Connectors question for electric outboard

 

I'm planning to use an electric outboard on the West Marine RIB 310 for my trawler.? The dinghy is about 10' long, weighs a little over 100 pounds empty, plus 2-3 "solid sized" adults, plus motor and battery.? Current plan is to experiment with a 48V Hangkai electric outboard, powered by a BTR 48V Ebike battery.

Question:? What connectors are best for using in the marine environment?

I have experience with Torqeedos, and they use Anderson Plugs.? Is that the best option for being able to quickly plug between the battery and the motor?

One thing I want to do is put a small box between the battery and motor.? The box will include a battery switch on the positive leg and a Victron battery monitor on the negative leg.? While the Torqeedo used Anderson type connectors, I believe 120A type - I'll probably go with 50A Anderson connectors for the Hangkai.? This is because both the batteries and the motor use small guage leads - 12GA at most.? This is challenging enough to crimp into the pins of the 50A connector (intended for 8ga wire).? ?I have a crimper that I use for most of the large pins and terminal lugs, but have to resort to using a bench vice to crimp the connectors on the small motor and battery leads.? I'm planning to use 8 ga wire for the longer runs.? ?The motor is rated at 1000W.? ?I'm assuming I shouldn't be running much over 20A peak, probably more like 800W for typical cruising.

The Hangkai is tiny compared to the Torqeedo 2T.? ?But I'm really curious to see how the Hangkai does, and am REALLY hopeful that it works out.? At $350, it's less than 1/10th the cost of a Torqeedo.? ?The Ebike 48V batteries seem to be much better priced and much more available than 24V lithium batteries.? My hope is that a 50A Ebike battery will get me at least 2 hours of run time at around 800W on the Hangkai - and I'm REALLY hopeful that 800W will be enough to push the dinghy at least to 3-4mph.? ?

I'm looking forward to being able to put some data together to compare the Torqeedo to the Hangkai.? I understand that the Hangkai has less than half the power of the Torqeedo (and the prop on the Hangkai also seems tiny compared to the Torqeedo prop) - but if it can honestly put out what it claims to do, I think that'll be sufficient for a small dinghy.? Given my battery bank, 800W would be a good burn rate.? I know it'll never get me on plane or win any races.? But if it gets me from the boat to the beach, and lets me toodle around a little from time to time, that'll be just fine.

John,? As far as I’ve spirmented,? you are thinking streight and are barking up a sound tree.? With a 36V Motorguide and a ebike battery, I push my HA-18 at about 4 mph.? Your prop is as important as the particulars on the motor.

Hi John,

I use 50 amp andersons on my dinghy motor. They do take a beating. I have to clean them every few months. Keep in mind, I get them wet frequently and they have taken more than a few dips in salt water. Salt water corrodes them pretty quick. Ill eventually try another solution.?

I can't speak for the Hankai specifically, but 800 watt input power should be enough for 4mph with a little margin. Power needed to go faster then 4mph will go up exponentially.?

John,
?? I have the Hang Kai 1.2 kw as well. It's going on a 12 foot cat dinghy I'm building. The motor is direct drive, no gear down at all. That's why the prop is so small. I consulted with my Aussie buddy who makes the pedal drives for the R2AK race. He says he thinks it will be good for 10 knots with my boat.

??? I looked at ebike batteries too but am leaning now to the smaller lifepo4 or NMC rack style batteries. 1.2 kw and 35 lbs. https://bigbattery.com/products/48v-honey-badger-nmc-28ah-1-2kwh/?utm_source=Website&utm_medium=Title&utm_campaign=Analyst&utm_id=ButtonsCamp

?? One great thing in the Chinglish instructions for the motor is "protect from rain". It's got the big open motor vents so I think I'll 3d print a dorade style cover for those.

??? Plan is to test boat with one motor. If motor seems OK functionally but perhaps not enough power then get another one and gang them together. If the motor is crap then get an epropulsion instead.

?? I'm excited to see someone closer than I am to actually testing. Please let us know how it works out.

There are sleeve bushings for those Anderson connectors, to better allow the use of smaller wire:



I have the Hangkai 2.2kW motor, and used it briefly on my five-meter cat, before switching to the ePropulsion Navy 6.0 Evo:



Speeds were in the neighborhood of 7.5mph.
 

You can also get SB50 / PP75 contacts that support 6AWG, 8AWG, or 10AWG without a bushing:

I use a 20Ah, 48V eBike battery and custom built electric outboard to push my 23' sailboat around (a 2500lb?keelboat) and use Anderson connectors. You can also get rubber 'boots' for the connectors?to help protect them (I use these and can recommend them).
?



I have also tried a Hangkai with my boat and it worked well, though the throttle was awful (very sensitive). I cobbled?a fix, but beware.

Revisiting this question:

I'm using an electric motor and battery for my dinghy.
I've used Anderson connectors (100A and 50A) - and they're fine electrically.
But the 50A blue Anderson connectors corrode horribly in the salt environment.

I've seen XT60 and XT90 connectors, and think I've heard of people using those for solar connections (as well as being used in RC stuff).

Would XT60 connectors do better in a salt environment than Anderson connectors?

Hello,

XT60 connector have gold flash conatct plating (good for salt environment ?) but no IPxx specification...

Take a look at the IP68 SBSX75A serie connector :?

