Rad city step through battery used for powering an electric canoe motor

[Art Deco]

Way /off topic/ to the OPs question which is a good one, but it seems like a combo trip of floating downriver with an ebike (in an inflatable boat) and biking back pulling the deflated boat on a trailer would be an epic adventure. What could possibly go wrong?

Ok, the easiest way to do this is to order these Hailong connectors:

Hailong Battery Case Discharge Power Connector 4pins or 5pins Male or Female | eBay

Use for: Hailong 1 battery case, Hailong 1-2 battery case, Big hailong battery case and samll Hailong battery case.

www.ebay.com

They ship from China and may take a few weeks to arrive. You will have to solder your own wire to the larger pins on each end. The 3 small pins in the center aren't necessary for what you want to do..

Here is a you tube video of someone who made a second battery adapter for his Rad using these connectors:

Thankyou very much for this information. i think I am going to be able to do it. this is wonderful. Don't go away, though, in three weeks when the part comes I may need to speak to you again

From what I've seen, these things don't have much power, like they're made more for a lake or pond. You might want to look into whether such a thing will work against the current you have to deal with. I'm sure it varies by location, but where I've seen the St. Lawrence something with a few more horsepower would probably work better.

You know how much a replacement battery costs, don't you?

I have a sea kayak. but, it is the same problem. Also, too many rocks to use a rowboat. no, I just want to find a solution to the battery question and not embarcation questions
thanks G

Hello again
Still looking into this and trying to understand.
Relating to that, i have a couple of more questions:

the first has to do with the Heileng plug adapters from China. I can get a replacement cradle for the battery, which has a connector and a wire coming out of it for fairly cheap. Would this also work?

secondly, regarding the waterproof case for storing the battery. It seems a bit counter intuitive to pay a lot for a waterproof case and then drill a hole in it to pass a wire. I am not at all familiar with these things, though, and may be off base
Thanks G

On the bold, some may consider a very similar issue, where you are taking and introducing a very expensive battery and running it in an environment where it's very likely going to get wet, destroying it?

If you would like to try your idea, get a cheap battery to see if you can make that work (or not)?

The replacement battery cradle would also work and might be more readily available than the Hailong connector.

The point made by @AHicks about possibly ruining an expensive battery is well taken. A watertight enclosure would be a necessity. A hole in such an enclosure for the wire could be sealed with silicone.

Why not just use a 12V deep cycle marine battery instead? That way, you wouldn't need the 12 / 48V converter, the connector or the waterproof case. When you add up the cost of all these components, the deep cycle battery might actually be cheaper. Yes, it's much heavier but stores roughly the same amount of energy. It is also far cheaper than a replacement e-bike battery should something go wrong.

I had thought of these points. But, thanks for raising them again. Yes, that is the decision. A deep cycle marine battery weighs about 50 pounds, or more. Pretty heavy to lug around in a canoe or kayak. There are lighter lithium ones around but the cost is pretty close to the cost of my evoke battery. It is indeed a bit of a quandary. I certainly am and will consider these suggestions.
Thanks for the input G

I share your interest in finding alternative uses for these expensive e-bike batteries. So far, all I've come up with is a portable light source for power outages and working outside at night. It also works well in my utility shed which has no electrical service.

Another project is a 48VDC to 110VAC inverter such as this one:

Amazon.com: TS-1000-148A DC to AC Inverter 48VDC 100VAC/110VAC/115VAC/120VAC 1000W True Sine Wave : Automotive

Amazon.com: TS-1000-148A DC to AC Inverter 48VDC 100VAC/110VAC/115VAC/120VAC 1000W True Sine Wave : Automotive

Conversely, I've also been experimenting with ways to power my e-bike using other battery types. I found these adapters which are available for most brands of power tool batteries:

I made a "range extender" kit for my bike using this adapter with my supply of DeWalt tool batteries:

I have seen this idea used to power trolling motors as well:

Of course, this method is only cost effective if you already have a supply of power tool batteries on hand.
