Hello after a fun filled 11000 miles/17700 km adventure my battery seems to have about 20% less range, i've seen what looks like a great deal at bikeable for €576,99 vat and delivery to Portugal included, however the product number differs by 2, 0275007544 (bikeable) versus 0275007546 on my original battery. I've reached out to bikeable but they are already closed for the weekend. Any knowledge here on this? TIA! Mark