Sincerely

Thierry
 

John,
?? I'm building a 12 foot cat dinghy out of foam and glass. About 120 lbs. I also have the Hang Kai 1.2.? Hopefully will have the boat running by end of summer.
?? I'm probably going to go with a small server rack lifepo4 that weighs about 40 lbs so I can carry it home to charge. The prices are getting better so waiting until end to buy it.
??? The 10 foot version of my dinghy would plane at 14 knots with one guy on a 3 hp gas honda. So I asked my Aussie propeller expert to look at the Hang Kai. He thinks we'll get at least 10 knots. So I'll give it a shot. If it looks promising I might get another and gang them together. Would also be good for redundancy.
??? We discussed the prop. The motor is geared one to one, so the prop is spinning at 3000 rpm or so. That's why it's small. Depending on how things go I've got an idea of an adapter to gear it down and fit a bigger prop.
??? Keep posting. I'll let you know how it goes when we get the thing in the water.

Is there a difference in contact metal between the blue vs gray Andersen connectors?

I have used 50a Andersen with gray shells on my boat and also on my 1920 antique electric car for a very long time.

EV conversion folks have used all sizes of these Andersen 2-cable connectors as power connectors in EVs for decades.

The contacts are heavy nickel plated, so they would be as suitable for the marine environment as any nickel plated marine connector, e.g. ring lugs.? I don’t know of any direct salt environment use of these, but it does surprise me to hear of horrible corrosion.? They certainly are not at all sealed, so you’d expect corrosion on par with any other high current nickel plated lugs.

Dimensionally, I think these connectors preclude applying any heat shrink on the cable-lug connection else the lug won’t slide in and lock into place…seems I tried that once and it didn’t work.

I don't know...
I've used Anderson connectors on boat projects on Lake Travis - 200 miles inland, and freshwater environment - and had no problems.

Maybe my learning here is that I can't leave bare connectors outside in a salt environment.? These were the connectors on the battery - so there was power applied to the lugs on the connectors - just nothing but the salt air to make the connection.

It might be an interesting experiment to see if the gold(?) plated contacts on the XT## connectors would fare better.? The thing I don't like about the XT# connectors is that the lugs are only solder type (as far as I can tell) - and I've been told that in the high vibration marine environment, one should NOT solder connections.? ?I can buy connectors that have 6" leads that I then use heat shrink marine grade butt connectors to attach to other wires - but that seems iffy - and maybe only adds yet another connector if the manufactured sets are soldered anyway...

I have used 50a Andersen with gray shells on my boat and also on my 1920 antique electric car for a very long time.

EV conversion folks have used all sizes of these Andersen 2-cable connectors as power connectors in EVs for decades.

The contacts are heavy nickel plated, so they would be as suitable for the marine environment as any nickel plated marine connector, e.g. ring lugs.? I don’t know of any direct salt environment use of these, but it does surprise me to hear of horrible corrosion.? They certainly are not at all sealed, so you’d expect corrosion on par with any other high current nickel plated lugs.

Dimensionally, I think these connectors preclude applying any heat shrink on the cable-lug connection else the lug won’t slide in and lock into place…seems I tried that once and it didn’t work.

Revisiting this question:

?

I'm using an electric motor and battery for my dinghy.

I've used Anderson connectors (100A and 50A) - and they're fine electrically.

But the 50A blue Anderson connectors corrode horribly in the salt environment.

?

I've seen XT60 and XT90 connectors, and think I've heard of people using those for solar connections (as well as being used in RC stuff).

?

Would XT60 connectors do better in a salt environment than Anderson connectors?

Hi John,

?

I use 50 amp andersons on my dinghy motor. They do take a beating. I have to clean them every few months. Keep in mind, I get them wet frequently and they have taken more than a few dips in salt water. Salt water corrodes them pretty quick. Ill eventually try another solution.?

?

I can't speak for the Hankai specifically, but 800 watt input power should be enough for 4mph with a little margin. Power needed to go faster then 4mph will go up exponentially.?

I would go through Anderson connectors every few months on my dinghy, what final worked extended use was Trolling motor connectors, they are made for this exact environment. ?Provided you can find then in the gauge you need:

"Is there a difference in contact metal between the blue vs gray Andersen connectors?"

None.? The contacts and housings are available separately:



The contacts are usually Silver plated, but it looks like Tin plating is an option:



Tin plating may fare better in a marine environment:


 

I'm pretty sur all the Andetson 6ga contacts I have been using are nickel plated.? Silver is very nice---until it tarnishes...the ampgour gage on my 1920 Milburn electric got very hot one day---the culprit?? Silver plated washers that had tarnished.? They are still silver now, but cleaned and kept tight.

Jerry,
Any chance you have a line drawing, plans, sketches, or outline of the dinghy you are making?

Ric,
?? Mine is bigger than the prototype at 4 meters. I also beefed up the gunwhales a bit to handle the scrum at the dinghy dock. Designer is an Aussie, Craig Clos. He has several videos on YouTube https://m.youtube.com/watch?v=SA6cDk2Imb0&t=3s&pp=ygUTbWFnaWMgY2FycGV0IGRpbmdoeQ%3D%3D
He made the plans for me and was very helpful. I lost contact with him shortly after he launched the 8 meter powercat (full interior, trialed at 22 kts on 2x30 hp Honda with 4 peeps). He had some health problems so I fear the worst. I'll keep trying to track him down. Last address he used was apc.tender@...
?? For my boat next step is final structural taping and float in water to figure out weight and balance so I know where to put seats.? I've given up on electric motors for now. I'll wait for better stuff. Gonna start with gas Yamaha 8.
Jerry
