Levo Gen 3 TCU unresponsive, battery fully charged

[daveawb]

I’ve not used my bike in 3 months, last time I used it I knew there would be a long break before I had a chance to use it or even see it.

I took it out today to clean and service. It was already quite clean as it was washed before I put it into storage. I left the battery at 40% charge and all was working fine.

Today the TCU is unresponsive. I fully charged it but nothing.

I intend to service the bike myself. Can anyone with experience of this bike (Turbo Levo Comp Alloy 23) let me know if any reasons this might be the case.

My thoughts are battery connections have corroded or come loose, possibly some water ingress that’s corroded the TCU’s connections. I read online that a faulty motor could cause this but I have no reason to believe this could be the case.

Thanks in advance for your thoughts, comments etc.

TCU has a coin CR1620 battery which is most likely depleted ... But it is not so easy to replace it:

as per posts a bove you cannot charge the TCU battery...you have to replace it. The USB port is for LBS service access..its not a charging port.

Before this post, I was blissfully and ignorantly
unaware it had its own battery, I wrongly assumed it was powered by the bikes battery. I don’t plan on trying to charge a CR1620, that would be supremely dumb.
