Battery Pin and Hole (Erosion)

Hi All - I have 3,000km on my 2019 RadRover and it's been great but I fear my one winter season of riding in Calgary (salt and poor maintenance) may have done in one of the pins on the tray and matching female port on the battery.

Rad Bikes is suggesting I need a new battery and tray however am wondering if anyone else has had the same issue and found a better / cheaper solution? The bike will power on only for an instant and then power off. No error code or anything. Wasn't having any problems with my battery before.

You can see in the pictures: i) the 'gold' casing in the female port is gone on the battery, and ii) the matching pin on the tray has lost its 'gold' casing and eroded pretty materially.

Any suggestions would be very welcome - thank you all. I've checked the forums and not found a similar issue.

My battery (Reention Dorado) didn't erode, but it did have this blue powder like thing on the battery connector.
It was very similar to battery leak on cars.

It didn't erode though.. and it didn't affect anything.
Though, it was pretty much the end of battery life so all I had to do was switch the battery.

I opened up the battery to see if cells are fine, but turns out that cells were so far away from the connector and I didn't see anything wrong inside the battery pack.

Electro Bike World has 52V 17.5Ah battery that fits Rad Power bikes.

Bolton has 52V 20Ah.

Whichever you choose, they're much better deal than stock 48V 14Ah Rad battery.

There's a few things that you can try.
Contact Cleaner along with some emery cloth or very fine sandpaper. Depending on how far gone it is, it may only be a temporary fix.
Or you should be to replace just the connection or the entire case but that will require someone electrical skills and you need to very careful in the process not to short circuit the battery.
Battery Terminal
Battery Case is an example.. You'd have to be sure it's compatible with the rest of the battery mount on your bike

That terminal looks burned, not corroded. Did you blow a fuse or have a large current surge?

I've had good luck cleaning this type of terminal contact using a small wire brush attachment for my Dremel tool.

After cleaning the male and female contacts, you may have to build up the male pin with a bit of solder to get a good connection. I wouldn't try this unless you are proficient with a soldering iron. If you try this, BE VERY CAREFUL not to overheat any internal components!

Really not a good idea.... for the reasons you state and also solder is too soft for this application

I've used this technique successfully in the past but it is admittedly a temporary fix. I think it would be a good idea to find out what caused the terminal to overheat before doing any repair.

From the original post it seems there are some environmental issues at play. Periodic cleaning and some dielectric grease around the connection might be helpful. Also making sure that the battery is snug and maybe further supported from vibration by a bungee cord couldn't hurt.

Another place where ACF50 is a perfect product. Treating the connections twice a year will prevent salt and water damage. ebikes.ca has replacement contacts for some. greenbikekit.com does too.

I don't believe I had either of those but RadPower support did have me replace the fuse - which didn't seem to help (and where I couldn't see that the original fuse had blown). I suspect my poor maintenance through a long and salty winter killed it... and now I will need to pay for my laziness... we will see if these cleaning and lubing techniques work.

The cleaning will only work if the connection material is not too far deteriorated. I'd start looking into getting the replacement connectors as well as that will be the ultimate solution.

FWIW, I have tried to get Rad to sell me a replacement battery tray (with socket, cable and connector) and they wont. I got some kind of gobbledygook answer about it being a "discretionary part" which apparently means thy could provide it, but wont. They suggested I check on social media for a used one.

So here I am, as close to social media as I care to get, and all I can say is what a chicken poop company. Any bike runs the risk being down for an extended period of time because of various real world parts availability issues (particularly at times like these), but if you buy a Rad, they can turn your purchase into pile parts with a very bleak future on a whim, and your only course of action is to buy stuff from other people to get their junk working again. I don't remember any of the interviews Radenbaugh has given during his ongoing media blitz mentioning this brilliant business strategy, but I will certainly remember it when I buy my next Ebike (as if he really cares).

Thanks but my experience with Ali on things like this is dismal, with more than 50% of orders being defective, grossly misrepresented, very late or never showing up at all. I try not to buy from them any more unless all else fails.

Rad makes a big deal about things like "Our bikes are balanced systems where each component is tuned by our engineers in Seattle to work in perfect concert with other parts of the system. For example, motors, speed controllers, and batteries all have dynamic tension with one another, which means one can’t be swapped out without negatively impacting the whole system. Each of these components is manufactured to our detailed specifications."

But when some of their magic parts go bad, they won't sell you replacements, and they have the unmitigated gall to tell you to buy used junk or put you in a position where you have to buy the very parts they put down as a reason for buying a bike from them to begin with.

They also say "When designing our bikes, we keep ease of maintenance and serviceability as a major priority."

Pure marketing BS or hollow (but cleverly evasive) words, if they won't sell you the parts to fix them.

I'm sure the engineers who designed their bikes didn't mean them to be throwaways, but the policies being implemented by the Rad "support" (or lack thereof) organization sure seems to be forcing them into that category if the wrong (or right?) part fails.

Are you the registered owner of the bike, they won't ship you parts if you aren't?

Stolen batteries with damaged cradles or bikes missing batteries + cradles are common

If someone can determine exactly which case this battery has I may have a couple of bare cases I will never use. Shark/Hailong.

Is it a Shanshan case? Which one? Although all of mine are the blade style connectors. These pin connectors were supposed to be an improvement.

This connector has the right format but no dimensions are given:

Select "5 pins male + female" from the drop down box.

Absolutely, and they know it.

To clarify, my battery tray is not corroded (yet), and I have used dielectric grease and protective caps when the battery is off the bike from the beginning. I wanted the tray to be able to carry a spare Rad brand battery (IF they ever become available as spares again), I posted my experience/frustration in trying to obtain at least some the same parts the OP needs as an FYI.

I also asked Rad if I could buy just the plug/connector part of the battery tray and got the following gem of a response, " No...I am actually unable to advise on any DIY stuff on this forum that would void our warranty. That's about all I can say."

Rad loves to threaten to void your warranty. They shipped me a bike with a bunch of metal chips in the front wheel bearings and the wheel started making noise and seized up. I took it apart, cleaned and regreased it and got it working, but it was a bit rough (residual damage to the bearing races), so I asked for a new hub. No way, seems I voided my warranty by identifying and at least temporarily addressing their screwup. Lets just say that squeaky wheel eventually got greased figuratively as well (a new wheel), but the incident and unpleasant interaction with Rad Support foreshadowed future problems like this.

Looks like I and OP will be looking for alternative batteries & mounting plates (or bikes?) soon. The Luna Wolf packs look nice.
