But don’t worry too much about missing a charge—your system will only need to be charged every couple months.

Too expensive!!!

I've used it several times

This is a Shimano OEM part and works as flawless as any other part they make. That said, there is NO reason a simple battery charger should be $130!!!! This comes off as Shimano gouging their users with a proprietary product.

Works great

This is the cable you need to connect the system to the laptop. A must have for firmware updates. Works good.
