Has anyone tried charging a dual-battery R&M ebike using a Grin Satiator?

[Zaphod]

Grin now offers support for Bosch. I have asked them about dual battery charging and this was their reply: "If the batteries have single port BMS circuits, then that's fine. But for dual-port BMS circuits, we don't recommend charging two batteries via one charging port." I don't know what this means. Can anyone shed some light on this? Which does R&M use? Thanks.

If you want your Bosch warranty invalidated, that's the easy way to achieve your goal.

Sorry, no idea but i'm super curious!
Please let us know if you find out or get more details on the Grin Tech. "initial pilot/beta batch for early adapters" as i don't really know what that means either.

A dual port BMS has a separate charging port from the battery load port. A single port uses a common port for load and charging. There is a good explanation of the problem here:
