Back in 10 DEC 2020, I ordered two spare batteries for my employee's e-bikes through Alibaba.
48v, 10Ah, $195 each, free shipping, comes with chargers, received on 27 DEC 2020 of placing the order.
The same manufacturer have many other type of e-bike batteries available.
Pretty sure I will order again if I have need for e-bike replacement batteries.
