Cross posting from the Motors sub forum as it seems more likely now this is a battery issue, so hoping someone hee can help me out.
I have a Shimano driven cargo bike with DU-EP800, SC-EM800, and battery BT-E8016. I've had it for a few years now, it's never been reliably trouble free.but I've always managed to fix any electrical gremlins.
Recently though, it's got me completely stumped. Here's the situation:
* Battery is fully charged
* Powering on from battery, computer beeps, displays boot screen for approx 7s, before going blank
* At this point both computer and battery are blank with no power delivered to pedals
* SM-PCE02 can connect, and always detects drive unit and computer. Firmware up to date,.4.1.11 and 4.3.0 respectively
* PCE02 sometimes detects an Unknown battery, reporting Firmware versions unknown, 2nd Gen Battery, SUPPORTED BY SHIMANO
* PCE02 sometimes doesn't detect even this much
* No errors reported in Drive Unit error log
* Battery error log is inaccessible
Anyone have any clue what on earth might be going on?!
