Specialized Turbo SL Charger Y Cable not working?

[Chrisgla]

Anyone who has the Y cable with Creo know if it charges the bike without the range extender battery connected?

My charger works plugged directly into bike, but not via the Y cable. I don’t have the extender battery yet- pending purchase.

The SL Y cable only works when both the bike and the range extender are connected to it.
Guaranteed info.

Thanks.. unfortunate!
I bought as a pin bent in charger and thought this was a way to minimise chance of knackering charge plug, and y has 2 to break!

Oh well, hopefully get an extender soon and have a use for it!

The interesting feature of the Y Cable is it reduces the charging current to the common denominator, which is the Range Extender. That is, charging both batteries from 5 to 100% will take 3 h 20 mins. Whenever you need to charge the internal battery faster, just use the charger plug and charge the internal battery directly.

I can't seem to get the Y cable to charge two range extenders at the same time. Is that not possible? I got two range extenders and the Y cable so that when we fly with the bikes with the main battery removed we can charge the range extenders and use them instead. Thanks all!

You cannot charge two REs with the Y-Cable. You can only charge the main battery + a single RE.

Thanks, Stefan, that is a very weird restriction! I wonder why they did this!

I was to some extent disappointed when I discovered that, too.

I would hope that the charging "intelligence" would deal with charging the main and RE and then know when a second range extender is plugged in to only charge that. Or just charge the second with the original cable.

I have found something interesting when watching the BLEvo Battery Monitor while charging both the main battery and a Range Extender with the Y-Cable:

Even if the RE is disconnected from e-bike, it is still reporting its status! (That Y-Cable must be really intelligent!)
