Evening everyone and Merry Xmas.
So I finished for my short holiday and whats the first thing you do - get the bike out!!
Unfortunately it seems that my battery is empty and now my charger will not start. I have a new EM 5.7 and It has run beautifully all summer. It has been about 4 weeks since I last used it and I may have left it on

doh!
I've checked all connections and everything is sound, but the battery is showing a low voltage 11.7V - it is a 48V machine. I have tried everything I can think of but not touching it. I've tried the 48V charger on my sons bike and all is well - starts up straight away. So it must be the battery.
Anyone got any advice as to how to move forwards. I'd appreciate it.
Thanks,
Graeme
