parallel).
With a single 24V Lithium battery I needed a different solution, and this is what I came up with. It has done half a dozen charge cycles at the time of writing as is working flawlessly.
As well as allowing me to charge my trolling battery while moving between fishing spots I can also use my 12V charger at home to charge the 24V battery, saving me from having to buy a dedicated 24V lithium battery charger.

eBay: ebay.us/AVdYpk
There are both 10A and 15A models listed,
choose the correct one for your outboard.
Remember, these are output amperages,
the input amperage will be double.

Timely for me. Specking up the new boat, and this is a hot topic! Thanks.
Glad it was helpful!
@@weFishAU I just saw the waiting list for the RBC - Bugger!
(I have been a member twice, and was hoping to make it three!)
Yes, I did a video on it a while back. I'm not sure if the video had any contribution to that but I did notice the waiting list is longer after than it was before. Pity they can't expand with more parking space.
@@weFishAU I'll just have to suck it up and park with the hoi polloi!
Had to do that often enough when I was VMR.
Unfortunately. All the ramps around Brisbane need more weekend parking spaces.
I've watched your other charging videos a lot. I am in process of updating to the trollbridge 12x24 with the built in combiner. I was switching over to 12v lithium x2 for the trolling motor. Watching this new video, I'm wondering if you seen any major advantage of going with this new system?
No major advantage IF you have 2 x 12V batteries for your 24V bank. I went with the new system because I got a very good deal on a single 24V lithium battery. Had I had a bank of 2 x 12V I would have stuck with the trollbridge.
Thanks for responding. I am installing everything on a tritoon. I removed the changing room area and am making a cabinet with a few extra items to make the longer fishing days more enjoyable, and the over night trips more like a camper. I am adding a 6000w inverter, dual 100ah lithium batteries, 400 watt solar blankets for over the Bimini top, a small fridge/freezer combo, and a few drawers for my tackle and gear. Luckily my nephew works in a cabinet shop and can auto cad all my dimensions and plan the cabinet out in a 3d model for me. Will be making it out of polyurethane sheeting.
Sounds great. I particularly like the idea of the solar panel. I hope it doesn't take you too long to complete.
What if you don’t have seperate charging aux cable from outboard?
In the diagram at 8:00 into the video, connect the Auxiliary charge line to the positive of the house battery instead of the aux from the outboard.
The green plug on the Victron unit can be connected to the ignition switch so the unit is only active while the engine is running but I have found its internal charge detection works fine.
would it be safe to run the outboard and trolling motor simultaneously?
If you mean running the outboard in neutral to charge the batteries while using the trolling motor, then yes.
Great video, I ran across this when searching, I am updating my trolling motor to a 24v unit along with the batteries you even have basically the same outboard. The only difference is that I also will have solar panels connected. So my question to you is do I have to disconnect my solar when the outboard is running or will it be fine to leave connected. thanks and have a great one.
Thank you.
I have since added a portable solar panel that I run when I am anchored up for a while, but I am sorry, I don't have an authoritative answer to your question. I talked to some RV people about the wisdom of leaving the solar connected while the motor is running and their opinions were divided. I erred on the side of caution and put a switch between the solar controller and the battery so that I could turn it off if I move a bit. Since my setup is portable it isn't a bit deal to manually switch it in or out of circuit.
Thanks I finally have gotten all the bits and bobs in the mail and have installed as per the wiring in the video, I did get the isolated version. I would like to ask if it is not to much trouble could you post your settings on the Victron as I don't want to fry anything.
I need to be at the boat so I can read the settings. I will try to get down there this afternoon.
Can you DM me on Facebook @ weFish AU
I have the screen shots but they can't be posted on CZcams. Alternatively, give me an email address and I can send them there.
How are you finding your cranking of the engine as lithium battery don’t have as much crank power. As normal battery’s I. Ran a lithium in my motorcycle and it would hardly swing the moter enough to fire , took bike to shop showed them. They replaced it 2 times in 3 months. Sending them back to manufacture. Replaced again with a normal lead acid. Wound engine over so fast you can hear starter spinning while engine runs.
I have heard similar stories about Lithium cranking batteries. For that reason I have an AGM battery for cranking, a 12V Lithium house battery and the 24V Lithium battery for my trolling motor. The Lithium batteries are perfect for their assigned use.
If you want a lithium battery for cranking, look into Anti Gravity batteries
Thanks for the info. My cranking battery is still reasonably new but I will definitely look into it when it needs replacing. Great weight savers.
@@weFishAU Absolutely! My brother has their ATX-20 sized battery I believe and it’s less than half the weight of his stock Miata battery… amazing stuff
I see the highest amp is 15 in the orion 12 to 24. My suzuki 250 has 54 amp alternator that outputs 38 amps at 1000 rpms. Safe to use 12/24 - 15 amp inverter?
The 15Amp is on the 24V output so that is 30Amp on the 12V input. Depending on the safety circuits, 38Amp might be okay. Safest thing would be to drop Victron an email and ask before you buy.
Thanks. Victron just said to use the 15 amp. I use my trolling motor (built in gps) on ocean to hold in one spot ... trolling to counter wind and current. I will keep my outboard out of gear and idling while the trolling motor runs at the same time. If its blowing 15 mph, the trolling motor is running at high speed almost continuously. There are no issues with battery receiving 24 volts from victron and at the same time it's being drawn out to keep the troller running, correct?
No problem at all to have it charging while the trolling motor is running. If you have the trolling motor running at full speed for an extended period of time I would recommend going with wire that is at lease one gauge heaver than they recommend and buy a very good quality circuit breaker (to avoid heating the circuit). I would probably also spring for one of the exceedingly expensive Minn Kota plugs (if you need a plug) in that situation.
Thanks for your fast replies.
You're welcome.
Hello sir are you still alive ?
can i use 2 12 volt 100 amp alternators with 2 24 volt transformers connected to a 24 volt battery charger to charge 2x12v 300amp 2x12v 300 amp batteries connected parallel, however while being charged by the alternator the batteries will load 2 2000 watt motors, wich in turn will also move the alternator. it is a 4 back wheel 2 front wheel electric bike project. i will design the mechanics, however i would either have 4 more batteries in storage so i can switch from using to charging ?
I'm not sure I follow exactly what your setup is. 2 x 12v batteries in parallel only need a 12v charging source. Did you mean series?
I can't make sense of the maths involved either. The power required to turn the alternators is a large part of the output of your motors, adding the inevitable losses in the system I just can't make the numbers work. Maybe I just don't understand the setup but I suspect you are trying to charge the batteries using part of the output power of the motors without factoring in the losses involved.
In my opinion I don't think adding an alternator that is driven by the electric motors is going to be of any benefit. If anything, it will reduce the range of the device rather than increase it. If you devised a system like the KURS system in Formula 1 cars then there may be some benefit but it is also unlikely that a bike would recover sufficient energy under braking to be worth the cost.
I hope this helps and sorry if I have misunderstood your use case.
Isn’t this a copy of the system invented in Tennessee. The difference is, that system has a dc/ac charger along with it
No idea, but with 7 billion people in the world it is no surprise that others have similar systems.
Loool 360 watt.
Crazy prices on this and that People at all buy victron
The prices didn't seem out of line with comparable units when I researched the purchase. Do you have the brand and model of a unit of similar quality and lower price that you could share?
Hope u dident payed no more then 15 dollar for it
I was lucky enough to get one at the lower end of their price range, which is in line with comparable units. I am extremely happy with it so far.
