Hello, I'm from Herefordshire UK and I've had an electric bike for 6 years but unfortunately it needs a new battery and the Panasonic 46.8v, 8.8Ah NKY462B2 is no longer available - so I've had it re-celled BUT the company that did it didn't realise that the BCM has to be kept powered up throughout the process and the battery is now unable to power the bike for more than 100 metres. So I'm searching for advice from the community to find either someone who can repair it or find an acceptable alternative. Any suggestions welcome please! Gill
