Sorry for delayed response, was a very proud boyfriend yesterday as my Girlfriend qualified as a midwife so had to dash!The reason for the thread is that the OP is disgusted at the cost of battery replacement for his E-Bike. The secondary point is the limiting effect this has on take up. You are into selling bikes, understood, how are you going to increase your sales and customer service....where does customer service come in if the customer is turned off a year or two years down the road because he's forced to pay for an overtly expensive replacement battery.
I am being deliberately argumentative because this issue affects all who buy a commercial E-Bike and I don't think, today, manufacturers really have the best interests of the customer at heart. To grow the market and your business then the cost of ownership has to be factored in and lowered accordingly....maybe it means the bike ASP needs to be higher or maybe a leased scheme for the battery is needed so replacement cost is spread out over many months...
Its the same in any vehicle industry- there is a limited warranty, but the service comes in looking after the customer post warranty. In most markets you can then get 'unbranded' components, which I sure will happen with e-bikes?
Don't worry- its good to be challenged and kept on our toes
