Shimano battery

[Gspot]

I have a shimano battery and wire harness. Could I mount it like a TEC pack and plug it into the Rosenberg port? I believe the connection to the motor is the same ? Any help is appreciated.

Anyone?

Hi Gspot,

I guess this is with relation to your Focus Bold you bought with no charger ?

You previously asked if the Specialized charger would work with it and @stiv674 came back with images of both the focus charge plug and the Spesh charge plug. There was a difference, with the focus charger having one extra terminal port in the plug.

At the time you didn't come back to say if you'd tried it and if it worked or not ?

If you have a standard external shimano battery and wiring harness/battery mount, then you should be able to install your shimano battery as an external battery and wire that to the standard motor power input port behind the top cover. I guess you're talking about connecting it to the Rosenberg port though, so I'm not sure what wiring harness you'd be using to achieve that.

I doubt it will work as I suspect that Focus have some logic built into the batteries that Shimano's batteries don't.

Several Focus agents we spoke to insisted, for example, that a TEC pack would work without the internal battery in place, but we tried and got nothing. The specialist French dealer we worked with even had the factory technician on the phone while trying and both were convinced it should work...but didn't...

My theory is that there are additional messages carried from the internal battery to the motor, which require the internal battery to be 'live' (even if charge is being provided by the TEC pack), and that the TEC pack communicates with the internal battery to allow the bike to switch on.

If you can get it to power on then I think you will have nailed it, but I'm just not sure whether a 'standard' Shimano battery will transmit the right data.
