Rather than a timer, wouldn't a circuit that would disconnect the charger once the desired SOC was achieved be more useful?  I do not have the knowledge of what it is called or how it is made, but such a circuit would be of interest to me too.

Thanks for the input.  I will check out the Shinko tires.  The excel is very helpful; I was not sure how to convert metric to imperial tire sizes.

I have a 2014 S and I have recently moved from the big city (100% pavement riding) to a rural setting.  Every outing now includes time spent on gravel roads.  It's time to consider more appropriate tire options.  Most riding would still be on pavement, but I will also access fire roads and farmer's fields as well as the aforementioned gravel roads.  I know little of the topic, but am leaning towards 60/40 or 50/50 tires.  Being able to do light trails would be awesome.  What do you recommend?

Just for giggles, what would it take to have larger diameter wheels like the DS or FX on this bike?  And no, selling the S to get an FX is not really an option unless someone is willing to do a straight trade.

Thank you for all your input.  Though the functionality of the Diginow is very interesting, especially that it installs in the same place as the OEM charger, I am deterred by the cost.  I cannot afford to put that much into a charger, and at this point, I don't need to have that much charging capacity.  That's why the OEM 650w charger is interesting, because the price is right, even if the capacity is low.  If I could get it to work without much grief, it would be a viable option for me.

What I am curious about is the 'brain-box' of the charger.  If the BMS controls what the batteries receive, what does the control module of the charger do?  What search key word do I use if I want to learn more?  Charger controller?  EVCC?  I've never touched Arduino, but if detailed instructions were available, I might venture there.

There is an OEM charger for sale on this forum, but it is from 2014 FX, so only 650w.  The owner said that the connections are different, etc.  What would it take to make it work on my 2014 S?

I'm interested in the charger, is it still available?

Thank you for the great information! The Elcon TC  charger certainly looks like a great option even if it only outputs 700w from a 110v outlet.

Using the app, the cell balance fluctuates between 3 & 5 while charging; what does that mean? Is that volts or milli volts?

As far as CANbus mapping, I'm clueless. If I knew how to do it, I would certainly try.

First off, I just want to say that this is a great forum!  I’ve been lurking for a few weeks ever since I acquired a 2014 Zero S, which has been lots of fun so far. 

Unfortunately the onboard charger is dead, and has been for over a year.  The previous owner had bought the Quiq charger and had been using that without issue, which I am using now too, with the drawback that I cannot charge away from home.  I read somewhere here that using the Quiq charger without the onboard charger will not balance the battery, so that got me a little concerned as I do not want to damage or shorten the life of the battery pack.  There are only 10,500 km on the clock.  I am loathe to drop $1200 CAD on a new onboard CALEX charger that could crap out in another 10,000 km (not to mention that I am cheap ;) ).  I have read through several charger threads, but I can’t say I understand what real viable solutions are available.  I am certainly open to DIY, in fact I would prefer it, especially if I could get a faster charger going.  That being said, for the right price, 1.3kw is acceptable for the time being.

Can anyone comment on the reliability of a new OEM (Calex) onboard charger?  Have the earlier problems been sorted? I have seen that folks occasionally sell them on this forum.  Is it possible to balance the battery cells with an aftermarket onboard charger?  I’m still on a steep learning curve for all things electric. 

And if anyone reading this lives in the greater Montreal area, I’d be happy to meet up!

Cheers!
