Error code 71

[Crazyhorse]

Has anyone had problems with error code 71 showing up??
I have had 2 spare batteries and after a short while error 71 shows and battery won't connect
Original battery is fine
Any ideas anyone please

I had also error71 on my Yamaha and original battery. I went to the service with the bike maybe 10times, I got a new battery, tried everything but error71 always come back after a while. At the end I returned the bike to the dealer, they refunded the money as they couldnt repare it. Now I have Bafang M500, not that powerful , but without any problem.

Btw. As far as I remember, service told me that there is some common/known issue with the intube battery, but they we not able to fix it.
