Good morning. I have tested the battery as described above and it is coming out with a reading of -26.7 and falling and getting nothing at the throttle connector,
That's the issue there I believe. The battery voltage has dropped below the low voltage cuttoff (which is likely 30v ish)

When you plug the charger in does the light just stay green ? Presumably so in which case the voltage has dropped too far down for the BMS

Is it still under warranty ? If not there are options , it may well be possible to save/fix

For some reason I have a feeling you are local to me ? I'm in shoreham

Just if you are, and the battery is not under warranty id be happy to help you further diagnose and try to fix

I have the same kit and have taken my battery apart and performed various fixes. All under d8veh instructions but the offer is there if you want /can bring it round to me

Pm me

The BMS in your battery has shut down for whatever reason. The battery needs to be opened up to fix it. Let us know whether you want to take up Kirstin's offer, or whether you need more help.

Heard from my Dad today that the Battery had arrived from Paul at 8fun. My brother has fitted it and it's working well. I can't wait to collect it. I'll post some photo's when I get it back. In the meantime. Thanks very much to d8veh and KirstinS for your help with this :) really is much appreciated. Thanks to my Dad and brother for helping too.

KirstinS I live in Brighton so maybe we could meet up sometime? A colleague of mine who recently moved to Shoreham has just bought a Calculff (excuse spelling) electric bike.
