DOST IS NOW IN RECEIVERSHIP

Since you live in Canada just go to biktrix.ca, click on Accessories, and then scroll down to Rhino batteries.
 
Oh I exercise.. but I do it comfortably and at a gentleman's pace 🤴
Somehow it difficult for me to say gentleman and @Gionnirocket in the same paragraph ;)...
But it does suck about Dost, and it is a warning about the over supply of companies in the ebike space.
I wonder how many car companies there once were ...
 
TMI (too much information) approaching ... back to Dost. There didn't seem to be anything wrong with their bikes, just their financing.
Just like Sonors, also recently for sale under bankruptcy. And Harley sold off Serial One to a company that buys bankrupt firms. Not my kind of bike, but some people on here really liked them.
We get enthusiastic about the technology, not the company.

What?
We were in business together. She would strip a customer's wood floor and I'd follow and apply a new finish.
 
Question... I also purchased a Dost Bike. I purchased mine from my LBS. It's nice to know you can get a replacement battery from Biktrix - So thanks for the info @RobMontanez - Now for the question - The extra battery that Dost was selling for an add-on, was a 48V 11Ah - I didn't see that specific option available on the Biktrix site? That being said, Can I use any 48V battery (piggyback) as long as I use the proper connectors? Or does it have to be the 11Ah version battery?... Also, I am not sure what connector Dost uses for the extra battery but I am sure I can find out. Thanks.

The Voltage, AH and connector are certainly important, but you also need to consider the low voltage cutoff. On most bikes, the LVC is part of the internal battery BMS. On a few others, the LVC is in the bike's controller. If you use a battery without a built in LVC in a bike without one in the controller, it is possible to over discharge and damage the battery.

This isn't a common problem and I don't know about Dost, but it is something to consider when using a battery not specifically designed for the bike.

I would never have considered that.... So thank you for the information. Just when you start to think you are getting these e-bikes figured out, something throws you a curve ball...

Makes me wish for an integrated motor/battery/controller system ...until I remember that anysuch would always be a proprietary/locked system, and how those usually work out.

Very few riders I know discharge a battery until the LVC cuts out. Most observe the 80/20 rule and don't discharge much below 20%. If you play by the rule, the LVC thing isn't that big a deal.
 
I doubt there is any Lithium Ion battery pack out there for any remotely popular e-bike without low-voltage-cut-off. the in battery cut off may be lower that what is needed to power the bike, but it would be high enough to protect the cells.

I won't argue the point. As I said, the problem is unusual, just something to be aware of.

Some overseas battery manufacturers do everything they can to keep costs down. Unfortunately, the quality of the BMS in some of these products is suspect.

Grin Technologies ran afoul of this back in 2014 with their LiGo battery line. The product was discontinued briefly due to the inferior BMS installed by their overseas supplier. The product has been redesigned and is now back on the market. Read the story here:


Two of the earlier LiGo packs I bought, died from over discharge. Grin is a reputable company and they provided a refund. I can't say enough about Grin Tech, but that's another post.

There is a reason some batteries cost $300 and others well over $1000 for the same spec. It isn't likely you will run into a LVC issue with the quality batteries provided by major manufacturers. All I'm saying is, if you buy cheap knockoffs, beware.

"if you buy cheap knockoffs, beware" seems like a good plan.
 
hmmmm.... Do you think my Raulex watch possibly dangerous?
Don't know. I haven't worn a watch since my first "smartphone " which is definitely not dangerous, in spite of all those airplane fires a while back caused by premium Samsung cells. Those were all fake news, I read..
