I think the demand for your products will be principally from the corporate, people who want to run bike hires. There is no need to worry about the split between the two.
Help us build a better Ebike battery

I think you're missing my point. I know for a fact that some test houses will not certify a 48v bike or battery to EN 15194 because it says "up to 48v", so they interpret that as an absolute maximum. That means that when you take your battery there, they won't give it a certificate. So, my question is: Did you already ask your test house if they will allow a 48v battery?
for me the fact that the battery has a long life re the number of charging cycles over a slight increase in weight would be ok.
however your using 48v a lot of us run 36v ebikes so to use one of your batteries we might have to change contollers most of us would not know how to do this.
also 340w battery at 48 v range I think would be poor?
even if recharge is quick ,do I want to lug around a charger

I would like a battery that is half the current weight, can do 1500 charges before it becomes useless and most importantly is able to take me further, I can do 37 miles in a hilly area on full power, I would love to get 60 miles on full power, not really interested in faster charging.
The last thing I need is faster charging, when I go out to cycle I go out just once in the day, charging when I come back over six hours is not a problem.
An in frame battery as seen on my Oxygen bike is better.

The test houses we have spoken to in the UK deal with 48v nominal, and as long as it is under 60v during peak charging. Not sure where these other testing houses are but they are mistaken.
We can configure our system to do 36v packs, the reason why we chose 48v is it is better efficiencies all around compared with 36v. A 360w pack at 36v will perform worse than a 360w 48v pack
So this is unfortunately not for you my friend, if you are looking for a battery that is 1/2 the weight and twice the distance you are looking for a battery that is roughly 4x what is capable today, this is another decade away.
These two quotes are where it`s at in terms of what an ebike battery should be.
Forget this faster charging malarkey, most ebikers want range.
What`s the point in charging your 264Wh battery in 10 minutes when the bloomin thing will only take you 15 miles??!
Sorry, i`m out as well
No reason you can't have both. I'm currently charging a 2752kWh battery in around an hour. It could be charged even quicker, but my charger is already drawing 3000W from a single household socket, so it would require multiple phases for more power.
I have not looked into this but I assume that it's possible to submit a test bike with a battery 50% charged.
I feel almost embarrassed at the tone and nature of some of the comments on this thread.
I'm making a guess that one of the first things Inuell would have done before expending a lot of time, effort and money into this project was to make sure that what he was doing was going to gain certification. Maybe he called the 'test houses', explained the nature of his project and asked beforehand if a charging voltage of 57.6V would be acceptable for certification. Maybe he even went and had a meeting with them.
Oh guess what? He did.

Imagine if he hadn't though... I'm pretty sure if that were the case he'd have been glad for the info.
Quite so.
It's not the fact that he was asked. Its a valid question to which he gave a detailed and informative reply which at the very least showed he knew about the certification requirements and had the subject well in hand.
"We have been working with systems up to 60v for some time now, the CE and UL standard for high voltage is >60v DC so as long as you work below this during charging then you are fine. This applies the same for the EN 15194 standards as far as we have experienced."
It's the fact he was then repeatedly and aggressively pursued further on the matter in an attempt to make him look stupid and incompetent that I find embarrassing.
I get regularly aggressively questioned by some members and never worry about that.
manufacturers benefit from aggressive questioning.
